What is a mate in 1?
One move ends the game. The challenge is pure board vision: seeing the single square where check meets no escape.
How to spot it
Scan every check systematically — queen first, then rooks, bishops, knights, pawns. One of them covers every flight square.
What this set trains
Speed and accuracy drills for beginners, warm-ups for everyone else. The foundation of all mating vision.
