Nimzo Larsen Attack Trapped Piece Beginner Puzzle (Rated 969): Win a Trapped Piece — Decisive Material Gain

This middlegame puzzle is a classic trapped-piece lesson from the Nimzo-Larsen Attack. White’s attack is built around a loose bishop and an undefended rook on the h-file, creating a tactical sequence that wins material by force. The key idea is not a flashy mate, but a clean conversion of activity into tangible gain. In positions like this, a single active bishop can overload the defense and leave a major piece with no safe squares.
