Black's best is supposed to be 11...Rc8, although 11...Ne7 is certainly a good move. This move gives extra protection to the projected ...Bc5, so an eventual Be3 simply drops the e5 pawn.
12.Rd1 is answered by 12...Bc5! when the d3 bishop has no good discovered attack, and 12.Kh1 by 12...Bc5 13.f4 Nh6 14.Bd2 Ng4! and black is better.
Black's risky choice to grab the pawn on e5 isn't bad (factly, it may be best) provided that he will return the pawn immediately to simplify to a pawn up position: 13.Be4 Qxe5 14.f4 Nd4! 15.Qf2 Qc7 16.Rxd4 de4 17.Rxe4 Bc5 18.Be3 Bxe3 19.Rxe3 0-0.
I was looking through my database of games and stumbled upon this game that I played a few years ago. Going into this fourth round game, I was 0.5/3 in the U2200 section (I was 1808 and playing up) and was kind of depressed at how the tournament was going.
However, he played into one of my favorite openings...the Milner Barry Gambit! I've been told by multiple people that it sucks as an opening and after a6, white is lost (no Nb5 ideas). However, it appears that after a6, my opponent didn't know what to do! This is what happens when you take too many pawns without a plan in this dangerous opening!
Hope you enjoyed the game!
