Dataset Card for Chess Puzzles Images (large)
This dataset contains 1,249,999 chess board positions in JPG format, derived from Lichess puzzles. Each image is accompanied by a shortened FEN string, indication for the color to play as, castling and en passant availability, and best moves in standard algebraic notation. The fields are as follows:
image:image, A visual representation of the chess board showing the current piece arrangement.board_state:string, A shortened FEN (Forsyth–Edwards Notation) string representing the piece placement on the board after the opponent's move. This state indicates the position from which the player must find the correct continuation.active_color:string, Indicates which player's turn it is to move. "w" for White to move and "b" for Black to move.castling_rights:string, Indicates the remaining castling options for both players. If neither side has the ability to castle, this field uses the character "-". Otherwise, this field contains one or more letters: "K" if White can castle kingside, "Q" if White can castle queenside, "k" if Black can castle kingside, and "q" if Black can castle queenside.en_passant_target_square:string, Specifies the square in algebraic notation where an en passant capture is possible. If no en passant capture is available, this field contains "-".best_continuation:string, The solution to the puzzle, consisting of "only moves" - moves that are significantly better than any alternatives. For mate-in-one puzzles, multiple solutions may exist if they all result in checkmate.
