Kibitzer's Corner
< Earlier Kibitzing  · PAGE 7 OF 7 ·  Later Kibitzing>
Jan-26-11  polarmis: Here's the final version of Sergey Shipov's commentary on the game (with a few comments from his video round-up afterwards as well):

Jan-26-11  harish22: The game reveals the psychological and positional flaws in Carlsen's game.

Carlsen has won a lot of his games against the game's elite. Besides Kramnik, no other super GM has been able to handle him. Anand has lately been able to hold his own. But other established GM's have crumbled. This maybe due to their ego. But Carlsen seems to lose often when he plays with GM's his own age or younger to him. The current loss, coupled with loses to hammer, giri and his olympiad losses seem to confirm that. Anand was able to break away from players of this own generation. And that included some super GM's like Ivanchuck and Gelfand. Hope he is able to handle it.

The e4 pawn "sac" was probably done so that he could have opened his bishop pair against the king. But Carlsen never got going. Nepo was able to force the exchange of the bishop using the N on g6. Carlsen positional sense seems to have deserted him when he did not fully analyze the effect of that extra piece on black's kingside. One can assume from the length of the game that it was a tough game, but Carlsen was never in it and just fighting to stay along. Not impressive at all.

Jan-27-11  okba12: wherse myearly kibitzing about the penis of nepo visa vi this of smeet?
Jan-27-11  Ulhumbrus: 24 Bf3 concedes the counterpart of Black's powerful Queen's Bishop for a N and creates a weak pawn on f3. Black has a threat of 24...Ng3+ but the centralization 24 Qd4! may answer it.
Jan-27-11  kia0708: which move was decisive for Carlsen's loss ?
Jan-27-11  anandrulez: Very hard to say which was the decisive move , after Carlsen declining 18 qd4 draw by rep , He became slightly worse and then he was always striving to =lize in the middle game , after Qe8 he was like -1.0 and then with the Knight in center it looked difficult to hold for Magnus . I didnt analyse too much on this game . Maybe some one can enlighten .
Jan-27-11  Kazzak: .22. Nxe7

Up until then he might have fought for a draw?

Jan-27-11  anandrulez: 41.Re3 was a blunder I read in Shipov's commentary I guess
Jan-27-11  fisayo123: This is now one of Nepo's 'notable games'........nice!

  Domdaniel: <Kazzak> -- < I wonder why BobCrisp asks this of every game that is marked <Uncommon Opening>?>

Because the last time I answered this question, I said that nobody would have to ask it again.

He's proving me wrong. A tad childishly, true, but he didn't have many options.

Another couple of repetitions and his query becomes a *ten bob note*.

Jan-27-11  Kazzak: I was joking too.

  Domdaniel: *Ian Nepomniachtchi* forked his opponents in Beijing, making him *China Tine Champion*.
Jan-27-11  Eyal: <24 Bf3 concedes the counterpart of Black's powerful Queen's Bishop for a N and creates a weak pawn on f3. Black has a threat of 24...Ng3+ but the centralization 24 Qd4! may answer it.>

The centralization 24 Qd4?? actually loses immediately: 24...Ng3+! 25.hxg3 (25.Kg1 Nfg5) Nxg2 winning Be3 or Re1. Other attempts to preserve the bishop pair would fail as well, e.g. 24.Nd4 Ng5! or 24.Bd3? Nxg2! 25.Kxg2 Ra4!! 26.Qxa4 Nc3+ (lines pointed out by Shipov).

Both 23...Nh4! and 25...Qd7!! (removing the pin on the e-file, preparing Ra4 and then Qg4) were really star moves by Nepomniachtchi, and he had to see them quite in advance, because they're necessary to justify his previous aggressive play. For example, 25...Nf6? just loses to 26.Bg5 Qd7 27.Bxf6 gxf6 28.Qf4. Of course, the knight can't be taken on move 26, because after 26.fxe4 Ra4 White loses the queen or gets mated: 27.Qc3 Bxe4+ and next the queen comes to g4.

Jan-27-11  rapidcitychess: <Domdaniel> You can't be Chinese and use a fork!

In China, a royal fork is called a royal chopstick.

Jan-27-11  Jim Bartle: So if they're driving and there are two roads, it's called a chopstick in the road?
Jan-27-11  rapidcitychess: <JB> No. They say it in chinese. :)
Jan-28-11  Ulhumbrus: <The centralization 24 Qd4?? actually loses immediately: 24...Ng3+! 25.hxg3 (25.Kg1 Nfg5) Nxg2 winning Be3 or Re1.> This suggests that the attack 23..Nh4 is a sound attack based upon a positional advantage, in which case it will probably win against any defence. Looking at the either side's state of development, most of Black's pieces are placed better than their White counterparts, and this may add up to a winning advantage.
Jan-29-11  freeman8201: har har.... This is the same way Ian won back in 2003: in a BK vs RK endgame with pawns and colors reversed.
Aug-22-11  MartijnvanWingerden: I think that if white hadn't play 48.c4 he had a good chance too win. 48.Qe2 looks much better for me. Lets see what Tarrasch has to say.

It looks that Qe2 and Qf3 both loose too Qg4.

Sep-15-15  ajile: <outplayer: 25...Qd7 is a cool move. the knight can't be taken although i didn't see the entire variation.>

If 26.fxe4 Ra4!! is crushing. To avoid mate White has to lose his queen.

Analysis by Houdini :

1. = (0.00): 13...Ne5 14.Qd4 Nc6 15.Qd2 Ne5 16.Qd4 Nc6

Jun-20-19  Diana Fernanda: Well, good done, the tecnike of Ian Is level superior, congratulaciones
Jun-20-19  SChesshevsky: Was great technique. Pretty consistent throughout the game. I thought 33...Qc8 was maybe not first to consider but was really clever.

Black played 66...Rd7 and White resigned.
Nevertheless, according to the powerful engine Stockfish 14, Black had a forced mate in 20 moves after 66...Kg4!

Just out of curiosity, it would be interesting to see how the engine achieves mate in exactly twenty one moves from this position playing against itself: So let us see. If it is true what SF14 announces, then mate must be delivered on move 87. Off we go:

66...Kg4 67.h6 (the pawn was lost anyway) Rd2+ 68.Kg1 Kg3 69.Kf1 (only move except for Bh4+ after which mate would be achieved sooner) gxh6 70.Bb4 Rd5 71. Ke2 Kg2 72.Bc3 Rd6 73.Ke3 h5 74.Kf4 h4 75.Be5 Rg6 76.Kf5

76...Rg3! (mate in 12) 77.Bd6 h3 78.Ke4 h2 79.Bxg3 Kxg3 80.Kd4 Kf4 81.Kd5 h1=Q+ 82.Kd4 Qc6! (instructive for beginners) 83.Kd3 Qc5! (notice that the quickest way to checkmate a lone king with queen and king is by placing the queen in such a square that if it were a knight it would be check) 84.Kd2 Ke4 85.Ke2 Qc2+ 86.Kf1 Kf3 and mate next move.
