Checkmate patterns
Mate in 2
A forcing first move, any defence, then mate on the second.
What is the mate in 2?
In a mate-in-two you play a move so forcing that whatever the opponent tries, you mate next move. The trick is the first move — sometimes a check, sometimes a quiet move that leaves the defender in zugzwang with no good reply.
Why the mate in 2 matters
Mate-in-two is where calculation really begins, because you must account for every defence, not just the main one. That discipline — "what are all his replies?" — is exactly the habit that prevents blunders and missed wins.
How to use it to win
Find a first move that drastically cuts the king's options, then verify that every legal answer runs into mate. The hardest and best start with a quiet move; if no check works, hunt for the calm move that leaves no defence.
