1. d4 d5 2. c4 {Finally someone lets me play an opening I'm familiar with...}
2... c5 {But I'm not familiar with that response!} 3. e3 Nc6 4. Nf3 f6 5. Nc3
{I took a long time on this move since I thought he was preparing for e5.}
5... e6 6. b3 Bd6 7. cxd5 {I made this capture with the intention of
developing my bishop to b5 for the pin.} 7... exd5 8. Bb5 {maybe I should have played Nxd5 to grab that pawn} 8... a6 9. Ba4? {I made
this move quickly because in other games I've maintained a pin that way, but
too late noticed that the bishop had no escape squares. I was certain b5 was
next.} 9... Rb8 {I didn't understand this move, but I was relieved.} 10.
Bxc6+ {I wasn't going to wait for b5 any longer.} 10... bxc6 {I was happy to
double his pawns but not to let the rook have the mostly-clear file. Perhaps
that was the intent of 9...Rb8?} 11. O-O c4 12. bxc4 dxc4 {Now I noticed he
had two unprotected pawns.} 13. Qa4 {Attacks both of them!} 13... Ne7
{Probably his best reply. } 14. Qxc4 Rb4 15. Qd3 {Here I had 57 minutes
left.} 15... O-O {My opponent had 62 minutes left. At this point I'm wondering
if the pawn grab was too aggressive and my queen would be continually
attacked.} 16. Bd2 c5 17. Ne4 c4 18. Qc2 Rb5 19. Nxd6 Qxd6 20. Qxc4+ Be6 21.
Qc3 {36 minutes left.} 21... Rc8 22. Qd3 Bf5 23. e4 {32 minutes left. I wasn't
happy with this move but I wanted to give my queen more retreat options.}
23... Bg6 24. Rfc1 {25 minutes left. I'm wanting to exchange pieces and
simplify since I'm up two pawns.} 24... f5 25. Rxc8+ {24 minutes left.} 25...
Nxc8 26. e5 {22 minutes left. I wanted to make trouble for his queen but here
I am removing the defender from that bishop.} 26... Qd8 27. Rb1 {20 minutes
left. As soon as I moved it I saw the bishop skewer and thought I had blown
it.} 27... f4 {My opponent saw it too.} 28. Qc4+ {The one move to save it. I
wish I could say I had planned this well ahead.} 28... Rd5 29. Rc1 {15:46
left.} 29... Bf7 {Here I saw a free knight and a queen exchange.} 30. Qxc8 {My
opponent resigned here.} 1-0
