Queens Gambit Declined Albin Countergambit Discovered Attack Puzzle (Rated 1205): Spot Mate in 2 — Discovered Attack
This middlegame puzzle is a classic example of a discovered attack that turns into a forced mating net. Black’s active pieces coordinate against the white king, and the key idea is that one piece can move with tempo to open a direct line for another attacker. The position rewards tactical awareness: when the king’s shelter is loose and the opponent’s pieces are overloaded, a forcing sequence can end the game immediately. It is a strong example of a kingside attack becoming decisive.
