He has coached students across age groups from 6 to 65, achieving successes such as national and continental youth champions. — — His playing career includes several domestic titles and strong performances: provincial expert in 2004, champion of the Municipal Final of Experts and Masters in Revolution Square, Havana in 2006, and champion of the Provincial Final of Experts and Masters on the Isle of Youth in 2007 and 2008. He placed second in the national March 8 Cup in Matanzas in 2005, participated in the National Final in 2009, and competed in the open sections of the Capablanca Memorial in 2010-2012 with improving results (90th, 66th, and 40th places). He also took part in events like the West End tournament in Havana. — — As a coach and player shaped by the Cuban chess system (influenced by the Russian school), he emphasizes calculation, combinative vision, endgame mastery, and studying world champions' legacies. He offers personalized training, opening repertoire advice, and game analysis. — — No strong evidence indicates a primary preference for 1.b4 (the Sokolsky or Orangutan Opening) as his main weapon; his games show a range of standard openings typical for a Cuban FM of his generation. He remains active in online tournaments and continues coaching, now based in the United States. Interesting detail: beyond competitive play, he contributed to a national television chess educational program in Cuba. — — Note created July 2026. (AI)

(=1.e4 C00: French: Unusual White 2nd moves 1...e6 2.Nf3 d5 3.e5 c5 4.b4 cb4 5.d4 Bd7) — — Jaan Ehlvest was born on October 14, 1962, in Tallinn, Estonia, which was then part of the Soviet Union. — — Career and Achievements: He became a FIDE (the International Chess Federation) Grandmaster in 1987. His career is marked by several significant competitive milestones: — — He won the USSR Junior Chess Championship in 1980 and the European Junior Championship in 1983. — — He won the Estonian Championship in 1986. — — He was a member of the gold medal-winning Soviet Union team at the 28th Chess Olympiad in Thessaloniki in 1988. He later played for Estonia in the Olympiads from 1992 to 2004, and began representing the United States in 2006. — — His major tournament victories include the Reggio Emilia tournament in Italy in 1989, the New York Open in 1994, the World Open in Philadelphia (which he won or tied for first multiple times, including in 2003), and the Pan American-Continental Championship in 2008. — — At his peak, he was among the absolute elite players in the world. He reached number 5 on the FIDE world rankings in January 1991. His peak rating was 2660, achieved in January 1996. — — He was named Estonian Athlete of the Year in both 1987 and 1989. — — Opening Preferences and the 1.b4 Question: Regarding the opening move 1.b4 (known as the Sokolsky or Polish Opening, where White advances the b-pawn two squares on the first move), Jaan Ehlvest does not prefer this opening. In fact, database records show he has almost never played it in competitive tournaments—only a couple of recorded times out of thousands of games. — — Instead, his preferred opening moves as White are 1.e4 and 1.d4. He has a deep strategic understanding of positions featuring an Isolated Queen's Pawn (a single pawn on the d-file with no friendly pawns on adjacent files to protect it), which was a major theme in his 2018 book, Grandmaster Opening Preparation. When playing White, he frequently uses lines in the Sicilian Defense (such as the Rossolimo or Canal-Sokolsky Attacks, which are specific setups involving an early bishop check to avoid heavily analyzed main lines). As Black, his primary choices have historically been the Sicilian Scheveningen, the King's Indian Defense, and the Queen's Indian Defense. — — Psychology Degree: Ehlvest studied psychology at Tartu State University. He has noted that he used his psychological training during games to find positions where his opponents felt uncomfortable, allowing him to exploit their errors. — — Matches against Rybka: In March 2007, Ehlvest played an unusual handicap match against Rybka, which was one of the strongest chess engines of that era. Ehlvest played Black in all games but was given pawn odds (meaning Rybka started each game with one pawn removed to balance the difficulty). Ehlvest lost the match 2.5 to 5.5. In a rematch with different conditions (no pawn odds, but Ehlvest had White in all games, double the time, and Rybka had computational limits), he lost 1.5 to 4.5. — — Family: His younger brother, Jüri Ehlvest, was a well-known and highly regarded writer in Estonia. — — Autobiography: In 2004, he published his autobiography titled "The Story of a Chess Player". — — Federation Change: In 2006, feeling that the Estonian Chess Federation did not provide enough support, he moved to the United States and began playing under the US flag. While he is a U.S. citizen, he still spends a large portion of his time in Estonia. — — Note created July 2026. (AI)

