A good idea is to make a CheckPosition() function, that should be used after Make() or Unmake(). In that function you check: - that the ep square is in the limits of the board representation: a ap square with value 150 is wrong if you use a 8x8 board If you use hashtables: - that the current position's hash key is correct If you use bitboards: - that each piece in the board is included in the respective bitboards in the current position - that each piece in a bitboard is in the board in the correct position If you use piece lists: - that each piece in the piece list in the correct position in the board - that each piece in the board is in the piece list If you use incremental material evaluation: - that the material in the board is equal to the incremental variable And the same for each thing that you make in Make() or Unmake() This will do a big slowdown in you program, but you will sure that you move generation is correct.
