Maia KDD Testing Set

These are the games used for testing models in the paper Aligning Superhuman AI with Human Behavior Chess as a Model System. The games have been converted from pgn to csv and the per move and per game information has been extracted. If you wish to see the original game files download the December 2019 standard games database release from Lichess. The game_id column matches that used by lichess. The games were selected to have both players of similar Elo Rating and for each divisions of 100 from 1000 to 25000, i.e 1000, 1100, ... 2500 there are 10,000 games. The meaning of each column should be straightforward. The per move information tends to be from the perspective of the active player, although the cp is not, instead the cp_rel columns is the relative centipawn value.