(=1.e4 C00: French: Unusual White 2nd moves 1...c5 2.Nf3 e6 3.b4 cb4 4.d4 d5 5.e5 Ne7) — — Igor Viktorovich Kovalenko was born on 29 December 1988 in Novomoskovsk, Dnipropetrovsk Oblast, Ukrainian SSR, Soviet Union. He is a Ukrainian grandmaster who represented Latvia from 2013 to 2021 before returning to the Ukrainian federation. — — He earned the International Master title in 2008 and the Grandmaster title in 2011. His peak classical rating reached 2702 in August 2015, with a peak world ranking around 39th. He has won more than 30 classical tournaments and performed strongly in rapid and blitz formats. — — Key achievements include winning the Latvian Chess Championship in 2013 and 2014. In 2016 he finished second in the European Individual Chess Championship in Gjakova. He won the Riga Technical University Open in 2019 and has secured multiple high-level open tournament victories in a streak during 2014-2015, such as the Las Palmas Open, Bulgarian Chess Summer, Zalakaros Open, and Najdorf Memorial. He has represented Latvia in several Chess Olympiads with solid scores, including +6 =4 on second board in 2016, and later played for Ukraine, contributing to the team’s European Team Championship gold in 2025 on fourth board with an individual board win. — — Kovalenko is known for a fierce, fighting, and bold playing style that emphasizes tactical sharpness and aggression. He has defeated strong grandmasters, including players rated over 2700. Since the Russian invasion of Ukraine he has served in the Armed Forces of Ukraine for over two years while gradually returning to competitive chess. — — Regarding preferred openings, he employs a versatile and combative repertoire. With White he often favors systems that allow for dynamic play, though there is no strong evidence of heavy reliance on 1.b4 (the Sokolsky/Orangutan Opening) as a main weapon; it appears occasionally but not as a primary choice. He has been noted playing various flank and central openings suited to his aggressive approach. With Black he prepares solidly yet actively against both 1.e4 and 1.d4. He has created opening materials and coached on repertoires emphasizing practical and fighting lines. — — An interesting detail is his success in correspondence chess as one of the strongest over-the-board players in that format, using it to test and refine ideas. His career shows a pattern of strong results in open tournaments rather than relying solely on closed round-robins. — — Note created May 2026. (AI)

(=1.e4 C00: French: Unusual White 2nd moves 1...e6 2.Nf3 d5 3.e5 c5 4.b4 cb4 5.d4 Ne7) — — Andrzej Prado was born on November 14, 1953. — — He is a Polish chess player, coach, and arbiter. Over his career, he achieved a peak FIDE rating of 2115. He holds the title of FIDE Arbiter, reflecting his extensive work in officiating chess tournaments, particularly youth championships and regional leagues in Poland. — — As a coach, he has played a significant role in developing youth chess in Poland, particularly in the Lubuskie region. He has been closely associated with the chess club Stilon Gorzów, where he helped train and guide young players in their chess development. — — Regarding his opening preferences, he has indeed played the opening move 1.b4, which is commonly known as the Polish Opening, Sokolsky Opening, or Orangutan Opening. This choice is a fitting nod to his Polish nationality. In addition to 1.b4, his games show a practical approach with a variety of classical openings, and as Black, he frequently employs the French Defense. — — An interesting detail about his career is that he is widely respected in the Polish chess community as a tireless organizer. He has dedicated decades to popularizing chess among school children, organizing chess camps, and managing regional chess events. His occasional use of 1.b4 remains a signature element of his competitive games, bringing an unorthodox touch to his tournament appearances. — — Note created July 2026. (AI)

(=1.e4 C00: French: Unusual White 2nd moves 1...e6 2.Nf3 d5 3.e5 c5 4.b4 cb4 5.d4 Ne7) — — Simon Kim Williams, born on 30 November 1979 in Surrey, England, is an English chess grandmaster and author best known by his online persona and nickname "GingerGM" due to his red hair. — — He learned chess at age six and received his first FIDE rating of 2255 at age 12. He progressed through youth tournaments in the 1990s, finishing seventh in the European Under-14 Championship in 1993, tying for seventh in the European Under-20 in 1997, and taking second in the Smith and Williamson Young Masters in 1998. He earned the International Master title in 1997 or 1998. — — Williams achieved the Grandmaster title in 2008. He secured his final norm at the Hastings International Chess Congress 2005/2006 and crossed the 2500 rating threshold at Hastings 2007/2008. His peak FIDE rating reached 2550 in November 2009. As of 2026, his rating stands around 2455. — — Career highlights include finishing equal second in the British Chess Championship in 2009 (seventh in 2003), winning the British Blitz Championship in 2005, sharing first at the Southend Chess Congress all-play-all in 2009, and joint first in the London Chess Classic FIDE Rated Open in 2010 with a performance rating of 2690. He has notable wins over strong players including Magnus Carlsen and Boris Gelfand. He organized the Big Slick International tournament in Purley, London, in 2009. — — Beyond over-the-board play, Williams has built a major career as a commentator, streamer, author, and content creator. He has provided official commentary at the Gibraltar Chess Festival and for ChessBase and Chess.com events. He maintains an active YouTube channel featuring his games with commentary and analysis. In 2008, he co-founded the GingerGM publishing company with IM Simon Ansell, producing books, eBooks, and DVDs focused on aggressive play. He has created numerous Chessable courses on openings and tactics, often collaborating with IM Richard Palliser. — — His playing style is highly aggressive and uncompromising. He favors sharp, tactical battles, gambits, and attacking chess over long positional grinds. He often seeks complications and initiative early, with a reputation for bold sacrifices and creative ideas. This dynamic approach inspires his instructional materials on topics like the King's Gambit, attacking motifs, and "spicy" openings. — — Preferred openings reflect his aggressive taste. As Black, he is well-known for promoting and playing the Dutch Defense (including the Classical and Stonewall variations) and the French Defense with counterattacking ideas. As White, he has advocated systems like the English Opening (often with early d4 pushes), the London System, and various gambits or unusual lines. He enjoys and teaches tricky, non-mainstream options such as the Hillbilly Attack and other gambits for surprise value in faster time controls. While 1.b4 (the Sokolsky/Orangutan Opening) is an aggressive flank option that fits the unorthodox side of his repertoire interests, it is not documented as one of his absolute mainstays compared to his stronger associations with the Dutch or gambit-heavy lines. — — Interesting details include his entertaining personality that shines in streaming and commentary, his involvement in chess media such as the "Checkmate" show, and his early inspiration from attacking players. He has shared colorful tournament anecdotes, including one involving a naked grandmaster at an event. His content often emphasizes practical, fun chess and the "YOLO" spirit in play. — — Note created May 2026. (AI)

