Polish Opening Queens Indian Variation Puzzle (Rated 1058): Win with a Fork — Decisive Material Gain
This middlegame puzzle shows a classic tactical fork where an active queen creates immediate threats against the king and a loose piece. The position is defined by piece activity, king safety, and a trapped minor piece, so the winning idea is not slow maneuvering but forcing moves that exploit overloads. In classical chess terms, Black uses a tactical refutation to convert activity into material gain while keeping White’s pieces tied down and passive.
