Bishop's Opening Berlin Defense Puzzle (Rated 1042): Win Material — Tactical Refutation
This middlegame puzzle shows how a single active piece can overturn a position when the enemy king is safe but the pieces around it are loose. Black’s attack works because White’s queen and bishop are tied to key squares, while the knight jump creates immediate tactical pressure with check and a fork-like idea. The position is a good example of how king safety, piece activity, and tactical refutation can outweigh a material lead.
