Counter Nimzo Indian Puzzle (Rated 1038): Pin — Crushing Middlegame Tactic
This puzzle shows a classic middlegame pin where a well-placed bishop creates immediate tactical pressure on the enemy queen and king. The key idea is that one piece becomes overloaded: it must defend a critical square while also staying aligned with the king. Once the pin is established, the opponent’s queen can be forced into a bad trade, leading to decisive material gain and a winning position. The position rewards accurate calculation and recognition of tactical refutation.
