Nimzo Indian Defense Kmoch Variation Puzzle (Rated 1287): Win Material — Fork Tactics

This middlegame puzzle is about turning king safety into a decisive material gain. White’s queen and bishop coordinate against the black queen-side, where an exposed bishop and an overloaded queen create tactical targets. The key idea is to use a forcing check to drag the defender into a passive square, then exploit the loose piece on b4. In classical chess, these short combinations often work because one tactical threat creates another, leaving the opponent unable to defend everything at once.
