Learn How to Win Material: Discovered Attack
This Slav Defense puzzle shows a classic tactical refutation where activity outweighs raw material. White’s queen and rook coordination looks dangerous, but Black can exploit the alignment of pieces on the c-file and the exposed queen. The key idea is a discovered attack: one piece moves with tempo, opening a line for another attacker and forcing a sequence that wins material. In sharp middlegame positions, a single forcing move can turn a passive defense into a decisive counterblow.
