Alien Gambit Puzzle (Rated 1224): Win the Queen — Discovered Attack

This Caro-Kann Defense puzzle shows how a single forcing idea can turn opening development into a decisive material gain. White’s bishop sacrifice creates immediate pressure on the black king and exposes the queen on d8 to a tactical hit. The key concept is a discovered attack: one piece is lured away or removed so another line opens with tempo. In practical classical chess, these patterns often decide the game before the middlegame fully begins.
