Queens Gambit Accepted Slav Gambit Puzzle (Rated 1321): Win Material — Trapped Piece Tactic

This puzzle comes from the Queen's Gambit Accepted and shows how active piece play can outweigh a temporary material deficit. White’s queen and knight coordinate aggressively against the black king and the rook on h8, creating a tactical net that turns development into concrete gain. The key idea is not a slow buildup, but a forcing sequence that exploits king safety, loose pieces, and the fact that Black’s back rank and kingside are underdeveloped. In classical chess, initiative often matters more than raw material.
