English Opening Neo Catalan Declined Puzzle (Rated 1651): Win Material — Tactical Refutation
This middlegame puzzle comes from an English Opening structure where one side has a clear material edge, but the position is tactically sharp. The key idea is to notice when an attacked piece, a pinned piece, or a loose defender can be exploited for a decisive material gain. In practical classical chess, these positions often reward forcing moves that win a piece while keeping the opponent’s king safe but passive.
