Alexander Beliavsky (Black) Puzzle: Trade — Rook Tactics

A well-timed trade can overturn impressive-looking piece activity. Here, one side’s active rook and bishop create pressure along the open file and seventh rank, but their coordination also leaves a tactical target. By exchanging at the right moment, Black removes a key attacker and emerges with a decisive material edge. This is a useful middlegame lesson: active pieces are valuable, yet activity must be backed by tactical safety and sufficient defenders.