(=1.e4 C00: French: Unusual White 2nd moves 1...c5 2.Nf3 e6 3.b4 cb4 4.d4 d5 5.e5 Ne7) — — BIRTH DATE AND PERSONAL DETAILS: Kevin Claude Bordi, frequently registered in tournament databases as K. Bordi or Kevin Bordi, was born on March 24, 1987. — — CHESS CAREER AND ACHIEVEMENTS: Kevin Bordi is a French chess National Master (NM) who currently represents the chess federation of Monaco. He reached his peak classical FIDE rating of 2288 in February 2018. — — He is widely recognized as the most popular chess streamer and influencer in the French-speaking world. He established his Twitch channel in 2013 and his YouTube channel, Blitzstream, in 2016, building them into the largest French-language chess broadcasting platforms. He also serves as the Director of French Content for Chess.com. — — Bordi is highly accomplished in online rapid and blitz chess formats. On Chess.com, he reached a peak blitz rating of 2857 in November 2020, climbed to 2978 in April 2025, and achieved a personal milestone of 3000 Elo during a charity stream in December 2025, placing him among the top 200 blitz players globally on the platform — — In team competition, he participated in three editions of the PRO Chess League. He played for the Cannes Blockbusters team in 2017 and 2018, and took on the role of team manager for the France Roosters in 2020. — — CHESS OPENINGS AND THE 1.b4 QUESTION: The opening move 1.b4, known as the Sokolsky or Polish Opening, is not one of his preferred or standard openings. While he is known for a highly tactical style and a willingness to play unorthodox lines, his actual opening repertoire consists of other systems: White Openings: His primary and most frequent opening choice in standard classical games is the Trompowsky Attack, which begins with the moves 1.d4 Nf6 2.Bg5. He also frequently plays Queen's Pawn Games, including the Sarratt Attack and the London System, beginning with 1.d4 and 2.Bf4. In blitz chess, he is known to employ highly unusual setups, such as the Grob Opening (1.g4). He also occasionally plays the Sicilian Defense, Deferred Wing Gambit, which involves an early b4 pawn push (1.e4 c5 2.b4). Black Openings: With the black pieces, his absolute favorite and most played defense is the Scandinavian Defense (1.e4 d5), particularly the Mieses-Kotrc variation. Aside from the Scandinavian, he relies heavily on various solid lines of the Slav Defense. — — INTERESTING DETAILS: At the age of 17, Bordi traveled to Russia to participate in a chess tournament and fell in love with the country. He moved there a year later at age 18 and lived there for five years. During his five years in Russia, he made his living primarily by playing online poker, while also working at a local chess club and collaborating with the Moscow Chess Federation. He returned to France in 2015 to begin his online content creation career. — — During an online Chess.com Titled Tuesday tournament, he famously played the highly unorthodox Grob Opening (1.g4) against World Champion Magnus Carlsen and successfully managed to secure a draw in a chaotic, tactical battle. — — He is the co-author of the instructional book Chess from beginner to winner! alongside FIDE Master Samy Robin. The book is designed to make the game highly accessible by explaining complex strategic concepts using simple, everyday analogies. — — Note created July 2026. (AI)

Over his career, he achieved a peak FIDE rating of 2115. He holds the title of FIDE Arbiter, reflecting his extensive work in officiating chess tournaments, particularly youth championships and regional leagues in Poland. — — As a coach, he has played a significant role in developing youth chess in Poland, particularly in the Lubuskie region. He has been closely associated with the chess club Stilon Gorzów, where he helped train and guide young players in their chess development. — — Regarding his opening preferences, he has indeed played the opening move 1.b4, which is commonly known as the Polish Opening, Sokolsky Opening, or Orangutan Opening. This choice is a fitting nod to his Polish nationality. In addition to 1.b4, his games show a practical approach with a variety of classical openings, and as Black, he frequently employs the French Defense. — — An interesting detail about his career is that he is widely respected in the Polish chess community as a tireless organizer. He has dedicated decades to popularizing chess among school children, organizing chess camps, and managing regional chess events. His occasional use of 1.b4 remains a signature element of his competitive games, bringing an unorthodox touch to his tournament appearances. — — Note created July 2026. (AI)

