Nimzo Indian Defense St Petersburg Variation Puzzle (Rated 1133): Win with an Advanced Pawn — Tactical Refutation

This middlegame puzzle shows how an advanced pawn can become a tactical weapon, not just a space-gaining asset. The key idea is to use the pawn to open lines, create a discovered attack, and force the opponent’s pieces into awkward coordination. When a piece is overloaded or a defender is pinned to a key square, a simple capture can become a powerful tactical refutation that wins material and leaves the opponent’s position collapsing.
