Preprocessed Chess Puzzle Data

[y12uc231]

Hi,

I was trying to reproduce the results for the chess puzzle dataset and it seems like the original dataset was preprocessed to convert FEN positions to a set of moves. But there can be multiple set of moves to reach a specific board position. Is it possible for you to share the preprocessing script or the preprocessed data used in the experiments.

Thanks,
Satya

Hi all,

Bumping this up in case there is anything I am missing or if there is any other info needed from my end. Appreciate helping with this.

i believe the data for the sequence of moves exists somewhere, @pavel-izmailov would know details

Hey @y12uc231, the original data from lichess is indeed in FEN notation, but also each puzzle is extracted from a real game. You can find a database of puzzles as a csv here. Each entry should contain a game id from which the position was extracted. Then, you can use the lichess api to extract the game from its id, and convert it to a move sequence notation.
