What is a mate in 3?
Three-move mating combinations with branching defenses: sacrifices to strip the king, quiet second moves that close the net, and precise final blows.
How to spot it
Anchor on the defender’s king shelter. Each of your three moves should remove a defender, a flight square or a blocker — nothing else.
What this set trains
Real calculation training — holding a small tree of variations in your head to a forced finish.
