English Opening Pin Puzzle (Rated 1222): Win with a Pin — Decisive Material Gain
This middlegame puzzle shows how a pin can turn into a decisive material win. One piece is tied to the king, so a tactical strike on the pinned line forces a simplification that leaves the defender unable to recapture normally. The key idea is not just the pin itself, but the follow-up that exploits the overloaded king and the exposed back rank. In practical classical chess, these positions often look quiet before a forcing sequence changes everything.
