Kibitzer's Corner
Oct-29-05  iron maiden: Ivanchuk completely dominated here. 16. e5! is a nice shot, since Black can't take the pawn without allowing White to open up the file to the bishop on d7 and win a piece.
Oct-30-05  Johnox: Yes, but an interesting fight would resulted if Black continue with 16..a6 instead of 16..Nh7.

  acirce: Wouldn't 23..Bc6 or 23..gxf5 have worked much better than just heading for a much worse endgame?
Oct-30-05  Averageguy: <acirce> After 23...gxf5 I think that 24.Nd5 wins, threatening the Rc7 and Ne7+. If 24...Rxc2+ 25.Kb1 and if the queen moves to stop Ne7+ then the Rc2 hangs, and if 25...Kh7/8 than 26.Rxh5+ Kg8 27.Ne7# is Anastasia's mate. If 25...Re8 white wins with 26.Nf6+ Bxf6 27.Qxf6 threatening Rxh5 and Rh8#, if 27...Re6 then 28.Rxh5 Rxf6 29.gxf6 and Rdh1 and Rh8# looks unstoppble. After 23...Bc6 then I think that white can play 24.f6 Bh8 25.Rh4, I think that white's attack will pull through.

  acirce: <Averageguy> 23..gxf5 24.Nd5 Rxc2+ 25.Kb1 Re8 26.Nf6+ Bxf6 27.Qxf6 looks good but is too slow, Black easily defends and wins with moves like 27..Rc6. Your line after 23..Bc6 might be interesting but also looks too slow, I'll look closer at it later.
Oct-30-05  Averageguy: <acirce> Hm, I posted<if 27...Re6 then 28.Rxh5 Rxf6 29.gxf6 and Rdh1 and Rh8# looks unstoppble.>27...Rc6 seems to lose the same way as 27...Re6.

  acirce: I apologize for my sloppy reading. But 27..Re6 28.Rxh5 Rxf6 29.gxf6 and for example 29..Rf2 (there are many other moves), then 30.Rh1 Qc2+ mates.
Oct-30-05  Averageguy: <acirce>You seem right about my analysis, ah well.
Oct-30-05  ConLaMismaMano: Once this game ended Felgaer said that after move 16 he improvised and the cause of many of his blunders were because he had to make 20 moves within 10 minutes. On the other hand, Ivanchuk said that Felgaer had good chances if he had played 23...gxf5 or 27...h4. He also added that his sac on d6 (19.Nxd6) was not very clear.
Oct-30-05  Hesam7: After 27... h4 Fruit gives:

28. f6 Bh8 29. Rd2 h3 30. Rh2 Bg2 31. e6 fxe6 32. Rxe6 Ra8 33. Kd2 a5 34. Re3 Rd8 35. Ke2 Rc8 36. c4 a4 37. bxa4 Rxc4 38. Re8 Kh7 39. a5 Rc2 40. Ke3 Rc3 41. Kd2 Rc5 42. Re7 Kg8 (eval: +0.76)

Nov-03-05  Hesam7: It seems that Chucky's sac was a sound one. Here is Fruit's analysis after 19. Nxd6:

19... Nxb3 20. axb3 exd6 21. Qxd6 Rc7 22. g4 Qc8 23. gxh5 Bc6 24. Rh4 gxh5 25. Qd3 Rd7 26. Qe2 Rxd1 27. Nxd1 Rd8 28. Ne3 Be4 29. Rxh5 Bg6 30. Rh1 Be4 (eval : +0.54)
