Chess is a combination of the science of making accurate moves, and the art of making the opponent to make inaccurate moves.
The five most remarkable players in chess history:
1. Paul Morphy
2. Emanuel Lasker
3. Jose Raul Capablanca
4. Robert James Fischer
5. Garry Kasparov
My homepage, dedicated to analyzing the level of chess play of various chessplayers:
I'm currently doing an analysis study, where I compare roughly 2650-rated players according to chessmetrics elo rating throughout the history of chess. The aim is to find which level of play corresponds to a certain rating in different decades.
The latest version is available here:
The methods are as follows:
I analyze games between 2600-2700-rated players. Moves by both sides are subject of the analysis. Results are displayed by decades from 1860s till 2000s. Plus, I also analyze games by 2000-2700-rated players after each 100 points from 2008 for comparisons.
The games are randomly chosen from the decades.
The start point of the analysis of every game depends on a period: 1860s-70s 8-th move, 1880s-90s 9-th, 1900s-10s 10-th, 1920s-30s 11-th, 1940s-50s 12th, 1960s-70s 13th, 1980s-90s 14th and 2000s 15th move.
The minimal length of a game is 20 moves + the start point; depending on a period it may vary from 28 to 35.
The maximum length of games is unlimited. Positions with fewer than 10 pieces are not taken into account, except blunders.
Rybka 3 Default with default settings is used for the purpose of the analysis. The time per position was 5 minutes on an older computer. Now it's 65 seconds per move.
Moves outside [-2; 2] interval are discarded.
The maximum value for an error is 4.00.
A separate engine is used to calculate the complexity of positions, Stockfish 14. The complexity of a position is determined from depths 2 to 15 and by adding differences between the eval of the best and the second best moves each time Stockfish 14 finds a new move. Differences found on the depths 10-15 are multiplied by 2.
Contains new positions that have not been included in the study yet.
