Rubinstein Opening Classical Defense Puzzle (Rated 1268): Win Material — Tactical Refutation
This middlegame puzzle is built around king safety and loose pieces. White’s advanced bishop creates direct pressure near the black king, but Black can turn the tables by using the exposed bishop on g7 and the vulnerable rook on f8. The key idea is tactical refutation: when one side’s attack looks dangerous, the defender may have a forcing capture that wins material and changes the evaluation immediately. Look for checks, captures, and threats against hanging pieces before assuming the attack is sound.
