  wordfunph: as recounted by GM Wolff from his book Wolff! The American Grandmaster Series..

<We played this game in the last round to decide first place. At one point, after making my move, I got up to stretch my legs and say hello to a few friends who had come to watch. Rustam (Gata's father) intercepted me and told me, "No talk, just play." The look on his face and his tone of voice left no doubt that he was threatening me. Never mind that it is normal to talk briefly to people about non-chess related matters, and that he had no right to disturb me in any way! Unfortunately, it was a Swiss tournament with scant arbitration, and by the time I could reach an arbiter, I had been distracted for over ten minutes. (By the way, when I was back at my board, Rustam actually physically threatened one of my friends! I am glad at least that I did not know this during the game). Gata is a very strong chessplayer and deserved this victory on the merits of his play. Yet he and his father also seem to have no compunctions about using "non-chess" tactics to compete. A strange side-note: After he had won this game, and thus tied for first, they still wanted to make a formal complaint against me for wanting to say hello to my friends, which I repeat is completely normal behavior at a chess tournament! Well, I will always remember this game, that's for sure...>

  chancho: <"I am envious that Gata Kamsky gets so much attention and money, It makes me angry.

It makes everyone here angry."

~Patrick Wolff>

Aug-21-13  JoergWalter: <chanco>w ould Wolff be happier if Kamsky got less attention and more money? really, what are these kind of statements good for?
Aug-21-13  Shams: <Joerg> Consider the anecdote <wordfunph> relates and I think you have a large part of your answer. Kamsky's father was such an oppressive force that resentment was only natural. Were it otherwise, well, Wolff knows how the world works: the stars feast while others fight for crumbs.

  perfidious: While not having read Wolff's book, it was not so many years before when he was one of those young talents getting all the attention. Then, along came droves of strong ex-Soviet players to fight for all the crumbs at random Swisses. Made life tougher for even players at my level (then 2250-low 2300s US), much less those who could reasonably expect to contend with the 2500-plus opposition over the course of these events.

  al wazir: I got white's first five moves (hooray!), but hadn't looked as far ahead as black's next, 32...Nc8. My response was (would have been) 33. Bb5. After 33...Nb6 34. Ba6 Ke7 35. Nxc8+ Nxc8 36. Rxc8, it looks like a draw.

I don't see why black played 33...f5. After 33...Rc1+, where's the win?

  patzer2: Even though I'd analyzed (28. ?) with a computer nearly 10 years ago, I completely forgot about it and missed today's 28. Nd4! Saturday solution. My weaker try 28. c7 gives White a small edge after 28. c7 Rc8 29. Nd8!

The only consolation is that now that I've gone over it again with Deep Fritz 15, the game continuation 28. Nd4! is much easier for me to visualize.

The losing move appears to be 27...Ne7?, allowing 28. Nd4! (+2.00 @ 28 depth, Komodo 9.3).

Instead, 27...Nc7 = (-0.11 @ 21 depth, Komodo 9.3) seems to hold.

  morfishine: <28.Nd4> seems the most natural but I would just respond 28...Ng6 eyeing <f4>
Feb-13-16  diagonalley: beyond me :-(

  morfishine: After going over the game, Black could've played 27...Nf4 instead of 27...Ne7 followed by my idea 28...Ng6 then 29...Nf4. Not that getting there earlier holds, but it looks better probably costing Black an exchange but not a whole piece

  whiteshark: You have to realize that after <28. Nd4 exd4 29. Bxb8 Rxb8 30. c7 Rc8 31. Nd6 Rxc7 32. Rb8+ Nc8 33. Nxc8> even though material is even, black is simply lost.

Way beyond me... ;(

Feb-13-16  luftforlife: <al wazir>: "mill" is short for "windmill." This tactical theme can also feature alternating discovered and regular checks.
Feb-13-16  luftforlife: <al wazir>: Here's a well-known example of the sort I describe from "The Game of the Century" (sc. Fischer's moves eighteen through twenty-two):

Komodo-9.3-64bit:

<+0.00/36 27...Nc7> 28.Rb4 Nc5 29.Nd4 Ra7 30.Kg2 Kg8 31.Nf5 Bf8 32.Bc4+ Kh8 33.Nbd6 Rxb4 34.Nf7+ Kg8 35.N7h6+ Kh8 36.Nf7+

Feb-13-16  Rama: Gee, I saw each move up to Nd6 but did not see where they were leading, because I missed the Rook-check Rb8. :(
Feb-13-16  Patriot: I had two candidates: c7 & Nd4. Nd4 was a candidate immediately because of the x-ray of Bh2-Rb8. I only wish I had ruled out 28.c7 a little faster because of 28...Rc8, but I was focused on black giving the exchange back with 28...Rxb7 as it is more forcing.

28.c7 Rxb7 29.Rxb7 Rc8 30.Rb8 and I suppose 30...Nc5 threatening to go to e6 or d7. But 28.c7 Rc8 may be the easiest and is probably the first thing to consider for black in an attempt to hold on to the exchange while attacking an indefensible pawn.

