Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Petrovs Defense and shows how a forcing tactical idea can outweigh a large material deficit. White’s attack works because the black king is slightly exposed and key black pieces are overloaded or poorly coordinated. The main lesson is that a strong tactical shot can turn a passive-looking position into a winning combination, especially when a bishop move opens lines and creates threats against both king and queen.
