Kibitzer's Corner
Oct-16-04  morphynoman2: No kibitzing for this wonderful game??

  Honza Cervenka: White's combination is fantastic. 22...Ncd3 23.Nxe7+! Kh8! 24.exf6! Rc2 25.Rd2 Qa7+ 26.Kh1 Bxg2+ (26...Qa8 27.Qg4!! with unavoidable mate.) 27.Kxg2 or 22...exf5 23.exf6 Bxf6 24.Bxf6 Ne4 (24...Nxc6 25.Rxf5 ) 25.Bxe4 cannot save black.

Later Vyzmanavin's play was not much accurate allowing Sorokin to resist quite long. For example, after 37.Be3! Ra2 38.f6 the game would have been over immediately.

  Honza Cervenka: And, of course, if 22...Nxc6, then 23.Qg4+ Kh8 24.exf6 Rg8 25.fxe7+ e5 26.Qh4 (threatening 27.Qf6+; 26...Rxe7 27.Qf6+ Rg7 28.Bxc6 Bxc6 29.Qxe7 ) 26...Nd7 27.Bxc6 Bxc6 28.Bxe5+ Nxe5 29.Qf6+ Rg7 30.Rd8+
Nov-25-04  offramp: I can hardly believe that he saw from move 21 to move 33 - but he must have done!
Nov-25-04  offramp: Doesn't 24.Ne7 win straight away?
Feb-11-05  aw1988: <offramp> Indeed it does.
Feb-18-11  acme: It doesn't. Black doesn't need to respond to Ne7. What if he continues with, say, Bxg2?
Feb-18-11  siggemannen: really sad... both of these guys are not alive anymore
Jun-20-11  Dr. J: 24 Ne7 fails against 24...fxe5 followed by ...Ne6. But not 24...Bxg2?? 25 Qg4
Aug-22-13  phil6875: <Dr.J> 24. Ne7 does win. There's no move 24...fxe5 for Black, do you mean 24...exf5? If so, 25. Rxf5 and Black has three possible moves 25...Bf3, 25...Ne6 and 25...Qa7 all losing.
Apr-23-15  FairyPromotion: This is a masterpiece that could have ended up being an even bigger one.

<offramp: Doesn't 24.Ne7 win straight away?>

24. Ne7! is completely winning, however the game continuation 24. Rf4!! is even stronger, as it forces mate. The main idea is to play Rh4, Qh5 and force mate on h7. Black's 24... e5 interfered with the idea, however it should have only changed the queens route. Sadly white slipped with 25. Rxd8?, and although his position was still winning, he had to work much harder to convert the full point.

What white saw probably was that after 25. Rh4 <Bxf6> (D) comes with tempo on the rook, and that after 26. Rh3 Bxc6 27. Qh5 black can play the clearance sacrifice 27... Bh4 in order to play f6 and defend laterally with the rook, and if instead white plays 28. f6 himself, then 28... Bxg2 29 Rxh4 Be4, there is no mate and white is down 2 minor pieces.

However after 25. Rh4 Bxf6:

White has <26. Bxe5!> pinning black's bishop, 26 ... Bxe5 27. Qxe5+ f6 (... Kg8 28. Rg4#) 28. Qxc7 with mate coming on h7.

After 24. Rf4 another move that changes the dynamics of the mate (and thus is worth analyzing) is 24... Bxc6:

Here white forces mate by 25. Qg4 Rg8 26. Qh3 Bxf6 (... Bxg2? 27. Qxh7!) 27. Bxf6+ Rg7 28. Qh6 Qg8 29. Rg4, with the option for black to pick his poison.

Black's other try here might be 26... exf5 stopping immediate Qh6 or Qxh7 ideas, but it is properly met with 27. Rh4 and all that black can do to resist for a few moves more is the sad 27... Rg7.

Couldn't white win with 27.Rxh7+?

Apr-24-15  FairyPromotion: <offramp: Couldn't white win with 27.Rxh7+?>

Not really. With the black rook on e8, f8, or g8 white can indeed mate with Rxh7, but here the black king has the e8 square to escape. If white tries to stalemate the king with a quite move, like 27. Rxh7 Kxh7 28. Qh5+ Kg8 <29. Qh6>, black has 29... Ne6, and white is simply down too much material.

Apr-24-15  offramp: <FairyPromotion>, yes, thank you.

As you say, there is an escape route via e8 for black's king. If I was playing the game I would have played 27.Rxh7+ which is bloody poor! I must try harder.
