Nimzo Indian Defense Other Variations Puzzle (Rated 960): Win with a Discovered Attack — Chess Puzzle with Theory & Hints
This middlegame puzzle shows how a direct kingside attack can force a decisive material gain when the enemy king is slightly exposed. White’s active bishop and rook coordination create a tactical refutation of Black’s queen placement and loose back-rank coordination. The key idea is that one forcing check can drag the king onto a vulnerable square, after which the queen can exploit the now-open lines and overloaded defenders. It is a classic example of activity beating material.
