Get captured pieces #231

Closed PedanticHacker closed 6 years ago

PedanticHacker commented 6 years ago

Is there a (simple) way in python-chess to get captured pieces? I want to display an SVG image for each captured piece.

For every piece type(pawn,knight...queen) just popcount the bitboard(in BaseBoard) and subtract from the maximum number of that piece type.

For variants that modify the number of pieces you'll just have to count how many of each piece.

Thanks. 😉
