Hikaru Nakamura (Black) Puzzle: Deflection Mate — Mate

Deflection mate is a tactical pattern in which a defending piece is lured away from a critical square, file, or rank. Once that defender is displaced, a second piece can deliver checkmate through the newly opened route. In this chess endgame, Black’s active pieces appear dangerous, but one of them is vulnerable to a forcing tactical idea. The key is to value king safety and mating geometry above material count when a defender can be redirected.
