Oct-04-05  VishyFan: <Hesam7> which version of Fruit are u using?
Oct-04-05  Hesam7: <VishyFan> The free one (Fruit 2.1). But I am running it on a very fast computer.
Oct-04-05  VishyFan: <Hesam7> how fast?
Oct-04-05  Hesam7: <VishyFan> I am using a Power Mac (dual G5 2.5 GHz processors, but Fruit gets executed on one of them). The minimum speed is 600K nodes/sec, in more simplified positions it can reach 1M nodes/sec or more.
Oct-05-05  Boomie: <Hesam7> Yes, I use Fritz 8. After 20...♕b4, Herr Fritz prefers ♕b1 over ♖a2, ♘g4, or ♕c1. Admittedly all these moves look lame. This is in part due to the power of the black queen on b4. I wonder why Anand played ♘c4 instead.
Oct-07-05  blingice: I love how full the stands are.
Oct-11-05  Hesam7: <Boomie> thx for the response. I think 20... Nc4 was Anand's main mistake. IMO there is no return point for Black after that, white's victory is a matter of technique. Here is analysis of the position after 22. Qg4 by Fruit 2.1:

22... Qb4 23. Qxe6 Qxb2 24. Rab1 Qxc2 25. Rxb7 Rf6 26. Qe3 Qd2 27. Rc1 Qxe3 28. fxe3 Na5 29. Ra7 Re6 30. Bc7 Nc6 31. Bxd8 Nxa7 32. Rxc4 Rxe3 (eval: +0.94)

Depth: 19
8961M nodes
722K nodes/sec

Oct-15-05  THE pawn: <Hesam> I think you've given a site to someone a few days ago,in which you can download fruit. My engine don't want to open and I can't find the problem, so I would use fruit as a replacement. Do you have an adress where I can download it?

  patzer2: This is an extremely difficult game to analyze. Even the GM analyts who I've seen comment on it seem to me to be a bit uncertain as to exactly where Anand lost it.

Some have suggested <30...Nh4!?> may be the culprit. For example GM Shipov has suggested at that <after 30...b5! Black still has chances to save a game.>

However, <Hesam7>'s analysis to 20 depth with Fruit 2.1 indicates White obtains a clear advantage after 30...b5! 31. c3 with good winning chances for White, suggesting White may be facing a forced loss.

Although I'm far from certain, I think my Fritz 8 program may have improved on Fruit's analysis to find a forced win. <Hesam 7> gives Fruit's first ten moves of analysis at 20 depth as <31. c3 Qd6 32. Rxd2 Qxd2 33. Bd5 Qf4 34. Qe8 Rf8 35. Qd7 Kh8 36. Qe6 g4 37. hxg4 Nd6 38. Re2 Qc1 39. Kh2 Qf4 40. g3 Qf6 41. Qd7 .>

I used Fritz 8 to verify these first ten moves, but then found Fritz 8 offered a different recommendation, offering up 41. Qe3! instead of 41. Qd7. The analysis using Fritz 8 continues 41. Qe3! Ne8 42. Bb7 Nc7 43. Qb6 Qg7 44. Rd2 Re8 45. Bxa6 Nxa6 46. Qxa6 Qxg4 47. Qxh6+ Kg8 48. Rf2 Qg7 49. Qc6 (+ 2.84 @ 16 depth & 1339kN/s).

Yet even though 31...b5! might give White a win with perfect play, with Kasimdzhanov in time trouble, Anand would IMO have excellent chances of holding for a draw with this move. Why? Becase 31...b5! offers practical counter chances as the winning moves for White require deep calculation unlikely to be found in a time scramble.

  patzer2: IMO <Hesam 7> and GM Shipman are spot on in indicating <20...Nc4> was the positional mistake that sowed the seeds of defeat for Anand in this game. In GM Shipov's words, <20...Nc4> was the <beginning of Black’s suicidal activity.>

Instead, both Fritz 8 and GM Shipov at recommend 20...Nd7! as giving Black even or better counter-attacking chances.

BTW, Fritz 8's evaluation of the 30...b5 31. c3! line given in the above post is now +3.12 @ 19 depth.

  patzer2: The clear winning combination for Kasimdzhanov was 33. Bh5!!, launching a decisive attack on Anand's weakened castled position.
Premium Chessgames Member
  patzer2: Here's a break out of the winning 33. Bh5!! using Fritz 8:

<33. Bh5 Ng6>
No help for black is 33... Rxd1
34. Rxd1 Qf8 35. Rd7+ Kg8 36. Qd5+ Kh8 37. Rd8 Rf1+ 38. Kh2 .

<34. Bxg6! Rxd1>
The capturing Bishop is poison as
34... Kxg6 35. Qe8+ Rf7 36. Qg8+ Kf6 37. Rf1+ Ke5 38. Qxf7 wins for White.

<35. Rxd1 Kxg6 36. Qe4+ Kg7 37. Rd7+ Kg8> White wins after 37... Rf7 38. Qe5+ Kg8 39. Rd8+ (not 39. Qe8+? Qf8 ) 39...Rf8 40. Qe6+ Kg7 (40... Kh8 41. Qxh6+ Kg8 42. Qe6+ Kh8 43. Qe5+ Kg8 44. Rd7 Rf7 45. Qxg5+ Kf8 46. Rd8#) 41. Rd7+ Kh8 42. Qxh6+ Kg8 43. Qh7#.

<38. Qh7+ 1-0>
What follows is the obvious 38...Kf8 Qh8#.

Nov-09-05  Hesam7: <patzer2> Cool analysis! Beside the engine analysis, Black is also lost after 20... Nc4 if you consider general factors. This is one of my earlier posts:

<Hesam7: IMO 20 ... Nc4 was Anand's main mistake, after 21 Nxc4 dxc4 22 Qg4 Anand's position is no more defendable. The light squares around Black king are weak, the e6 pawn is another weakness also add the bishop pair in an open position. The game is strategically lost from that point.>

Premium Chessgames Member
  patzer2: <Hesam7> I suspect you're right about 20...Nc4?! losing for Black. The analysis is difficult, but in most lines White ends up with an extra pawn, strong Bishop versus Knight, safer King position, and with the initiative and more space. If not a recipe for a forced loss for Black, it certainly has all the necessary ingredients.

Certainly, 20...Nd7! with good counterplay is preferable to being slowly tortured in an inferior position after 20...Nc4?!

Nov-09-05  blingice: Oh, Nd6+
Feb-05-06  foxbat: No, not 27 ... Nd6+?, 27 ... Qc5+! and white is toast. CI94 Game 179.
Jun-16-09  tivrfoa: few people in the bleachers
Jun-16-09  Udit Narayan: <tivrfoa> Chess has rapidly gained popularity in the past few years ;)

Jun-17-09  tivrfoa: <Udit Narayan> wow. many girls. I need to become a grandmaster too!!! xD

Apr-07-14  vsiva1: what about 37. ...Rf7 ?
Feb-09-15  Volmac: <vsiva1: what about 37. ...Rf7 ?> On 37...Rf7 follows 38.Qe5+ Kg8 (38...Kg6 39.Qe6+ Rf6 40.Qe8+ Kf5 41.Rf5+ Kf4 42.Qe5 mate) 39.Rd8+ Rf8 40.Qe6+ Kh8 41.Qxh6+ Kg8 42.Qe6+ Kh8 43.Qe5+ Kg8 44.Rd7 with mate to follow, for example 44...Rf7 45.Qxg5+ Kh8 46.Qh5
