  Eyal: 30...Ne6 is an instructive example that a natural-looking move ("centralizing" the knight, attacking White's bishop and d4, indirectly protecting d5 - 31.Nxd5?? loses to 31...Bc6) isn't always a good one. Instead, after an immediate 30...Rh8! Black could have countered 31.Re3 with 31...Rh4 32.Rg3 Rg4; whereas in the game, after 31.Qf2 Rh8? (here 31...Bc6 or Nxf4 were necessary) 32.Re3, it turns out that White has gained a crucial tempo with his 31st move defending the bishop and denying the h4 square from the black rook, while Black's 'd' pawn is left unprotected.

Yep, but for his reputation, it would be good not to be involved with Mister SD anymore!

Nov-30-07  cotdt: Topalov and Danialov are Cheparinov's seconds, so quitting his association with them is not an option, lest he trains himself.

  egilarne: Cheparinov is calculated to be around 2704 FIDE Elo before this game - has gained 34 points the last months - which means his performances has been even better.

  JointheArmy: I always thought the theory behind 9. c4 is flawed.

In Art of Attack, Vladimir Vukovic says <[9.c4] releases tension in the center and so creates the one precondition which White still lacked before he could embark on an attack against the enemy king. Maroczy, a great expert on defence, is playing here under the influence of thinking of the old school which paid insufficent attention to the problems in the center. In the Orthodox Defence to the Queens' Gambit, resolving the central tension by ...c4 generally gives White a powerful attack on the king, for a counter attack based on a pawn majority on the wing is much slower than that which takes place in the centre (Vukovic 309).>

Nov-30-07  Shams: <JoinTheArmy> I totally agree, although we must remember this is Mamedyarov who made this move. He must have had some plan in mind.

I really don't like 14...Nb6 pulling the knight to a famously inferior square. I like f8 for the knight, then perhaps e6 pressuring d4.

Nov-30-07  badest: <chancho: Cheparinov has the potential to be an elite player.> Some definition of "elite" you must have :)

What, are only the top 10 = elite?

Nov-30-07  chessmoron: FIDE rating list. Top 10. What do expect?

Well done! Let me add that 32.Re3! is sound and the true refutation of 31...Rh8?. But not 32.Nxd5?! Bc6 completely unclear. I think Mamedyarov saw the complications after 32.Nxd5?! but understimated 32.Re3!.

Great reference.

Maybe Mamedyarov was pleased about this previous ... c4 effort and thought he'd try to play around with it more in a different setting. But you win some, you lose some!
