1. e4 {I had prepared for French, but didn't know which variation she would
play.} e6 2. d4 d5 3. Nd2 Nf6 4. e5 Nfd7 5. Bd3 c5 6. c3 Nc6 7. Ngf3 cxd4 8.
cxd4 f6 {This was a surprise. I don't have much experience with
this line, but I knew the plan was to prevent ...e5.} 9. exf6 Nxf6 10. O-O Bd6
11. Re1 O-O 12. b3 Bd7 13. Bb2 {Although the e-pawn will never
advance, the next challenge became: what now? With a dark bishop that is not
immediately active and a knight without any squares, I needed to untangle.} Qb6
14. Rc1 Rac8 15. Bb1 Rce8 16. Qe2 {I couldn't see a way to open
the queen through the diagonal, so I took the long way around. Fortunately
this position did not involve counting tempi.} Bc8 {I continue to have no idea
why she played this move.} 17. Qe3 Rf7 18. Ng5 {I probably shouldn't have
bothered, considering I wasn't willing to sac after ...h6.} Rfe7 19. Ndf3 h6
20. Bg6 $2 {My one serious mistake of the game. Neither of us saw
21...Bf4, winning material. At this point, we had each used up too much clock
time for only 20 moves, but I had a comfortable advantage with 33 minutes to
21 minutes.} (20. Nh3 $142) 20... hxg5 21. Bxe8 $2 {A continuation of my 20.
Bg6 mistake.} Rxe8 $2 $17 (21... Bf4 $142 $19 {saving the Pg5 before
recpturing on e8.}) 22. Qxg5 Rf8 23. Qh4 Nh7 24. Rc2 {I wanted to
lift a rook to the 3rd rank, but was stopped by ...Bb4 or ...Bf4. I hoped she
would try to defend against me doubling my rooks so that I could play Re3.} Rf4
25. Qh3 Qd8 26. Ne5 Nxe5 {We're now into time trouble - I have 11 minutes, and
she has 8 minutes.} (26... Nxd4 27. Bxd4 Rxd4 28. Qc3 Bxe5 29. Rxe5) 27. dxe5
Bb4 28. Rec1 {I originally wasn't planning on doubling on the c-file, but this
seemed like a good opportunity.} Bd7 29. Qe3 Re4 30. Qxa7 Bc6 31. Bd4 {I had wanted to bring another piece into play in the center while stopping
...d4, but I missed ... Qh4 by Black. But she is now in serious time trouble:
I have 9 minutes, and she has 2 minutes.} Qh4 32. a3 {I didn't want to move my
bishop back to allow ...d4 with all her pieces surrounding my king, so I gave
the pawn back.} Rxd4 33. axb4 Rxb4 34. Rc3 {...d4 now loses to Qb8+ Nf8, Rxc6
bxc6, Qxb4.} Rg4 35. Qb8+ Nf8 36. Rf3 Qe7 37. h3 Rg5 38. g4 {Nullifying the Bishop/Rook g2-attack. With her queen and knight tied up near
her king, she doesn't have enough pieces to take advantage of the weakened
pawns. We're now each in serious time trouble: I have 2 minutes, and she has 1
minute, and we played the rest of the game on increments.} d4 39. Rf4 $2 (39.
Rxf8+ $1 {I missed this Rxf8 computer tactic to trap her pieces with my pawns.}
Qxf8 40. Qxf8+ Kxf8 41. f4 Rg6 42. g5 {and Black's R will never get out,
leaving White effectively up an exchange on the rest of the board.}) 39... d3
$2 ({I missed this ...Rf5 tactic by Black, winning a pawn, and stopping my
attack.} 39... Rf5 40. gxf5 (40. Rxf5 exf5 41. Qd6 Qg5) 40... Qg5+ 41. Kf1 Bg2+
42. Ke1 Qxf4 43. Rc8 Qxf5) 40. Rd1 Qc5 41. b4 Qe7 42. Rxd3 Bd5 $4 {Game-losing, allowing the rook to penetrate on the
a-file instead.} ({editor -} 42... Be8 43. Rd8 Bf7 44. Rc4 $18 {bringing
another major to the back rank.}) ({editor -} 42... Rf5 {The only move, but
good enough for equality, according to the computer:} 43. gxf5 Qg5+ {Only move.} 44. Rg4
$8 Qc1+ 45. Kh2 Qh1+ 46. Kg3 exf5 {Only move.} (46... Qg2+ $2 47. Kh4 Qxf2+ 48. Rdg3 $8
