Leonid Stein (Black) Puzzle: Deflect — Mate
Deflection mate is a tactical pattern in which a defending piece or king is lured away from a critical duty, allowing a mating attack to land. In this position, White faces a serious material deficit, but Black’s king is exposed and several pieces are poorly coordinated. The key idea is to use forcing checks to disrupt the defenders, remove a vital guard, and open access to the mating square.
