Thanks for the thread. 8th grade year I played chess against Brian, he only beat me once, last day of school, I didn’t want to play, he talked me into it, he won that day, nowhere to go:
To castle in chess, you move your King two squares towards either your Rook on the kingside (kingside castling) or queenside (queenside castling). Simultaneously, the rook jumps over the king to the square immediately next to it on the opposite side.
