Crab Opening Other Variations Puzzle (Rated 1694): Trap a Piece — Opening Tactics
This opening puzzle is about recognizing when a piece has drifted into a vulnerable square and can be trapped by a forcing pawn advance. White has more space, while Black is behind in development and has a bishop that can become awkwardly placed. The key idea is not a direct king attack, but a clean tactical refutation that wins material by limiting escape squares and forcing a capture sequence. In classical chess, these small opening tactics often decide the game early.
