Positional Puzzle (Rated 877): Win Material — Pin Tactic
This middlegame puzzle is a classic example of a pin-based tactical refutation. One side’s active bishop and knight coordination creates immediate pressure on a queen and a loose bishop, turning a seemingly balanced position into a winning material sequence. The key idea is that a pinned piece often cannot recapture safely, so the defender’s best-looking response may fail to the simplest exchange. In positions like this, piece activity matters more than raw material count.
