Things like creating moves etc all need the current board and stuff like that and I didn't like the circular dependencies at all. Yeah, I could have something like this: --- Board board; Bishop piece(E4); MoveList moveList; piece.createMoves(board, moveList) --- But I didn't like that, because it simply doesn't fit my data structure(s). :) What else could a potential piece-class encapsulate? Colour and type, yes. But for these 2 things alone, I didn't think it would be worth it. (a simple struct or just a (signed) int together with abs() and sign() are enough for this) If you don't mind talking about the internals of your engine, I would like to know what functionality your piece classes provide.
