Alien Gambit Puzzle (Rated 1394): Win with a Pin — Middlegame Tactics

This middlegame puzzle is built around a powerful pin on the queen and king line. White’s active bishop creates immediate pressure on the black queen, and the key idea is that the queen cannot move freely without allowing a major tactical loss. When a pinned piece is forced to respond, the position often collapses into a winning material sequence. The puzzle rewards calm calculation and attention to piece alignment rather than a flashy attack.
