Isidor Gunsberg (Black) Puzzle: Win a Queen — Capture

A capture tactic is strongest when it changes more than the material count. Here, a seemingly powerful attacking setup contains an undefended major piece and a loose rook on the same wing. The defender can exploit both facts at once: the immediate capture wins the higher-value target, while opening a line creates a second attack. This is a tactical refutation of White’s material edge, transforming an active middlegame position into a favorable chess endgame for Black.
