  sisyphus: Can somebody say what's going on here? I mean, the second piece sac (16. Ne6+) is a beautiful shot, but 9.Nd5!? I don't play closed Sicilians, so all this is incomprehensible to me.
Dec-29-08   Andrew Chapman: 10..Bc8 was a surprise to me and gives a remarkable position. Was it to prevent Qg5 after Re1, after which maybe Black gets tied up on the King side?

Wow, what an *incredible* game by Vallejo.

Dec-29-08   fgh: Very nice. The sacrifices are not so difficult to understand on a intellectual level, but they are difficult to calculate correctly and even find them on the board.

  chancho: Vallejo le quito el pellejo a Nepo en esta partida..
Dec-30-08   Tacitus: Reminds me of a Morphy game-after ten moves Black has all his pieces on their original squares.
Dec-30-08   anandrulez: Incredible , surely some preperation in the opening but hats off to the way the attack was carried ! It was almost like "hell i wont move my pieces back in the sicilian" approach from white ...would have been interesting to see topa ivanch etc play this line ...is this a novelty ?
Dec-30-08   SniperOnG7: 25 moves - qualifies for a miniature too.

One of the year's best miniatures, along with Akopian vs Vachier-Lagrave Dresden 2008 if that game was short enough for a miniature.

Dec-30-08   SniperOnG7: Thanks for that <notyetagm>. Since the Olympiads took place around the time I had my exams, I was not able to follow it. What a jem Akopian vs M Vachier Lagrave, 2008 was indeed. Sicilian sacrifices galore just like this one.
Dec-30-08   SufferingBruin: Can someone explain black's 12th move?

12. ... Kf8.

Thanks in advance...

  chancho: <SufferingBruin> I could be wrong, but 12...Kf8 was probably played to step out of the pin.

After 25.Qxe6+:

A) 25.Qxe6+ Kd8 26.Qe7+ Kc8 27.Bb7#

B) 25.Qxe6+ Kf8 26.Qe7+ Kg8 27.Bd5+! Nxd5

  Domdaniel: It's not really a closed Sicilian -- it's the same flexible 2.Nc3 that Arno Nickel used in the 2nd game vs World/chessgames. I won't comment further on it as that game is still in progress, but it's a very fashionable idea right now: play 2.Nc3 with the option of an old-fashioned Spassky-style Closed Sicilian, or Nge2 and d4 transposing to an Open line (or even a Grand Prix with f4).

As GM Alex Baburin points out in his notes for Chess Today (he annotated this game in the December 30th edition), White has plenty of waiting moves like g3 and Bg2, while Black quickly runs out of them unless he is willing to play ...Nc6. Which may allow transposition to a Sicilian line he wouldn't have wanted to play.

Black's other option is an early ...e5, which prevents d4 but isn't to everyone's taste.

9.Nd5 is a novelty, but both players here seem to have prepared for it. Baburin even suggests that Vallejo played 12.c4!? on purpose to get out of Nepo's prep -- c4 is neither the most obvious move nor the one suggested by computers. And he was rewarded at once with the very dubious ...Kf8 --- 12...bxc3 is better, leaving black with a fighting chance. After ...Kf8 he's already in serious trouble.

  Domdaniel: Baburin on 10...Bc8:

"I gave the position after 9.Nd5!? to
Rybka and left it running for a long
time - and this [...Bc8] is what it came up with too! Morozevich used to say in such cases: "Are we setting up pieces for a new game?!"

Obviously, the idea of 10...Bc8 is to
cover the f5-square, but it's hard to
believe that Black can play chess like
this and get away with it! For 2 points White has the following:

1. Huge lead in development.
2. Open e-file.
3. Powerful pawn on d5, which
helps the knight's invasion to
c6.
4. Target on b4."
