Just found this part of the forum, so I'm not sure if this one has been posted before.
If a domino piece is exactly the size of two squares of the chessboard, it would take 32 domino pieces to cover the 64 squares.
Now, if you take chessboard and cut of the a1 and h8 square, you are left with 62 squares.
Why is not possible to cover the rest of the board with 31 domino pieces?
Looking for a simple and intuitive answer.
