Aug-11-13  bubuli55: Congratz Wesley! Nice game :)
Aug-11-13  bubuli55: I think Wesley had calculated the 34.Rxf6 to the end. 12 moves

  OhioChessFan: <bubulli> I would agree he had it all worked out. Black had a few other options but So was in total control. Black was positionally lost after 22. Qxd5 and the rest of the game was just winning a won position. Strange how Black didn't play Rd8 until his 37th move when it was repeatedly the best move on the board.
Aug-11-13  SugarDom: Ipatov is melting under the spotlight. Rookie. He will be more relax on the next round, Wesley will be careful as usual.
Aug-11-13  lakers4sho: Was 19...Nd5 simply a tactical oversight by Ipatov or was there a reason for giving up the pawn? The reason was pretty much a lost endgame for Black.
Aug-11-13  SugarDom: I'm a 1700 patzer, and it's an obvious blunder. hehe
Aug-11-13  lakers4sho: nerves? time pressure?
Aug-11-13  csmath: Every time Petroff is defeated it is a good thing.

This is actually very powerful game by So. Clearly

19. f5! is a move that blows away whole variation Ipatov played. There is really no satisfactory defence against that move.

Ipatov missed

17. ...c5! as active response. This is often the case with Petroff players - they just do not like to play active chess. It is somewhat counterintuitive since it seems to open position to white's bishop pair but black rooks are faster.

17. ...c5!
18. a4 [dxc5? Nxc5 19. Bd5? Rc8 and Re8 ] c4
19. Ba2 a6

and given how exposed white king is it will not be easy for white to regroup.

I was wondering what the heck was black doing with

32....Kh4?!, 33. ...g5?, 34. ...Rf6? is just poorly calculated countergame.

Nice and courageous game by So. Ipatov is a up-and-coming new force in Ukraine and he will get better than this.

  OhioChessFan: <19...gxf5> 20. gxf5 Nd5 would have been better, though I think Black might be strategically lost. In the game continuation, the Queen capturing d5 with check is what made the entire combination work eg 19...gxf5 20. gxf5 Nd5 21. Bxd5 cxd5 22. Qxd5 Bh2+ 0-1
Aug-11-13  csmath: Even though the position after 27 moves is very difficult for black to play he could have tried 28. ... Rf6!? to try to bring king back in center. Probably not enough and too late but more resilient than his 32-33-34 plan.
Aug-12-13  epistle: What's the point of being more resilient if it will also lead to defeat?

Aug-12-13  LIFE Master AJ: Nice game by So ...
Aug-12-13  Libispusher: With h3, g4 and f4 after castling proper, you know right from the opening that white meant business.

Black was well ahead on time at the onset but may have ran right smack into a counter prep. The position after 15.f4 looked very strong for white which puts the integrity of the variation stemming from 11…Bg4 into question.

If 19…gxf5, white intended to play 20.gxf5.

Aug-12-13  epistle: why is this game "nice" only? I like csmath. He added "powerful" and "courageous."
Aug-12-13  LIFE Master AJ: <epistle> Actually, this game just about blew me away. However, I refrained from getting too wordy or lavishing a lot of praise on the game, as the trolls that seem to run this site, always try to make a big deal out of everything. (But only when I say it, they don't seem to bother attacking anyone else like this.)

Therefore, I was trying to remain "low-key." Fair enough?

Aug-12-13  epistle: My hats off to you LIFE MASTER AJ! Trolls are worthless creatures. Don't let them affect you or your chess.
Aug-12-13  iking: good prep by Wes ....
Aug-12-13  LIFE Master AJ: <epistle> Thanks for the nice words ... I hope you have a good week. [And enjoy all the good chess on this site, and even I learn must learn to do this ... comment on the game(s), but ignore the trolls.]
Aug-16-13  visayanbraindoctor: Good opening preparation, and an aggressive and sound middle game, no blunders. GM So impresses.
Oct-08-13  jphamlore: Is it possible that Wesley So's familiarity with the Exchange Grunfeld gave him a clear roadmap how to play this variation of the Petroff? It seems to me White early on achieved a pawn structure and piece placement with all the benefits of the Exchange Grunfeld and none of the downsides, with a crystal clear plan of eventually obtaining the passed d pawn characteristic of White's plans in the Exchange Grunfeld.
