Bg2 e5 3. d4 e4 4. c4 c6 5. Nc3 Nf6 6. Bg5 Be7 7. e3 Nbd7 8. Nge2 h6 9. Bxf6 Nxf6 10. O-O Bf5 11. cxd5 cxd5 12. Qb3 Qd7 13. Nf4 {Premature.} Rd8 14. Rac1 g5 15. Nfe2 h5 16. f3 exf3 17. Bxf3 h4 18. Rf2 Ng4 {BLack is trying to continue the attack even though White's defensive position is sound.} 19. Bxg4 Bxg4 20. e4 {! Black is now under pressure. 20 ... dxe4 would be mate!} Be6 (20... dxe4 {??} 21. Qxf7#) 21. e5 Rc8 {The pressure is off the center now and Black can break loose his pieces.} 22. Rcf1 Rc4 23. g4 {White attempts to take the pressure off his kingside by exchanging pawns but Black doesn't mind losing the weak f-pawn.} Bxg4 24. Rxf7 Bxe2 {!} 25. Nxe2 Qg4+ {!} 26. Kh1 Qe4+ {!? Black can take the Knight instead, but feared the consequences of lines such as 27 Rxe7+ Kxe7 28 Qxb7+ Ke8 29 Qf7+ Kd8 30 Qxd5+ Kc8 31 Qa8+ Kd7 32 Rf7+, etc. Other moves besides ... Kc8 would be equally bad. Black had actually tried to gain a move or two on the clock through a couple of checks but overlooked the interposition of the Queen by White.} (26... Qxe2 27. Rxe7+ Kxe7 28. Qxb7+ Ke8 29. Qf7+ Kd8 30. Qxd5+ Kc8 31. Qa8+ Kd7 32. Rf7+) 27. Qf3 {!} Qxf3+ 28. R1xf3 Rf8 29. Rxf8+ Bxf8 30. Rc3 Rc6 {Black wants to protect his isolated pawn if an exchange is made.} 31. Kg2 Kd7 32. a3 Rb6 33. Rc2 Rc6 34. Nc3 Rc4 35. Rd2 Ke6 36. Rd3 {! Black had been setting up to play ... Bxa3!} a6 37. Kf3 b5 38. Kg4 Be7 39. b4 Bd8 40. h3 { White now seems to have all the advantages -- good King position, protected passed pawn, and a Knight against a bad Bishop. Also, Black has both a backward and an isolated pawn. However, how to press this seemingly advantageous position is the question.} Bb6 41. Ne2 {?} (41. Kxg5 Rxd4 42. Rxd4 Bxd4 43. Nd1 Kxe5 44. Kxh4) 41... Rc2 {!} 42. Kf3 {At this point, Black had nine moves to make in five minutes, and also didn't like the looks of the position, so he offered a draw, which was declined. Glen felt his position was superior and figured the time element would help too. White should have played 41 Kxg5 instead of the text. Then 41 ... Rxd4 42 Rxd4 Bxd4 43 Nd1 Kxe5 44 Kxh4 would have left him a better game. 41 Ne2 (the text move) looks plausible but badly opened up White's position.} Kf5 43. Ke3 g4 44. hxg4+ Kxg4 45. Rd1 h3 46. Nf4 {46 Rg1+ looks better here although 46 ... Kh4 47 Kf3 h2 48 Rh1 Rxe2 49 Kxe2 Kg3 50 Kf1 Bxd4 51 e6 Bf6 leads to a Black in through zugzwang!} (46. Rg1+ Kh4 47. Kf3 (47. Rg8 Ra2 48. Nc3 Ra1 49. Rh8+ Kg3 50. Nxd5 Ba7 51. e6 $16) 47... h2 48. Rh1 Rxe2 49. Kxe2 Kg3 50. Kf1 Bxd4 51. e6 Bf6) 46... Rc3+ 47. Nd3 {White was playing Black's time trouble here and may have missed the best line. } h2 48. Ke2 Bxd4 49. Nf2+ Bxf2 50. Kxf2 Rc2+ 51. Ke3 Kg3 52. e6 Rc6 53. Kd4 Rxe6 54. Kc5 Kg2 {A very complicated endgame with many possibilities on both sides.} 0-1
