Grob Opening Grob Gambit Discovered Check in Chess

The grob opening grob gambit discovered check is a tactical motif where a piece that was blocking a line moves away, revealing a check on the enemy king. In the Grob Opening / Grob Gambit family, the defining feature is often an early pawn thrust and piece development that creates a line (commonly along a diagonal or file) for a discovered attacker. The “discovered check” happens immediately after the blocking piece shifts, so the opponent must respond to the revealed check rather than the original threat.
