Ponziani Opening Jaenisch Counterattack Defensive Move Puzzle (Rated 1085): Win Material — Defensive Move

This middlegame puzzle comes from the Ponziani Opening, where active piece play and king safety matter more than raw material. White’s position is built around tactical pressure on the black king and loose pieces, so the key idea is to use a quiet defensive move that also improves coordination. In positions like this, the best move often looks modest but creates a direct tactical refutation of the opponent’s threats while keeping the initiative.
