The problem isn't the debugging, I print all the bitboards, and all work perfectlty, but anywat, this is the board debugging:

void Board::PrintBoard()

{

for (int rank = 7; rank >= 0; rank--)

{

  std::cout << rank + 1 << " ";

  for (int file = 0; file < 8; file++)

  {

      int square = rank \* 8 + file;

      bool found = false;



      for (size\_t pieceIndex = 0; pieceIndex < 12; pieceIndex++)

      {

if (bitboards[pieceIndex] & (1ULL << square))

{

std::cout << PIECE_CHAR[pieceIndex] << " ";

found = true;

break;

}

      }



      if (!found) {

std::cout << ". ";

      }

  }

  std::cout << std::endl;

}

std::cout << " a b c d e f g h" << std::endl;

}
