Canard Opening Refutation Puzzle (Rated 1182): Exploit a Pin — Crushing Middlegame Tactic
This puzzle shows a classic middlegame pin where a bishop on the long diagonal creates immediate pressure on the queen and king. The key idea is that the pinned piece cannot move without exposing a far more valuable target, so the attack becomes a forcing sequence. In positions like this, king safety matters more than material count, and a single active bishop can overload the defense and win decisive material.
