Learn How to Win Material: Crushing Fork
This French Defense Rubinstein Variation puzzle shows a classic middlegame tactical refutation where king safety and piece activity outweigh raw material balance. Black’s queen invasion creates immediate pressure on the white king while also targeting loose pieces and overloaded defenders. The key idea is that a forcing check can drive the king into a worse square, after which the follow-up wins material by attacking an undefended piece. In practical terms, this is a winning combination rather than a mating attack.
