  patzer2: <Hesam7> Thanks for the reply. Yes I am looking back into the San Luis games. My work sometimes takes me away from the computer for a week or so, and I'm playing catchup. Also, I find it is good to let the smoke clear for at least a few days on these super GM tournament games and to take my time on the analysis. Afterall, the super GMs sometimes spend months and years finding these lines. By allowing a little time for GMs to post their analysis and taking my time with my own computer assisted analysis, I can better understand their subtleties.

In this case, I strongly suspect you are correct that GM Shipov was mistaken in his assessment of <23. Qd2!!> as a forced win, but the position is so complex I wouldn't be surprised if Anand or another analyst came up with an improvement on the computer analysis. If Anand plays into it again, that might be a clue. However, for now it looks to be that <23. Qd2!?> offers winning chances only if Black misses the best defense, but otherwise (with Black's best play) only seems to lead to a draw by perpetual check.

Premium Chessgames Member
  patzer2: Does anyone know of any GM analysts who've looked at Hesam 7's and Fruit's defense of 23. Qd2!?, allowing Black to force a draw and contradicting several GM analysts claiming it is a forced win for White.

I found where Goran Urosevic at endorses the idea that the line given by Hesam 7 and Fruit most likely leads to a forced draw.

However, so far GM Shipov (see link above), William Pien at and apparently Zsusza Polgar (according to JMelton's post above) appear to have endorsed the idea that 23. Qd2!? is a forced win for White.

Perhaps some of our GM, IM or Master kibitzers on this site would like to weigh in with an opinion?

I ran the line in question, 23. Qd2!? Nxe1 24. Nxe1 Ra1 25. Nxh6+ Bxh6 26. Qxh6 to 18 depth & 1171 kN/s on Fritz 8 and a 2 GHZ AMD processor with the following results:

Anand,V - Adams,M

(26...? Black to move)

Analysis by Fritz 8:

1. = (0.00): 26...Nxd5 27.e5 Rxb1 28.Rxg6+ fxg6 29.Qxg6+ Kf8 30.Qf5+ Kg7 31.Qg5+ Kf7 32.Qf5+ Kg8 33.Qg6+

2. = (0.00): 26...Re5 27.Nf3 Rxb1 28.Rxg6+ fxg6 29.Qxg6+ Kf8 30.Qh6+ Ke8 31.Nxe5 Rxc1+ 32.Kh2 Qxf2 33.Qe6+ Kf8

3. (0.62): 26...Re7 27.Be3 Qd8 28.Bd4 Re5 29.Bxe5 dxe5 30.Qc1 Na2 31.Qd1 Nb4 32.Ra3 Rxa3 33.bxa3 Na6 34.Bc2 Qd6

4. (0.69): 26...Qd4

Nov-16-05  Goran: I really believe Adams had resources to pull the draw. He was probably too shocked with Qd2
Dec-14-05  AdrianP: "[Kasparov] reveals that he already discovered Anand's spectacular novelty [viz 23 Qd2!?, I guess] Nagainst Adams in San Luis back in 1989." (New in Chess)
Dec-14-05  alicefujimori: <AdrianP>That is no suprise since Kasparov has analyzed that position for so long during his preparations for his matches against Karpov.

  TheAlchemist: After a brief analysis with my CM10 I found some another beautiful line, that also seems drawish, however:

23...Nxe1 24.Nxh6+!? Bxh6 25.Qxh6 Nxf3+ 26.gxf3 Re7

(Or perhaps 26...Re5 27.f4 Ra1 28.f5! Rxf5 29.exf5 Rxb1 30.fxg6 Rxc1+ 31.Qxc1 with an, I would say, unclear position)

27.Be3 Qd8 (the only move, after 27...Qc7 28.Bg5 or 27...Qa5 28.Rg4) 28.Bd4 Re5 (the only move) 29.f4 Ra1 30.fxe5 Rxb1 31.Kh2 Qf8 (the only move) 32.Rxg6+ with perpetual check

I don't know if everyhing here is correct. <Hesam7> What does Fruit have to say about the position after 26.gxf3?

Dec-14-05  Hesam7: <TheAlchemist> After:

23... Nxe1 24. Nxh6+? Bxh6 25. Qxh6 Nxf3+ 26. gxf3 27. Be3 Qd8 28. Bd4 Re5 29. f4 Qf8!