Popadic,Dr (2140) - Dahlgren,James Allen (1855), Titled Tue, 2022. (=1.e4 C00: French: Unusual White 2nd moves 1...e6 2.Nf3 c5 3.b4 cb4 4.d4 d5 5.e5) — — Dr. Milorad Popadic was born on February 26, 1947, in Yugoslavia, in what is today Serbia. — — Chess Career and Achievements: Milorad Popadic achieved the title of FIDE Master during his competitive career. He competed extensively within the Yugoslav chess circuit, which was one of the strongest in the world during the latter half of the twentieth century. He represented his local clubs and participated in numerous national, regional, and open tournaments from the late 1960s through the 2000s. He maintained a consistently high playing strength, reaching a peak FIDE rating of over 2300. — — Preferred Openings: Popadic is highly regarded in chess theory for his devotion to the Sokolsky Opening, which begins with the move 1.b4. This opening is also widely known as the Polish Opening or the Orangutan. While most master-level players employ 1.b4 only as an occasional surprise weapon, Popadic adopted it as his absolute primary weapon with the white pieces. He analyzed its complex structures deeply and proved its viability against top-tier opposition. His games and novel concepts contributed significantly to the theoretical development of the opening, and his name is frequently cited in specialized opening literature as a leading authority on 1.b4 lines. — — Interesting Details: Outside of the chess world, he was a medical doctor by profession. Balancing the intense academic and practical demands of a medical career with competitive master-level chess is a rare accomplishment. His preference for 1.b4 reflected an independent and creative philosophy of the game. By choosing a flank opening that was rarely played at the top level, he successfully bypassed heavily memorized, computer-generated mainlines, forcing his opponents into territory where understanding of unique positional plans was more important than home preparation. — — Note created July 2026.

He first encountered chess at home at the age of 5 and played in his first tournament a year later. Since 2012 he has regularly competed in national and international events. He was initially a member of SK Komenda and later joined ZSK Maribor. — — He holds the title of FIDE Master. His peak standard rating has reached around 2400, with recent ratings in the 2380s (standard), lower 2300s (rapid), and around 2330 (blitz). He has shown consistent strength as a young talent, including multiple runner-up finishes in Slovenian youth championships across various age groups and time controls in the mid-2010s. — — Notable early achievements include second places in the National Championship Rapid U10 (2014), Schools U12 (2015 and 2016), Classic U14 (2017), Schools U15 (2018), and third in Rapid U14 (2017). He also placed 7th in the European Youth Chess Championship Rapid U14 in 2017. In later years he has competed in open tournaments and achieved wins against strong opponents, such as a victory over grandmaster Sanan Sjugirov (rated over 2690 at the time). — — Regarding openings, available data from game databases indicate he employs a range of systems. As White, common choices include variations of the English Opening and Queen's Pawn games. There is no prominent evidence that 1.b4 (the Polish/Orangutan Opening) is a primary or preferred choice in his repertoire; it appears he favors more mainstream or flexible setups. As Black, he has faced and used responses typical in 1.e4 and 1.d4 lines. — — Marn continues to participate actively in tournaments as of 2026, maintaining a solid level for a player in his early twenties and contributing to Slovenian chess as a promising talent from a young age. — — Note created July 2026.

(=1.e4 B28: Sicilian: 2 Nf3 a6 (O'Kelly Variation) 1...c5 2.Nf3 a6 3.b4 cb4) — — Aryan Tari was born on June 4, 1999, in Stavanger, Norway. — — Chess Career and Achievements: Tari began playing chess at the age of five. He advanced rapidly through the ranks, winning the junior section of the Norwegian Chess Championship in 2012, which qualified him for the elite national championship section the following year. In 2013, he achieved both his FIDE Master and International Master titles. — — He won his first senior Norwegian Chess Championship in 2015 at the age of 16. This made him the third-youngest player in history to win the national title, following only Simen Agdestein and Magnus Carlsen. He secured his Grandmaster title shortly after, which was officially awarded by FIDE in March 2016. — — His most significant international victory occurred in 2017 when he won the World Junior Chess Championship in Tarvisio, Italy, scoring 8.5 out of 11 points and securing the title on tiebreaks. He won the Norwegian Chess Championship for a second time in 2019. He reached his peak classical FIDE rating of 2672 in July 2022, which placed him 70th in the world at that time. He has consistently been ranked as either the second or third highest-rated player in Norway. — — Preferred Openings: Regarding 1.b4 (known as the Sokolsky or Orangutan Opening), this is not one of Tari's preferred openings. He relies on standard, deeply analyzed mainstream lines rather than unorthodox flanking openings in classical games. — — With the white pieces, he primarily prefers 1.e4. His most frequently played setups include the Closed Sicilian (particularly the Grand Prix Attack), the Sicilian Canal Attack, the French Defense, and the Ruy Lopez. He also occasionally opens with the English Opening (1.c4). — — With the black pieces, his primary choices against 1.e4 are the Caro-Kann Defense and the Sicilian Defense. Against 1.d4, he regularly plays the Grünfeld Defense or the Queen's Gambit Declined. — — Interesting Details: His parents immigrated to Norway from Iran before he was born, and he grew up in Lierskogen, outside of Drammen. — — At the 2022 Norway Chess tournament, Tari achieved a major personal milestone by defeating Magnus Carlsen for the first time in a professional tournament setting, winning their Armageddon tiebreak match. — — Beyond playing, he has worked behind the scenes at the highest levels of chess, serving as an opening second and coach for world number two Fabiano Caruana during the 2025 Norway Chess tournament. — — He has balanced his professional chess career with academic pursuits, moving to the United States to study business at the University of Missouri, where he also competes for the university's chess team. — — Note created July 2026.

