Learn How to Use a Discovered Check: Endgame Fork
This chess endgame shows how a forcing discovered check can completely change the evaluation. When a piece moves with tempo, it can open a line for another attacker and simultaneously create a tactical fork on the next move. In rook endgames, active king placement and passed pawns often make these ideas even stronger. Here, the key is to notice that the opponent’s king and rook coordination is vulnerable to a direct tactical shot rather than a slow positional plan.
