What is a mate in 2?
A forcing first move — check, sacrifice or quiet net — followed by unavoidable mate. The defender’s best reply is already accounted for.
How to spot it
Work backwards from the mating picture: which finishing move do you want, and which first move forces the king into it against every defense?
What this set trains
The classic calculation drill — one forced reply deep, every defensive try refuted.
