Four Knights Game Rubinstein Countergambit Puzzle (Rated 920): Exploit Discovered Attack — Winning Combination
This puzzle shows how a discovered attack can turn king safety into a decisive material win. Black’s pieces are lined up so that one forcing check opens the way for a direct strike on the center and the queen. White’s king looks safe at first, but the exposed coordination of the queen, bishop, and king creates a tactical target. In classical chess, these moments often arise when development is uneven and the opponent’s king is still vulnerable.
