Preventing 3 Qc3 and creating the threat of 3...c4, which White parries with his next move.

Heading for h6,

Preparing Be4 and Bxg6, a plan impossible to stop.

Sacrificing a pawn in order to enter with the bishop on a4 and c2.

The only way to parry the threat of 6...h4.

Black soon won.

To clear the long diagonal for the bishop.

Preferable was 2.Bc5! dxe4 3.Qe2 with unclear play.

With ideas like ...Ne5-d3 and ...N7b6-a4, Black enjoys excellent attacking prospects.
