Benko Gambit Accepted Dlugy Variation Puzzle (Rated 1314): Win Material — Tactical Refutation

This middlegame puzzle is about spotting a forcing tactical refutation when a loose piece and a vulnerable rook line up on the same file. White’s knight on b5 creates pressure, but Black can turn the tables by using the rook on the b-file to win material and open the a-file for a follow-up strike. The key idea is that active rooks can outweigh static weaknesses when the opponent’s pieces are overextended. In classical chess, these moments often decide the game immediately.
