Queens Indian Defense Kasparov Petrosian Variation Puzzle (Rated 1233): Win Material — Queen Sacrifice

This puzzle comes from the Queen's Indian Defense and shows how active piece placement can turn into a decisive tactical gain. White’s knight on e5 and queen pressure create a direct attack on the black king, while Black’s pieces are awkwardly coordinated. The key idea is to use king-safety pressure, pinned pieces, and forcing checks to open lines. In classical chess, these tactical moments often decide a middlegame before the position can simplify.