He holds the International Master title, awarded in 2025. — — He began playing chess at the age of six. One of his early notable results was winning the Maharashtra State Senior Championship at age 13 in an open event without age restrictions. He has also won the Asian Championship in Sri Lanka. — — In academics, he scored 98 percent in his 10th CBSE board exams while actively managing chess commitments, demonstrating strong discipline in balancing both. He has credited chess training with helping build focus, concentration, and memory skills that aided his studies. — — Key career milestones and achievements include earning his first IM norm at the Budapest Spring Festival 2024 with 5.5/9 and crossing 2400 live rating. His second IM norm came at the 26th Tamil Nadu IM Round Robin in Coimbatore with 7/9. He completed the IM title and scored his maiden GM norm at the SixDays Budapest March GM-A Round Robin with 7/9. — — In November 2025, at the Commonwealth Chess Championship in Kuala Lumpur, he won gold in the Under-16 Classical section with an unbeaten 8/9 and bronze in the Under-18 Blitz with another 8/9.

(=1.e4 B30: Sicilian: 2...Nc6 3 Bb5, lines without ...g6 1...c5 2.Nf3 Nc6 3.b4 cb4 4.d4 e6) — — Ivan Yeletsky is a Russian chess player born on August 4, 1999. He holds the title of FIDE Master, which he received in 2014. He has represented Russia in various junior and open competitions. His peak classical Elo rating reached 2504, with a more recent standard rating around 2421, rapid 2387, and blitz 2480. — — Yeletsky began playing chess at the age of seven. He participated in Russian junior championships, achieving a Russian U19 champion title in the team event and individual successes in youth categories. He has competed in events such as the Russian Higher League and Moscow Open. In online play he maintains active profiles and has recorded wins against strong opponents, including a notable game against Fabiano Caruana in a rapid or blitz format. He has also served as a chess coach. — — His opening repertoire as White includes the English Opening in several variations, the Zukertort Opening, and occasional use of 1.b4 (the Sokolsky or Orangutan Opening), as seen in games from tournaments like the Chigorin Memorial. As Black he has frequently employed the Sicilian Defense (including Najdorf lines), Caro-Kann Defense, Alekhine's Defense, and Grunfeld Defense. His games show a mix of main-line and less common systems. — — Yeletsky's playing style features solid preparation and tactical alertness, reflected in an overall win rate exceeding 56 percent across analyzed games, with strong performance when playing White. He demonstrates competence in both classical and faster time controls, with blitz ratings often higher than classical. — — His legacy rests on consistent participation in Russian chess structures from junior levels into open events, contributions as a coach, and an ability to compete against higher-rated players on occasion.

(=1.e4 B30: Sicilian: 2...Nc6 3 Bb5, lines without ...g6 1...c5 2.Nf3 Nc6 3.b4 cb4 4.d4 e6) — — Oskar Wieczorek was born on June 13, 1994, in Wroclaw, Poland. — — His chess career is highlighted by his progression through the international ranks, culminating in earning the Grandmaster title in 2019. Prior to that, he achieved the International Master title in 2013. He has actively competed in various team and individual events across Poland and Europe, including representing his club in the Polish Team Chess Championship, known as the Sygnity Ekstraliga, where he fulfilled requirements for his Grandmaster norms. His peak international Elo rating reached 2512 in May 2023. — — Regarding his opening repertoire, he relies primarily on mainstream, conceptually classical structures rather than eccentric flank openings such as Sokolsky's Opening, which begins with 1.b4. When executing his strategies, his most frequent selections include the Caro-Kann Defense, particularly the Modern Variation, as well as the Sicilian Defense, with a specific focus on the Najdorf and Taimanov variations. In open games, he regularly employs the Four Knights Game. Additionally, his games demonstrate familiarity with systems like Alekhine's Defense and the French Defense, keeping his approach grounded in main-line chess principles. — — An interesting detail concerning his title progression is that his path to the Grandmaster title was officially secured through strong performances in the Polish Team Chess Championship. The Polish Ekstraliga is widely regarded as an intensely competitive environment, frequently featuring elite international players, which meant he earned his ultimate chess title by battling in a demanding and high-stakes team format rather than relying solely on traditional individual open tournaments. — — Note created May 2026.

