Aug-13-13  John Abraham: This kid is pretty good
Aug-13-13  fgh: Or, perhaps, Radjabov is pretty bad... :-)
Aug-13-13  John Abraham: <fgh> I was talking about KID, the King's Indian Defense ;p
Aug-13-13  Everett: I will not be surprised if the venerable and, IMHO, best 9..Ne8 resurfaces as the right answer to the Bayonet KID.

  hedgeh0g: 11...Nf4?! seems dubious to me as it appears to simply walk into an inferior ending where White has a very powerful passed e-pawn. 11...Nf6 is a more principled continuation, in my opinion, maintaining the tension. However, I believe the real cause of Black's problems was the ill-advised 13...h6?, severely compromising his kingside after the coming exchanges. After 13...Bf6!, Black could reach the same position as in the game, only with the pawn still on h7, denying White some of the play he was able to generate in the game.

I'm not entirely sure why Radjabov would willingly enter this line. Perhaps he wanted to steer the game into more uncharted territory, hoping to outplay his lower-rated opponent, but I can't see Black doing much better than grovelling for a draw in these lines.

  perfidious: <hedgeh0g>: While being thoroughly unprincipled, I agree: 11....Nf6 is likely stronger and here is an example from Radjabov's early praxis: A Szeberenyi vs Radjabov, 2000.

The final position is curious and evokes memories of the end from O Neikirch vs Botvinnik, 1960.

Nasty business at the finish here-how do I shtup thee? Let me count the ways.

  Whitehat1963: Time for Radjabov to take his KID, go home, and put it away for a while.
Sep-18-16  Albanius: In the final position, if 32..Rff8!?
hoping to mate after 33 ef8/Q Rxe1+
W has
33 exf8/N+! Kg8
34 Bc4+ Kxf8
35 Qh8#
However, after 33 exf8/Q Rxe1+
34 Qxe1+ Qf1 would avoid mate, staying a piece up. But the underpromotion mates by force.

It doesn't if Black recaptures with the other rook.

Feb-24-21  Gaito: This was a rapid game, maybe 30 minutes for the whole game for each player, or perhaps 20 minutes with some increment. It is not clear if there was some increment. At any rate, by the end of the game there were a few terrible blunders and oversights, so that it is likely that both players were very pressed by the clock, and that would account for the mistakes. Consider the following position:

27...Rf6?? was an awful blunder (Zeitnot?) losing outrigt.

27...Rf5 was in order, for instance: 28.e7 Re8 29.a4 Qb4 30.Bc4+ Kh7 31.Qe2 Qxa4 32.Bd3 Qd7 33.Bxf5 gxf5 34.Qe5 Kg6 35.h3 Kf7 36.Rf1 Rxe7 37.Rxf5+ Kg8 (see diagram below):

This position is a dead draw.

Feb-24-21  Gaito: But two moves later it was White's turn to blunder (returning the favor). Take a look at this diagram:

White played 29.Qd5+?? throwing away a winning position. Correct was 29.a4! seizing control of the important square b5 for his bishop. For example: 29.a4! Qb4 30.Bc4+ Kg7 31.Qe2 (White's a4 pawn is indirectly defended by the threat Bb5) Rf5 32.Bb5 Rxb5 (forced) 33.axb5 a4 34.h3 a3 35.Qe5+ Kh7 36.Re4 Qb2 37.Qxb2 axb2 38.Rb4 Rxe7 39.Kh2 (see diagram below):

This ending is technically won by White owing to the favorable position of his rook behind his passed pawn. It is a very easy winning endgame.

Feb-24-21  Gaito: The final part of this game was a comedy of mistakes, by both players: Black blundered on his 27th turn, then White blundered on his 29th turn, and finally Black blundered again on his 30th turn. Since both players are well-known grandmasters, perhaps the only explanation for so many mistakes is that they were both pressed by the clock. Let us take a look at the following diagram:

Radjabov played 30...Qf2??, which is a terrible oversight, and lost quickly after 31.Bb5 Kh7 32.Qa1. From the diagram Black ought to have played 30...Qb8! forcing a drawish ending. For example: 31.Qxb8 Rxf1+ 32.Rxf1 Rxb8 33.Re1 Re8 34.Re5 Kf6 35.Rxa5 Rxe7 (winning an important tempo on account of the threat of mate) 36.Kg1 Re2 (see diagram):

This is an elementary text-book draw.
