Why did you agree to a draw? You had a winning advantage in that position, due to white's useless bishop and your active pieces.
My draw against an IM

Sadly, that guy wasn't an IM and he did not play like one either
It was an internet simul; Like anyone else, IMs play weaker when they can't give full concentration/ are distracted.
The position is even but so unbalanced it doesn't seem drawish to me... I think the better player wins from there.
I think you played a really interesting game with that sac. You sort of sold out taking a draw there though IMO. I know it's a GREAT result for you (congrats) but you had a chance to have an exciting game that you'd learn a lot from playing. You'd probably lose because the IM's got a lot of technique to call on as the game gets end-gamy, but so what!
Here is game which I played in an ICC simul yesterday with IM John Schroer. Comments on game would be appriciated.
