Castling

Castling is a special move in chess. It allows you to move two pieces (king and rook) at the same time.

The rules are very simple.

1. Must be the first move for the king in the game
2. Must be the first move for the rook in the game
3. King can not castle when it is in check
4. Castling can not be done when pieces are between the rook and the king
