Nimzo Indian Defense Puzzle (Rated 996): Deflect the Defender — Long Opening Tactic

This puzzle comes from the Nimzo-Indian Defense and shows a classic opening tactic where one defender is pulled away from an important square or piece. The position looks like a normal middlegame development battle, but the real story is material imbalance and king safety. White’s pieces are active, yet Black can use a forcing sequence to win material by exploiting a pinned piece, a loose rook, and the exposed king. The key idea is deflection: remove the defender, then invade with checks.
