Keep up the good work :)
I just beat a prominent rival of mine

Sure. I didn't want to shame him. I just felt very good afterwards, since I played badly in our first encounter.
It was very late and I actually played really badly, but somehow I put enough psychological pressure on him that he cracked. You'll find a less optimistic version of my analysis in this diagram, tell me what you think.
I played him in the Qa5 variation of the Sicilian Dragon. I sacced a piece and then a pawn to put pressure on him, then I guess I put so much pressure on him that he hung a rook and then a bishop. He played well but I wish he'd played better, I think my sacrifice was wholly sound :(:
