Russian Game Cozio Attack Puzzle (Rated 1429): Win Material — Discovered Attack
This Russian Game puzzle is a classic example of a discovered attack with a forcing check. Black’s active knight jump creates immediate tactical pressure on the white king and queen, while also exposing loose pieces on the kingside. The key idea is that one tactical shot can do more than one job: it checks the king, attacks valuable pieces, and opens the way for a winning follow-up. In sharp classical chess positions, activity often outweighs static material for a few moves.
