What is a checkmate?
Every puzzle in this set ends in forced mate. The lines run from single-move finishes to long king hunts, all verified from real games.
How to spot it
Mating attacks begin with counting escape squares. Remove or cover the last flight square, and every check becomes a candidate for the final blow.
What this set trains
Mate sets build finishing technique — converting winning attacks without letting the defender slip out.
