Data-mining on the game of chessI wondered what I would find if I examined a lot of chess-games. Not using conventional chess analysis but using data-mining techniques.For that I retrieved some pgn-files from the web containing 4226520 games of chess played by grandmasters and rookies. Total number of moves: 243580341 Total number of distinct moves: 7628 Average number of moves per distinct moves: 31932.399187205 Average number of moves per game: 57.63 (white+black!) 27.37% of all games end up as a draw. Most games are played on a saturday (23.00%) and are mostly won by white on that day. White wins most games on tuesday, black wins most games on saturday. White wins most games in September, black wins most games in April. The games analyzed were played between 98 and 2501. Most of them were played in 2004 (5.088%). The games were played at 44855 events at 86398 sites by approx. 346513 players. Most games (11.21%) were played in August. The most idle month (6.092%) was February. Most used openings4224001 games used a standard opening, in total 5093 distinct openings were used.Most used openings (ECO codes) with their usage percentage
Opening with which white wins and looses mostI ignored the openings that were played less then 1% of those 1 million. I'll list the 10 with the biggest number of wins for white and the 10 lowest number of wins for white. n is the number of games played to determine that percentage.+------+---------+-------+ | eco | % | n | +------+---------+-------+ | D36 | 67.5265 | 13826 | | C10 | 67.3591 | 14697 | | C41 | 62.9212 | 21363 | | B09 | 61.1395 | 15130 | | C06 | 60.5199 | 14741 | | B31 | 60.1284 | 12083 | | D35 | 59.9141 | 14020 | | E11 | 59.7699 | 12384 | | C42 | 59.5760 | 23622 | | D85 | 58.4710 | 11938 | +------+---------+-------+ +------+---------+-------+ | eco | % | n | +------+---------+-------+ | B20 | 45.2232 | 17137 | | B50 | 45.4277 | 19940 | | B25 | 45.6665 | 14064 | | A48 | 47.1792 | 19400 | | C01 | 47.4710 | 26337 | | B21 | 48.5237 | 20070 | | B02 | 48.5298 | 15478 | | A03 | 48.5911 | 14912 | | A46 | 49.0279 | 16619 | | A04 | 49.4418 | 15785 | +------+---------+-------+ Which color wins most often?White wins 1.2215 more often then black.Which moves have the most wins regardless of the piece-type
