What is zugzwang?
Zugzwang is a situation where any move the opponent makes worsens their position. Being forced to move is the disadvantage.
Find the quiet move
The key move is not a check or a capture — it is a subtle waiting move that puts Black in zugzwang with no good reply.
Black is forced to cooperate
Whatever Black plays after your quiet move walks into a losing position. Every legal reply allows immediate checkmate.
Deliver checkmate
After Black’s forced response, you have a clean forced mate. Follow through — the puzzle is complete only once mate is delivered.
