Preprocessed Chess Puzzle Data

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

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.
