Nimzo Indian Defense Mikenas Attack Puzzle (Rated 1108): Win a Fork — Decisive Material Gain
This opening puzzle shows a classic tactical idea where active queen play exploits an exposed king and a pinned piece. White’s queen becomes the key attacker, creating a forcing line that wins material by attacking multiple targets at once. The position is especially instructive because the opponent’s bishop is overextended and the knight on c3 is tied to the king, so a single forcing move can collapse the defense and leave Black’s pieces overloaded.
