Learn How to Exploit a Pin: Modern Defense Tactic
This Modern Defense middlegame puzzle is built around a tactical pin on the long diagonal and the exposed king. White’s setup looks active, but the position contains a hidden tactical refutation based on piece coordination and forcing checks. When a bishop is lined up against a king or a key defender, the pinned piece often becomes overloaded, and a seemingly safe capture can fail because of discovered pressure and tempo-gaining attacks. The lesson is to always test whether a strong-looking piece is actually hanging or tactically vulnerable.