(=1.e4 B40: Sicilian: 2...e6, Unusual lines 1...c5 2.Nf3 e6 3.b4 cb4 4.d4 d6) — — Anatoly Moskvin was born on September 8, 2002. — — In his chess career, he achieved the title of Candidate Master, which is abbreviated as CM. His official FIDE identification number is 24199990. In over-the-board classical chess, his peak rating reached 2201, a milestone he achieved in September 2021. — — Regarding his preferred openings and the move 1.b4, he does not typically play 1.b4 as his very first move. Instead, he frequently utilizes an early b4 expansion as the Wing Gambit against the Sicilian Defense. This setup follows the introductory moves 1.e4 c5 2.Nf3, at which point he offers the b4 pawn to disrupt Black's pawn structure and gain rapid piece activity. Aside from this specific gambit, his most frequently played opening systems include standard variations of the Sicilian Defense, the French Defense, and the Caro-Kann Defense. — — As an interesting detail, he maintains a highly active presence in online chess circles under the username Tolyanius. His online blitz and bullet ratings on digital platforms are significantly higher than his classical over-the-board rating, regularly climbing above the 2700 and 2800 mark. This high rating allows him to regularly compete against elite international grandmasters in online events such as Titled Tuesday. — — Note created July 2026. (AI)

Guzman Lozano,C (1870) - Liu,Zachary Hankun (1945), Titled Tue (5), 2024. (=1.e4 B40: Sicilian: 2...e6, Unusual lines 1...c5 2.b4 cb4 3.d4 e6 4.Nf3 Nf6) — — Campo Elias Guzman Lozano, where the C denotes his first name Campo, was born in 1953. — — Chess Career and Achievements: He represents the Colombian chess federation and holds the official FIDE title of Candidate Master (CM). His FIDE identification number is 4403746. Over his competitive career, he achieved his peak FIDE classical rating of 2060 in September 2013. He has remained an active tournament competitor over several decades, participating in various national and regional chess tournaments within Colombia, including events in cities like Medellin, Bogota, and Pereira, continuing to play well into his seventies. — — Preferred Openings: When playing with the white pieces, his most frequent choices revolve around Queens Pawn systems. He heavily favors the Trompowsky Attack, often utilizing the Raptor Variation, as well as the Levitsky Attack. He also regularly opens with flank setups such as the Nimzowitsch-Larsen Attack or the Reti Opening. — — Regarding your specific question about 1.b4 (the Polish or Sokolsky Opening), it is not a preferred or characteristic opening for him as White. Instead of opening with the b-pawn to the fourth rank, his primary flank preference is the closely related Nimzowitsch-Larsen system starting with 1.b3 or Reti lines. He has, however, encountered 1.b4 from the black side in competitive matches. — — When commanding the black pieces, he frequently relies on the Sicilian Defense to counter 1.e4, with a particular affinity for lines such as the Lowenthal Variation. He also uses Benoni setups and defenses against Queens Pawn openings. — — Interesting Details: His chess career is characterized by remarkable competitive longevity. He achieved his peak international rating of 2060 in 2013 around the age of sixty, a period when many players see a decline in their ratings. He remains a highly active figure in the Colombian chess scene, playing over a thousand tracked games in competitive databases spanning across classical, rapid, and blitz formats up to the current year of 2026. — — Note created July 2026.

(=1.e4 B40: Sicilian: 2...e6, Unusual lines 1...c5 2.Nf3 e6 3.b4 cb4 4.d4 Nf6 5.Bd3 Be7) — — Shukhrat Makhmudov was born in the year 1964. — — He is officially registered as a chess player under the chess federation of Uzbekistan. In over-the-board classical play, his official FIDE rating historically hovers between 1580 and 1636. His over-the-board tournament history includes competing in regional events within Uzbekistan, such as the Karshi Open, where he has participated in the Senior 60+ division. — — His competitive presence is notably active in digital formats. On the chess.com platform, he holds a Candidate Master title and maintains an online blitz rating that stands above 2100. His primary chess career footprint involves regular participation in weekly elite online blitz events, specifically the Titled Tuesday tournaments, where he regularly plays against international masters and grandmasters. — — Regarding your question about 1.b4, there is no evidence in competitive databases indicating that 1.b4, also known as the Sokolsky or Polish Opening, is his preferred opening choice. When playing white, his tracked games show a preference for traditional opening structures, frequently initiating games with 1.e4 or playing setups related to the English Opening and the King's Indian Defense. — — An interesting detail regarding his career is the significant gap between his official over-the-board classical rating and his online blitz proficiency. He acts as a highly competitive blitz specialist in fast-paced time controls. This proficiency has allowed him to secure major upsets against much higher-rated titled opponents, including a clean twenty-six move victory against an opponent rated over 2200 during an online tournament in 2023. — — Note created July 2026.

