One move wins
There is exactly one move that delivers checkmate. The puzzle is complete the moment that move is played.
Look for checks first
Checkmate must put the king in check with no escape. Scan every available check and ask: can the king move, block, or capture?
Eliminate escape squares
A mating move leaves the king with zero legal moves. Make sure your piece gives check and every escape square is covered.
You play White
White always moves first. Black has no response — if your move is checkmate, you win immediately.
