Ponziani Opening Leonhardt Variation Puzzle (Rated 1299): Win Material — Discovered Attack

This middlegame puzzle shows how a forcing kingside strike can turn piece activity into a decisive material gain. Black’s attack works because White’s queen is active but overextended, and the king’s shelter can be opened by a tactical sacrifice. The key idea is not a random check, but a discovered attack-style sequence that drags the king into a vulnerable square and then wins the queen. In classical chess, these patterns often appear when development and king safety are out of balance.
