Feb-17-14  Conrad93: Wow, casstling on the queenside and then destroying your own kingside for an advantage.

Balls of steel.

Feb-17-14  Conrad93: No comments on this great game?
Feb-17-14  mrbasso: I can't comment anymore because I'm bussy shaking my head... Why do you consider this a great game?
Feb-17-14  gaviero55: Another really nice game from Jobava! Just at face value 13...b5 seems premature. 15.d4 & 16.Nc5 are effective replies. 29.f4 is surprising, perhaps the N shouldn't be captured? Black's center collapses. Dubov avoids 30...Bg7 because of 31.f5. Fertile play from Jobava again.

  tamar: 4 h4 h5 is a humorous interlude. Jobava had played an early h4-h5-Rxh5 in his previous White game Jobava vs B Savchenko, 2014 1-0, and Dubov wants no part of it.
Feb-18-14  mrbasso: 13...b5 was premature but Jobava plays it badly; ends up in a worse position. Then youngster Dubov blundered beginning with 33...Rc8?? several times in a row. After 33...Rd8 white is in trouble because two pawns for a piece is usually not so great and this is no exception although some swindle chances remain.

  WannaBe: After 35...Nxe5, black is up 2 minors. And after 36. Qd5+ black have the option of 36...Nf7 or move the king.

I know I am not a great player, what caused the resignation?

Feb-21-14  Shams: <WannaBe> Easy lines first-- Black resigned in the final position because White is trivially winning after either 37...Kxf7 38.Nxe5+ Ke6 39.Rxc8 or 37...Nxf7 38.Rxc8 (∆ Rxf8), in both cases emerging with a big material edge and having the great advantage of possessing the only rook on the board in an endgame.

As for your earlier deviations:

i) 36...Nf7 37.Nf6+ Kh8 38.Nxe8 Rxc1 39.Qxb5 (not 39.Qxf7?? Rc2+ allowing a perpetual) and White wins easily due to a material edge and a host of favorable positional features.

ii) 36...Kg7/h8 (36...Kh7? 37.Nf6+ transposes to the above line) is a bit trickier. The best I can see is 37.Nf6 Qf7 38.Rxc8 Qxd5 39.exd5 with a complicated position. If I can't find anything better or convince myself this is a win, I'll feed it to Shredder later.

Feb-26-14  KingP: Well I think the piece sac was a bit speculative, but white has compensation in the form of two pawns and the N on e7 is badly placed. I think he played 30. ...Bf8 because after Bg7 he was afraid of 31. f5! and a piece has to move again. But I think he should have played Bg7 31.f5 and then maybe d5! to sac back a piece and play d4 and/or Nd6 with counterplay. For instance Bg7 31.f5 d5 32.f6 d4 and black is not worse.
