Queens Indian Defense Kasparov Petrosian Variation Puzzle (Rated 1047): Win Material — Decisive Middlegame Tactics

This puzzle is a classic middlegame example of using active queen play to win material with tempo. White’s queen is ideally placed to attack loose pieces, and the position contains a clear pin and skewer motif around the enemy back rank and central defenders. In practical classical chess, these tactical patterns often decide games because one overloaded piece cannot defend everything at once. The key idea is to convert activity into a concrete material gain.
