The lesson in words
Sometimes the best move is to put a stone where it will be captured. If the stones that capture it are left with just one liberty, you take them all back. That’s a snapback.
White’s group in the corner has two liberties.
Try it: Throw in a stone, let white take it, then capture the group.
Give one, take five. Next: where to play first on a 9×9 board.
