Dutch Defense Leningrad Variation Puzzle (Rated 1420): Win Material — Discovered Attack

This middlegame puzzle centers on a classic discovered attack: one piece moves with tempo, uncovering a stronger line of fire behind it. The key idea is that the opponent’s king safety is already fragile, so tactical pressure can convert into a decisive material gain. The position also features a pin and an overloaded defender, which makes the tactical sequence especially forcing. In classical chess, these patterns often decide games when active pieces coordinate against loose targets.
