Two Knights with 8.Qf3Edit

8. Qf3Edit

Develops the queen and pins the c6 pawn, as cxb5 gives Qxa8.

This variation has become popular in light of the game Nigel Short vs Mark Hebden in which Short won convincingly. Apparently, computer analysis has suggested that Black hasn't enough compensation for the pawn. Black now faces the prospect of giving up a second pawn or the a8 Rook in order to maintain a development advantage.
