Queens Pawn Game Steinitz Countergambit Puzzle (Rated 1005): Fork — Decisive Material Gain
This puzzle shows a classic middlegame fork where an active knight jumps into the enemy camp and attacks multiple high-value targets at once. The key idea is not just checking the king, but using the king’s limited mobility to force a response while the fork wins material. In positions like this, piece activity matters more than static material count, especially when the opponent’s queen and rook are vulnerable to a single tactical blow.
