Lion Defense Lions Jaw Discovered Attack in Chess

The “lion defense lions jaw discovered attack” is a tactical motif in the Lion Defense where a “jaw” move (often a pawn/line opening that clamps or threatens) sets up a discovered attack on a more valuable piece. The defining feature is that one move both releases a line (bishop/rook/queen) and simultaneously exposes an attack that was previously blocked. In practice, the Lion Defense structure lets you spring the discovered attack at the moment the “jaw” opens the right file or diagonal.
