Blunder - Counterblunder

Here's my game from tonight at chess club. My opponent was pretty strong tactically, but missed a chance to take me out after I make a very gross blunder. I missed a lot of opportunities in this game, but fortunately for me so did my opponent.

(506487) CelticDeath (1515) - My Opponent (1129) [B06]TCCC Normal, 15.03.2005
1.e4 g6 2.d4 Bg7 3.Nc3 c6 4.Bg5 I normally play the Byrne system against the Pirc. Trouble is, this isn't exactly the Pirc. I needed to pay more attention to the idiosyncracies of my opponent's unorthodox opening moves. [>=4.f4] 4...Qb6 5.Nge2 c5 [5...Qxb2 6.Rb1 Qa3 7.Rb3 Qa5 8.Bd2+/- and White's superior development compensates for the lost pawn.] 6.dxc5 Qxc5 7.Be3 Qb4 8.Bd4 Bxd4 [8...Nf6 9.Qd2 Qxb2? 10.Rb1 Qa3 11.Nb5] 9.Nxd4? [>=9.Qxd4! Qxd4 (9...Qxb2? 10.Rb1 Qxc2 11.Qxh8) 10.Nxd4+- and White's development advantage should lead to a win.] 9...Qxb2 10.Na4 Qb4+ 11.c3 Qa5 12.Rb1 a6 13.Qb3 Nc6 14.Nxc6 dxc6 15.Nb6 Be6 16.Bc4 Bxc4 17.Qxc4 [>=17.Nxc4 Qc7 18.Qxb7 Qxb7 19.Rxb7+- and again White is winning.] 17...Rd8 18.0-0 Nf6 19.Na4 0-0 [19...b5 20.Qxc6+ Kf8 21.Nc5 Kg7 (21...Qxc3?? 22.Ne6+ fxe6 23.Qxc3) ] 20.Rxb7 Rb8 21.Rfb1 Nd7 22.Qxc6? Ne5! 23.Qc7?? [Also bad is 23.Qc5 Qxa4 24.Qxe5 Rxb7 25.Rxb7 Qd1#] 23...Rxb7?? [23...Qxc7!! 24.Rxc7 Rxb1#] 24.Rxb7 Qxa4 25.h3 Qc6 26.Qxe7 Re8 27.Qb4 a5 28.Qb5 Qxb5 [28...Qxc3?? 29.Qxe8+] 29.Rxb5 Nc4 30.f3 Ra8 31.Kf2 Rd8 32.Rc5 Nb6 [>=32...Rd2+ 33.Kg3 Rxa2 34.Rxc4 Rc2 35.Ra4 Rxc3 36.Rxa5] 33.Rxa5 Ra8 [>=33...Rd3 34.Ra3 (34.Rb5 Nc4 (34...Rxc3 35.Rxb6 Rc2+ 36.Kg3 Rxa2) 35.Rb3 (35.a4 Rxc3 36.Rc5 Rc2+ 37.Kg3 Ne3 38.Rxc2 Nxc2 39.a5 Nb4 40.Kf4) ) 34...Nc4 35.Rb3] 34.Rxa8+ Nxa8 and the rest of the moves are missing with White having less than 5 minutes on the clock. White went on to win as the two pawns and White king dominated the Black knight and king. 1-0
***Update***
The above was my "quick & dirty" and flawed post-game analysis. I ran the game through Fritz afterward and found that I had missed a lot of opportunities for me to win. Fritz also disagreed with my evaluation of several of the game moves shown. I'm not sure how to get better at analyzing, but perhaps if I do enough of it I will improve.
