English Opening Jaenisch Gambit Puzzle (Rated 1147): Win a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of using a forcing queen move to create a decisive tactical gain. White’s queen is active, the enemy rook is exposed, and the black knight is awkwardly placed near the king. The key idea is that the first check forces a response, and that response leaves another major piece vulnerable. In positions like this, a single tempo can turn pressure on the king into winning material and a clearly better end result.