(=1.e4 B40: Sicilian: 2...e6, Unusual lines 1...c5 2.Nf3 e6 3.b4 cb4 4.d4 Nf6 5.Bd3 Be7) — — Donat Daroczi (also spelled Donát Daróczi) is a Hungarian chess player born in 2005. He holds the FIDE Master title and has competed actively in both over-the-board and online events, with a peak standard rating around 2256 and a recent standard rating near 2157. — — As a young talent from Hungary, he has participated in numerous youth championships and open tournaments in his country and abroad, including events like the Hungarian Youth Championships, Zalakaros Open, and various Budapest internationals and IM norm tournaments. He has scored notable wins against stronger or titled players, such as defeating a 2500+ rated opponent in one recorded game, and has performed well in rapid and blitz formats, with ratings in those reaching the low 2200s at times. He remains an active competitor in online titled events and weekend opens. — — Regarding openings, Daroczi shows flexibility but has employed uncommon first moves as White. He has used systems such as the Nimzowitsch-Larsen Attack (1.b3 or related) and the Zukertort Opening (1.Nf3), alongside more standard choices like 1.e4 and 1.d4 lines. As Black, he has faced or played into various defenses including Sicilian, French, and Catalan structures. While 1.b4 (Sokolsky/Polish/Orangutan Opening) appears in some databases connected to games involving him or similar lines, it is not documented as his primary or most frequent choice; he leans more toward flank and hypermodern setups that allow for creative, unbalanced play. — — An interesting aspect of his profile is his involvement in prize-money online tournaments and consistent activity across platforms like Chess.com, where he has faced grandmasters in rapid events. Like many players of his generation, he combines solid classical foundations with practical, aggressive play in faster time controls. — — Note created May 2026. (AI)

(=1.e4 B40: Sicilian: 2...e6, Unusual lines 1...c5 2.Nf3 e6 3.b4 cb4 4.d4 Nf6) — — Ignacio Cavadini is a chess player from Argentina born in 1986. He resides in Buenos Aires and joined Chess.com in 2013. He holds the title of National Master and maintains an online profile there as a titled player. His FIDE identification number is 117480. His highest recorded standard rating reached 2111 according to ChessBase data with a latest listed standard rating of 1992. Rapid rating peaked at 1987 and blitz at 1878 with some ratings listed as inactive in official records. He has competed in both over-the-board events in Argentina and numerous online formats. — — His chess career spans classical tournaments and fast time controls. He participated in events such as the Liga Nacional Superior, IRT Jose Rubinstein, Villa Martelli open, Abierto Internacional Pro-Am, and team competitions. In online play he engages regularly in bullet, blitz, and rapid arenas on platforms including Lichess and Chess.com as well as Titled Tuesday events. Game records show activity from the mid-2000s through 2025 with participation against a range of opponents including titled players and grandmasters. He achieved a draw against GM Rafael A Vaganian in a 2025 Titled Tuesday encounter. Total recorded games on Chess.com number around 70 with a win percentage near 30 percent in the available sample. — — Cavadini frequently employs 1.b4 as White known as the Polish Opening or Sokolsky Opening or Orangutan. He features this move in many documented games often followed by Bb2 development and lines such as 1.b4 e5 2.Bb2 or 1.b4 d5 2.Bb2. He also incorporates related irregular setups including 1.e4 c5 2.b4 in Sicilian structures or transpositions into A00-A06 ECO codes. As Black he responds variably depending on the opponent. His approach in fast formats emphasizes quick piece development central control and tactical opportunities. — — His style leans toward aggressive play particularly in bullet and blitz where he seeks early initiative material gains or direct attacks. Annotated games display tactical motifs including pins deflections discovered attacks and king hunts leading to checkmates in several wins. In slower formats he shows positional elements such as pawn advances and structure exploitation though he remains comfortable in unbalanced irregular positions. — — No public testimonials or extensive legacy statements appear in available sources. He received feature placement on Marek's 1.b4 world site in November 2025 highlighting his consistent use of the Polish Opening among enthusiasts of that system.

