Schiller vs Karklins in the Rossolimo: How Black can offer his e-Pawn.

If you defend the Sicilian, and are facing a Rossolimo Variation, you can select a line that is edgy and dangerous.  You must be prepared to part with a center Pawn. This game, which is a nearly flawless performance by Andrew Karklins, demonstrates Black's resources if White wishes to snatch the e-Pawn.

Schiller returned the Pawn quickly, however the center that he obtained was shaky and Black soon developed a powerful initiative.  White's pieces were disorganized and ineffective, completely unable to generate any counterplay.