28.Nd4 Rxb7 29.cxb7 Rb8 30.Ne6+ Kf7 31.Nc7 threatening 32.Na6.

28.Nd4 exd4 29.Bxb8 Rxb8 30.c7 Rc8 31.Nd6 Rxc7 32.Rb8+ Nc8 33.Nxc8 looks very good.

28.Nd4 Nxc6 29.Nxc6 is pretty simple.

28.Nd4 Rc8 29.Nd6 Rc7 30.Ne6+ . 29...Rxc6 30.Nxc6 Nxc6 doesn't appear worrisome.

  PawnSac: < morfishine: <28.Nd4> seems the most natural but I would just respond 28...Ng6 eyeing <f4> >

28...exd4 seems almost forced to keep the knight out of e6. White has ideas like..

..Ng6 29. Ne6+ Kg8 30. Bc4 Kh8 31. c7 Rc8 32. Nd6

< morfishine: ..Black could've played 27...Nf4 instead of 27...Ne7 ..it looks better probably costing Black an exchange but not a whole piece >

Black could give the exchange with 28. ..exd4 29. Bxb8 Nxc6 30. Bd6+ Ke8 also eliminating the c6 pawn, but although it would hold out much longer i suspect this is still losing. In the big picture we would say black simply returned white's exchange sac 25.Rxd5

Your 27...Nf4 idea looked interesting so i plugged it into Stockfish. 1. d4 Nf6 2. Nf3 g6 3. Bf4 Bg7 4. e3 O-O 5. h3 c5 6. c3 cxd4 7. exd4 d6 8. Be2 Qb6 9. Qb3 Qxb3 10. axb3 Nc6 11. O-O e5 12. dxe5 Nd5 13. Bh2 dxe5 14. Rd1 Nb6 15. Nbd2 Be6 16. b4 f6 17. Ne4 Bd5 18. Nd6 Ne7 19. c4 Rfd8 20. c5 a6 21. Ra5 Kf8 22. g4 g5 23. b5 axb5 24. Rxb5 Na4 25. Rxd5 Nxd5 26. Nxb7 Rdb8 27. c6 < Nf4 > 28. Bxf4 gxf4 29. Bc4 Rc8 30. Bd5 Rc7 31. Nh4 Ke8 32. Nd6+ Kd8 33. Nhf5 Bf8 34. Ne4 Rca7 35. Nxf6 Nc5 36. Kg2 Rc8 37. h4 Nd3 38. Be4 Nc5 39. Bf3 Rf7 40. Ne4 Rxf5 41. gxf5 Nxe4 42. Bxe4 Bd6 43. f6 Ke8 44. Bd5 Rb8

This ending is winning for white after Rxb8 and advance the K up to f5

  agb2002: White has a bishop and a pawn for a rook.

Black threatens 28... Nxc6.

White has several options 28.c7, 28.Nd4 and 28.Bxe5 but couldn't find anything decisive.

For example, 28.c7 Rc8 (28... Re8 29.Nd6 recovers the exchange with an extra pawn and much better position) 29.Bxe5 fxe5 (else drop a pawn and Bd6 starts tying Black down) 30.Nxg5 Ra6 (30... Rxc7 31.Ne6+ and 32.Nxc7 wins two pawns, 30... Bh6 31.Ne6+ Kf7 (else 32.Nd6) 32.Bc4 looks ugly for Black).

Or 28.Nd4 exd4 29.Bxb8 Rxb8 30.c7 Rc8 31.Nd6 Rxc7 32.Rb8+ Nc8 33.Nxc8 Kf7 (33... Nxb2 34.Nd6+ Ke7 35.Nf5+ and 36.Rxb2).

I don't know. I think I'd play 28.c7.

Feb-13-16  scholes: extremely tough winning line is 10 moves deep. Good comeback by CG.
Feb-13-16  Patriot: <Jimfromprovidence> You always seem to find a wrinkle. That's one thing I enjoy about your analysis.

It is hard to find anything winning here with only a slight edge to white materially (he has the bishop pair). I would start with 30.Bd6+ which "could" be gaining time to do something else. :-) One could look for setting up a tactical seed via 31.Bf3, using the old x-ray potential threat at some point.

But for REALLY good chess, this would be a great challenge for deciding 28.Nd4 vs. the direct 28.c7 because it requires precision in both calculation and evaluation. Usually I would say a move like 29...Nxc6 is not really much of a challenge because black has lost the exchange, but here he only gives it back! This is a nice example of why we should take an inventory in material before analyzing anything.

Great job!

  morfishine: <Pawnsac> Thanks for looking, thats very good with the analysis. I figured White was winning but thought Black could offer a little more resistance, notwithstanding outside influences :)

*****

Feb-13-16  vajeer: <Jimfromprovidence:> I think 30. Bf3 should do it as White will eventually capture the d4 pawn. In the actual game, Black would only lose d4 pawn instead of the knight by playing 33....Nc5 instead of f5.

  transpose: A beautiful puzzle, and kudos to Kamsky for finding it during the game. I did not get it, looking for something more forcing.
