Wesley So crashed through Magnus Carlsen's defenses with a devastating attack after Carlsen played f6 in their Norway Chess 2026 encounter. The move weakened Carlsen's kingside irreparably, allowing Wesley to launch a mating attack that forced resignation. Carlsen's uncharacteristic mistake underscores a fundamental principle: pawn moves in front of your king demand respect. Wesley's execution was clinical. One tactical blow landed after another until the position became hopeless.
