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.
