1. It can only occur if there are no pieces standing between the king and the rook.
2. Neither king nor the rook to be castled with may have moved from its original position. (The other rook may have already moved.
3. There can be no opposing piece that could possibly capture the king in his original square, the square he moves through or the square that he ends the turn.
The king moves two squares toward the rook he intends to castle with (this may be either rook). The rook then moves to the square through which the king passed.
