Learn How to Win Material: Decisive Combination
This French Defense Rubinstein Variation puzzle shows a classic middlegame tactical pattern: a sacrifice that opens lines against the king and exposes a loose queen. White’s attack is not based on a mating net, but on forcing the king to recapture in a way that leaves the queen vulnerable. The key idea is that a discovered attack can appear when a piece moves with tempo, especially when the opponent’s king shield is already slightly weakened.
