After the game, he said I was winning the whole time.(well, before 33...Bxa2?). Annotated in my profile.

I'd agree with your opponent in that you were winning. I don't know if you were ahead during the whole game, but definitely after his 21.Qf4. If you had have played 21....Bxc3, you would have been at least a piece up. If he takes the bishop, you take the other knight. If he takes your queen, you take his pawn with check and then take his queen, leaving his knight pinned.

12.0-0-0 Rhe8:

<Chessmaster: After 12.0-0-0 Rhe8, blk has clear compensation in development for unit.> <Fritz: blk is winning after poor moves 12 & 13 by wht.>

13.Bf2 Qd7 <Rybka: -3.22 for 13...Qc6!>

14.Qd2 Qc6
At this point, the master played <15.b3??> to protect c4, but then retracted the move(so he violated touch-move) and said, "well, that can't be good" and played 15.g4 instead. I don't think I would've been too content to win this way, so I let it pass. As you can see, it's curtains after <15.b3?? Ba3+>.

15.g4 Bg6 <Fritz: 15...Bxg4! 16. fxg4 Qxh1 and blk has saves a tempo on game continuation, which Fritz deems more worth than bishop pair. meanwhile blk has both ...Ne4 and ...Nxg4 in his pocket.>

20.Bh4 f6 and there's no good defence for g4. if <21.Rg1>, loses c4 to CM's <21...Bd3> thou it was better than:

21.Qf4? Qxf4 Being the exchange up, I jumped at the chance to swap queens immediately, overlooking: <Rybka: -7.47 for 21...Bxc3! wins more material. -3.6 for 21...Qxc4>

22.Nxf4 Bxc3 A symplifying exchange that wrecks wht's q-side pwn structure that fritz doesn't fault, thou it does prefer <22...Bf3> a little better than <22...Bxc3>

24.Rg1 c5 Fritz doesn't condemn this move, thou it does give wht a passed d-unit. maybe better, or equally stronger was <24...Re4>.

25.d5 Fritz thinks this was a semi-blunder and prefers <25.Rg3>

26.Ne6 Rd6 fritz's second choice. first choice: <26...Rg8> I remember discarding this because I didn't want a passive rook.

27.Nxg7 Rxg4 symplifying but Rybka suggests <27...Rxc4>, fritz prefers <27...Rxc4 or ...Rb6> the queenside attack does seem more in keeping with the position.

30.Nxf6 Bxh5 I knew he wasn't going to fall for <31.Nxh5? Rh6>

31.Nxh7 Be2 <31...Rh6> was another possibility which fritz rates about as same as the game.

33...Bxa2?? I'm still kicking myself in the huevos for taking the useless a2 when the nasty <34.Nf8> threatening <35.d7> was right under my nose. Chessmaster & Rybka: <33...Be6!> paralizes passed d-unit and blk maintains big plus. Fritz: <33... Bd3> was another possibilty where blk maintains advantage.

34.Nf8 Rxd6
35.Bxd6 1/2 - 1/2
