Learn How to Win Material: Queen Sacrifice
This puzzle comes from the Zukertort Opening, Tennison Gambit, where White uses active piece play to punish an exposed king and loose coordination. The key idea is a forcing queen sacrifice that drags the black king into the center, where tactical weaknesses become impossible to hide. Once the king is pulled away, a knight fork creates a decisive material win and leaves Black unable to keep the extra pieces safe. It is a classic example of converting development and king safety into a concrete tactical gain.