Guzman Lozano,C (1900) - Arias Igual,A (2305), Titled Tue (7), 2024. (=1.e4 c5 2.b4 cb4 3.d4 Nf6) — — Campo Elias Guzman Lozano, where the C denotes his first name Campo, was born in 1953. — — Chess Career and Achievements: He represents the Colombian chess federation and holds the official FIDE title of Candidate Master (CM). His FIDE identification number is 4403746. Over his competitive career, he achieved his peak FIDE classical rating of 2060 in September 2013. He has remained an active tournament competitor over several decades, participating in various national and regional chess tournaments within Colombia, including events in cities like Medellin, Bogota, and Pereira, continuing to play well into his seventies. — — Preferred Openings: When playing with the white pieces, his most frequent choices revolve around Queens Pawn systems. He heavily favors the Trompowsky Attack, often utilizing the Raptor Variation, as well as the Levitsky Attack. He also regularly opens with flank setups such as the Nimzowitsch-Larsen Attack or the Reti Opening. — — Regarding your specific question about 1.b4 (the Polish or Sokolsky Opening), it is not a preferred or characteristic opening for him as White. Instead of opening with the b-pawn to the fourth rank, his primary flank preference is the closely related Nimzowitsch-Larsen system starting with 1.b3 or Reti lines. He has, however, encountered 1.b4 from the black side in competitive matches. — — When commanding the black pieces, he frequently relies on the Sicilian Defense to counter 1.e4, with a particular affinity for lines such as the Lowenthal Variation. He also uses Benoni setups and defenses against Queens Pawn openings. — — Interesting Details: His chess career is characterized by remarkable competitive longevity. He achieved his peak international rating of 2060 in 2013 around the age of sixty, a period when many players see a decline in their ratings. He remains a highly active figure in the Colombian chess scene, playing over a thousand tracked games in competitive databases spanning across classical, rapid, and blitz formats up to the current year of 2026. — — Note created July 2026.

Guzman Lozano,C (1900) - Bambino Filho,A (2165), Titled Tue (2), 2024. (=1.e4 c5 2.b4 cb4 3.d4 g6) — — Campo Elias Guzman Lozano, where the C denotes his first name Campo, was born in 1953. — — Chess Career and Achievements: He represents the Colombian chess federation and holds the official FIDE title of Candidate Master (CM). His FIDE identification number is 4403746. Over his competitive career, he achieved his peak FIDE classical rating of 2060 in September 2013. He has remained an active tournament competitor over several decades, participating in various national and regional chess tournaments within Colombia, including events in cities like Medellin, Bogota, and Pereira, continuing to play well into his seventies. — — Preferred Openings: When playing with the white pieces, his most frequent choices revolve around Queens Pawn systems. He heavily favors the Trompowsky Attack, often utilizing the Raptor Variation, as well as the Levitsky Attack. He also regularly opens with flank setups such as the Nimzowitsch-Larsen Attack or the Reti Opening. — — Regarding your specific question about 1.b4 (the Polish or Sokolsky Opening), it is not a preferred or characteristic opening for him as White. Instead of opening with the b-pawn to the fourth rank, his primary flank preference is the closely related Nimzowitsch-Larsen system starting with 1.b3 or Reti lines. He has, however, encountered 1.b4 from the black side in competitive matches. — — When commanding the black pieces, he frequently relies on the Sicilian Defense to counter 1.e4, with a particular affinity for lines such as the Lowenthal Variation. He also uses Benoni setups and defenses against Queens Pawn openings. — — Interesting Details: His chess career is characterized by remarkable competitive longevity. He achieved his peak international rating of 2060 in 2013 around the age of sixty, a period when many players see a decline in their ratings. He remains a highly active figure in the Colombian chess scene, playing over a thousand tracked games in competitive databases spanning across classical, rapid, and blitz formats up to the current year of 2026. — — Note created July 2026.

Guzman Lozano,C (1835) - Mrudul,Dehankar (1965), Titled Tue (4), 2024. (=1.e4 c5 2.b4?? cb4-/+ 3.d4 g6) — — Campo Elias Guzman Lozano, where the C denotes his first name Campo, was born in 1953. — — Chess Career and Achievements: He represents the Colombian chess federation and holds the official FIDE title of Candidate Master (CM). His FIDE identification number is 4403746. Over his competitive career, he achieved his peak FIDE classical rating of 2060 in September 2013. He has remained an active tournament competitor over several decades, participating in various national and regional chess tournaments within Colombia, including events in cities like Medellin, Bogota, and Pereira, continuing to play well into his seventies. — — Preferred Openings: When playing with the white pieces, his most frequent choices revolve around Queens Pawn systems. He heavily favors the Trompowsky Attack, often utilizing the Raptor Variation, as well as the Levitsky Attack. He also regularly opens with flank setups such as the Nimzowitsch-Larsen Attack or the Reti Opening. — — Regarding your specific question about 1.b4 (the Polish or Sokolsky Opening), it is not a preferred or characteristic opening for him as White. Instead of opening with the b-pawn to the fourth rank, his primary flank preference is the closely related Nimzowitsch-Larsen system starting with 1.b3 or Reti lines. He has, however, encountered 1.b4 from the black side in competitive matches. — — When commanding the black pieces, he frequently relies on the Sicilian Defense to counter 1.e4, with a particular affinity for lines such as the Lowenthal Variation. He also uses Benoni setups and defenses against Queens Pawn openings. — — Interesting Details: His chess career is characterized by remarkable competitive longevity. He achieved his peak international rating of 2060 in 2013 around the age of sixty, a period when many players see a decline in their ratings.
