Mate in 3 Chess Puzzles

Mate-in-3 puzzles require finding a full three-move mating sequence: a forcing first move, the correct reply to the opponent's best defense, and a final move that delivers checkmate. These puzzles reward calculating candidate lines several moves deep rather than relying on pattern recognition alone.

Objective

This takes a full three-move plan. Start with your most forcing option and calculate the opponent's best defense before committing.
