Ponziani Opening Jaenisch Counterattack Intermediate Puzzle (Rated 1385): Win Material — Tactical Refutation

This puzzle comes from the Ponziani Opening and shows a classic tactical refutation in the middlegame. White’s advanced bishop has become overextended, and Black can exploit the exposed king zone by removing the key attacker and turning the position into a winning material sequence. The idea is not a flashy mating attack, but a precise defensive move that wins time, simplifies the attack, and leaves Black with a decisive advantage.
