Caro Kann Defense Hector Gambit Puzzle (Rated 993): Win Material — Discovered Attack

This Caro-Kann middlegame puzzle shows how a single tactical shot can transform piece activity into a decisive material gain. Black’s active knight and bishop coordination create a forcing sequence that exploits a pinned piece and a vulnerable queen. The key idea is discovered attack: one piece moves with tempo, opening a line for another attacker and forcing White into a defensive reply. In positions like this, active pieces matter more than static material count.
