I am eager to get some feedback on this tough loss.  I thought I had an advantage after an early sacrifice, but the unbalanced position turned against me in the end.  My opponent played very well in the ending, and at the end there was nothing I could do to stop his knights.  Could I have won this by simplifying smarter?  All feedback appreciated, but please read my comments on the moves first.

I think this is definitely one of those situations where two minor pieces beat a rook. Perhaps you should have castled and not left your king so exposed

u gave up two major pieces for minor ones

11...Bxf3! brightened my day.

 

15...Qc7 ruined it =(

better was 15...Ng4   allowing for a possible Qh4 in the future. your attack should have won =)    there wasn't supposed to be an endgame!

beautiful attack. you should have won it early with 14... Ng4+. you still can get the rook and also you open up space for your queen to get into the action in the better diagonal where the Ne2 can't bother you.
