Learn How to Spot Interference: Mate in 2
This classical chess puzzle is a clean example of interference: a piece is placed so it blocks a key defensive line and leaves the king exposed. The position also features a skewer motif, where a valuable piece is lined up behind another target. In practical terms, the winning idea is to force the king into a narrow response and then use the overloaded geometry around the c5 square to deliver mate. It is a strong middlegame tactic, not a slow endgame grind.
