Old Indian Defense Fork Intermediate Puzzle (Rated 1228): Spot Mate in 2 — Queen Sacrifice
This middlegame puzzle is a classic example of king safety deciding the game. White’s queen is aggressively placed near the enemy king, and the black king’s pawn cover is weakened, especially around the h-file. The key idea is to use forcing checks that limit the king’s escape squares and overload the defenders. Even though Black has extra material, tactical threats override static evaluation when the king is exposed and pieces are poorly coordinated.
