==[[Board Representation]]==
Lc0's color agnostic board is represented by five [[Bitboards|bitboards]] (own pieces, opponent pieces, orthogonal sliding pieces, diagonal sliding pieces, and pawns including [[En passant|en passant]] target information coded as pawns on rank 1 and 8), two king squares, casting [[Castling Rights|castling rights]], and a flag whether the board is [[Color Flipping|color flipped]].
While the structure is suitable as input for the neural network, getting individual pieces bitboards requires some [[General Setwise Operations|setwise operations]] such as [[General Setwise Operations#Intersection|intersection]] and [[General Setwise Operations#RelativeComplement|set theoretic difference]] <ref>[https://github.com/LeelaChessZero/lc0/blob/master/src/chess/board.h lc0/board.h at master · LeelaChessZero/lc0 · GitHub]</ref>.
