Collinear Move Puzzle (Rated 2024): Spot Discovered Attack — Tactical Refutation
This middlegame puzzle is built around a discovered attack with a deflection idea. One piece is pinned or overloaded, so a capture on the central square opens lines for another attacker to become decisive. The key is to notice that the apparent target is not the real prize: the move sequence strips away a defender and exposes the king-side structure. In classical chess, these tactical refutations often win material by forcing the opponent’s pieces into awkward coordination.
