  Eyal: <Ulhumbrus: On 18...Qb3 19 Be2 Qc3+ 20 Qxc3 Rxc3 21 a4 Ra3 22 Bd1 Bf5 23 Nd4 Bd3 24 Kd2 Rc8> You just don't give up, do you?:-) That loses to 25.Be7 (which is a strong threat after Kd2, I forgot to mention that) Rac3 26.Nc6.
Jan-25-07  Hesam7: <<aragorn69>: Interesting analysis by Topalov. He obviously is still hiding a lot of his preparation. That's probably why he does not comment on 15.-Nxc5. He avoids to have to say what he thinks would be Black's best move at this point.>

I think that is right.

<<aragorn69>: In conclusion: 16.-Be6 may be the losing move, unless some better moves can be suggested in the b) variations.>

What is the alternative? Topalov suggests 16...Bd7, but what happens after 17.Qxd5 Be6 (this looks forced) 18.Qd2:

18...Qxa3 19.Bd3 Qa1 20.Qd1 Qc3 21.Ke2 Bc4 22.Bxc4 Qxc4 23.Qd3 Qa2 24.Nd2 Qe6 25.f3 a4 26.Rc1 a3 27.Kf2 a2 28.Ra1 Rfe8 29.Kg1 [+0.93 @ depth 18]

  Eyal: <Hesam7> Actually, in the line that you give, after 28.Ra1:

Black wins by 28...Qe5, forking rook and bishop.

Jan-26-07  Ulhumbrus: <Eyal> The possibility of Be7 suggests ths following improvement to begin with: 18...Qb3 19 Be2 Qc3+ 20 Qxc3 Rxc3 21 a4 Ra3 22 Bd1 Bf5 23 Nd4 Bd3 24 Kd2 and now instead of 24...Rc8 at once, 24...Bg6 removes the B from attack and clears d3 for ...Rd3+

Jan-26-07  Ulhumbrus: <Eyal> Another alternative is ...Bb1 instead of ...Bg6 as follows: 18...Qb3 19 Be2 Qc3+ 20 Qxc3 Rxc3 21 a4 Ra3 22 Bd1 Bf5 23 Nd4 Bd3 24 Kd2 Bb1

Jan-30-07  jrman: Black is winning or at least draws after Nxc5. Here follows my analysis of Topalovs short suggestion...

15. b5 Nxc5 Sacrifices material
16. c6 Nc5

16. Qxc5 Be6 The loosing move
16... Bd7 The winning move

17. Qxd5 Be6
18. Qd2 (Best move according to Fritz)
(18. Qd1,Qd3,Qd4 must be analyzed separately)

(18.Qxb7 doesnt work... Rfb8 19. Qe7 Rc8)

18... Qxa3
19. Be2 Qa1+
20. Bd1 a4
21. O-O a3
22. Be7 Rfc8
23. Bb3 Qb2
24. Bxe6 Qxd2
25. Nxd2 fxe6
... and blacks just winning

  Eyal: <jrman: Black is winning or at least draws after Nxc5> So, if White doesn't have anything better to do in the line above, he can play 20.Qd1 instead of Bd1, and then Black doesn't have anything better than a draw by perpetual after 20...Qc3+ 21.Qd2 Qa1+ etc.
Jan-31-07  square dance: <jrman> try 19.Bd3 in your line instead. rybka gives it +0.48 at 20 ply. 19.Be2 is 0.00, which would indicate the draw by perp that <eyal> mentioned.

  Eyal: <square dance: <jrman> try 19.Bd3 in your line instead.> Yes, I see the basic idea: 19...Qa1+ 20.Qd1 Qc3+ 21.Ke2.
Jan-31-07  square dance: <eyal> rybka seems to like 19...f6 20.Bf4 g5 etc. but the idea you mention is the next line, which is at +0.73 at 19 ply.
Mar-08-07  AAAAron: I think Carlsen miscalculated 15. ....Nxc5, exchanging his knight for a pawn with no solid counterplay. Who does Carlson think he is, Kasparov? Now just out of curiosity, what would of happened if Carlsen played 23. Rcc1??? <Anyone>?
Mar-12-07  AAAAron: <anyone>?

  tpstar: There were several posts during the live event suggesting 23 ... Rcc1, and <aragorn69> reprinted Topalov's analysis concerning 23 ... Rcc1 24. Kd2 on 1/25/07. There's even a post about 26. Bb3?? Rcc1 0-1, versus 26. h4 1-0.

Just click on "Earlier Kibitzing" to read them.

Mar-12-07  AAAAron: Thanks, tpstar! I'll check it out.
Aug-26-07  adnol: Why the heck did black resign?
Aug-26-07  centercounter: White's pieces are well posted, and Bb3 looks like it's coming. At some point a5 looks like it will fall to White's dark-squared Bishop. Black is in poor position to defend his weaknesses and all White's potential weaknesses look solidly defended.

Ok, not resignable at the mortal level, but certainly unpleasant to look at considering you're facing one of only 4 in history to have passed 2800 FIDE (not counting ChessMetrics).

Oct-26-07  GSankarN: why did carlsen (black) resign?
Oct-26-07  pawnofdoom: Probably because Topalov's two minor pieces are much more powerful than Carlsen's single rook in a position like this which only has one file that's completely open. Not only that, black has an isolated pawn. I wouldn't have resigned here if I were Carlsen, because he can obviously play on and have tiny winning chances.
Nov-03-07  GSankarN: why the heck did black-carlsen resign?
Nov-03-07  stukkenjager: Maybe it was a bit early to resign, but the position is very difficult for black. a sample line 26... ♖a3 27.b6 h5 28.♗c7 g6 29.g3 ♖c1 30.♗b3 ♖aa1 31.♖xc1 ♖xc1+ 32.♔g2 ♔g7 33.e4 dxe4 34.♗xf7 ♔xf7 35.♘b3 ♖c2 36.♘xa5 e3 37.♔f1 ♖xf2+ 38.♔e1 ♖b2 39.♘xb7 game over

May-05-09  walker: I am not good enough to understand this game:(
May-05-09  WhiteRook48: 2 pieces for a rook. Carlsen may have been hoping to win the h1-rook with 20...Rxc1+. Obviously, if that was his plan, 21 Bd1 ruined it
Oct-07-12  master of defence: Why Carlsen sacrificed a knight by 17...Nxc5? There is a best move than it?
