Lion Defense Lions Jaw Kingside Attack in Chess

In the Lion Defense “Lions Jaw” Kingside Attack, Black uses the Lion structure to control central dark squares while preparing a kingside counterplay. The defining feature is the “jaw” setup—Black’s pieces and pawns form a flexible clamp that discourages easy central expansion and supports a later kingside thrust. In many lines, Black’s plan revolves around timely development and a pawn break that turns the kingside into the main battleground.
