Not checking produced an average score of 0.48. In the low-elo games, black checked 3.31% of the time with an average score of 0.43. In the high-elo games, black checked 2.47% of the time with an average score of 0.45. Neither AlphaZero nor Stockfish8 checked early as white in their showdown. Not checking produced an average score of 0.52. In the low-elo games, white checked 3.31% of the time with an average score of 0.47. In the high-elo games, white checked 1.63% of the time with an average score of 0.46. Is this a rookie mistake? Checking as White In my games, I put my opponents in check early. In computer chess, castling was a disadvantage. In the both high and low elo’s, castling within the first four moves was stronger than not for black and white. In total Stockfish8 castled 28 times in the first four moves, winning once, for an average score of 0.36. The average score for Stockfish8 when castling was 0.32. AlphaZero had an average score of 0.5 when castling and 0.55 without castling. Stockfish8 was black 81 times and castled 17 times in the first four moves, 20.99%. Not castling produced an average score of 0.48.ĪlphaZero was black 30 times and castled once in the first four moves, 3.33%. In the low-elo games, black castled 1.07% of the time with an average score of 0.55. Not castling produced an average score of 0.48. In the high-elo games, black castled 2.45% of the time with an average score of 0.5. ![]() 36.67% The average score for Stockfish8 when castling was 0.41. Not castling produced an average score of 0.52.ĪlphaZero was white 81 times and did not castle once in the first four moves Stockfish8 was white 30 times and castled 11 times in the first four moves. In the low-elo games, white castled 1.79% of the time with an average score of 0.57. Not castling produced an average score of 0.52. In the high-elo games, white castled 3.22% of the time with an average score of 0.58. Working with these datasets, I noticed players castled early more often than I expected. ( to get larger samples low-elo is 951- 1518 and high-elo 1842-3228, the top and bottom quintiles.) This analysis shows low-elo players can still learn from the stronger high-elo openings. First four moves: t-statistic of 7,790 and p-value 0.0.First move both sides: t-statistic of 2,899 and p-value of 0.0.First white move: t-statistic of 17,679 and p-value of 0.0.(Greater t-statistics and p-values closer to 0 indicate two distributions are different.) ![]() (Specifically, the chi2_contingency test from the scipy library.) I ran the tests for the first white move, first white and black moves, and the first four moves. To test this I ran a few chi-square tests. But my poor early performance indicates that low-elo and high-elo openings are distinct.Ĭlick here to view the interactive explorer in Google Colab. Because the start of the game is much less chaotic, I thought the opening would be when low-elo players do best. When I play chess, I feel that I fall behind early, sometimes after a few moves. ![]() Quick, stats-based ways to improve your first four moves.
