Make the opponent’s obligation to move matter.
In zugzwang, having to make a move worsens the position. It is especially useful in endgames where a king or piece must give up a critical square. Check every legal reply before claiming the opponent has no good move.
Take the diagonal opposition
The kings face each other diagonally with one empty square between. The opponent moves next; use the opposition to contest its king’s advance.
