Jerzy Ewert: … Player Profile: He has a profile in chess databases like ChessBase, which tracks his games and results. … Rating and Performance: - One result mentions a strongest win against a player rated 2200, and a loss against a player rated 1800, with his own rating mentioned as 2000 in those examples. - His game statistics show a relatively low overall winning percentage, which might suggest he was a club-level or regional player rather than a high-ranking master. The average Elo of opponents in some recorded games is around 1900. … Openings: The database tracks his performance in various openings, including the Uncommon Opening (A00), Ruy Lopez (C89, C71), Benoni Defense (A56), King's Gambit Accepted (C34), and Bird's Opening (A03). … Nationality: Polish. … Conclusion on Achievements: Based on the available snippets, there is no record of major international titles (like Grandmaster or International Master) or victories in prominent national or international tournaments. His public record seems to primarily consist of individual game statistics, which is common for players competing at a club or regional level. Note created November 2025.