Fruit gives:

30. Qxf8 Kxf8 31. fxe5 Ra1 32. exd6 Rxb1 33. Kh2 Ke8 34. h4 Rd1 35. Bc3 Nd3 36. h5 gxh5 37. Rg7 Nc5 38. d7 Kxd7 39. Rxf7 Kd6 40. Rf6 Kc7 41. Be5 Kd8 42. Rf8 Ke7 43. Rh8 Nxe4 44. Rh7 Ke8 45. Rxb7 Rxd5 (eval: -1.50)

  notyetagm: This game just won the Chess Informant Best Game Prize, yet another one for Anand.

Anyone know how many Informant Best Game Prizes Anand has now won?

Premium Chessgames Member
  Jim Bartle: Through Informant 64 (up to 1995) his only #1 game was against Ftacnik at Biel 1993. Two losses to Kasparov in 1995 were also rated as the best games.
Apr-24-06  you vs yourself: <notyetagm> How many best game prizes do they give out each year? Didn't you say Topalov won one for his win over Anand?
Premium Chessgames Member
  Jim Bartle: They rank one game as the best from each issue of Informant, and there are three per year now.
Apr-24-06  you vs yourself: <Jim Bartle> Thanks!

  notyetagm: <Jim Bartle: They rank one game as the best from each issue of Informant, and there are three per year now.>

Yes, Topalov won the previous one for his win over Anand at M-Tel 2005. Anand just won the most recent one for this victory over Adams at San Luis 2005.

And the next Best Game Prize award is going to be a fierce battle between Anand's ... ♘c7!! victory over Karjakin and Topalov's double exchange sac on e4 win over Aronian, both from Corus 2006.

Aug-08-06  positionalgenius: Adams only defense to this kasparov-grade attack was 23...Nxe1.Still he would have only a draw at best.Great Anand game...
Aug-18-06  dravid: One of Anand's finest!
Feb-22-07  Brown: 23.Be3 is more natural and probably better.
Apr-22-07  Atking: <TheAlchemist: After a brief analysis with my CM10 I found some another beautiful line, that also seems drawish, however: 23...Nxe1 24.Nxh6+!? BxNh6 25.QxBh6 NxNf3+ 26.gxNf3 Re7!> With the idea of Qd8~Qf8 < (Or perhaps 26...Re5 27.f4 Ra1 28.f5! Rxf5 29.exf5 RxBb1 30.fxg6 RxBc1+ 31.QxRc1 with an, I would say, unclear position)> I will prefer White here. To say 31. ...Nd3 32.gxf+ Kxf7 33.Rf3+ If Ke then Qg5 or Qh6 R+Q will trap the King. Else Kg then Qf1!. White has a clear advantage here too. Therefore 26. ...Re7! looks deepest. But instead of "your" 27.Be3?! (Black Queen want to go to f8. This helps) why not pursuie his way by 27.Bg5 ? 27. ...Qd4 28.BxRe7 Qe5 29.Qh4 Kg7 30.f4 Qxb2 31.Bxd6 QxBb1+ 31.Kh2 Qxe4 32.Be5+ Kf8 33.Re3! 27. ...Nxd5 is probabbly the point but I'm not sure that'enought. 28.exNd5 Re1+ 29.Kh2! Qxf2+ 30.Rg2 Qxf3 31.Bxg6 fxBg6 32.Qxg6+ Kf8 33.Bh6+ Ke7 34.Qh7+ Qf7 35.Rg7 looks good for White. I really like Anand's 23.Qd2!! clearly deeper than the oubvious 23.Be3 Maybe an intuitive move. With Bc1 and Bb1 Black7s counter on queen side is one tempo slowest and the Queen could be stronger than a R+N+B if the King is without pawn to protect him.
Mar-06-08  Udit Narayan: looks like both Adams and Kasimdzahnov are testing their earpieces to see if Fritz is coming loud and clear :)
Dec-26-09  Hesam7: After 19. ... Qb6 20. Nf5:

click for larger view

<1) 20...g6 21 Nf1!. I very much liked this move: 21...gxf5? 22 Rg3+ Kh8 23 Bxh6! or 22...Kh7 23 Qh5 Ne5 24 exf5. But 21...Rxa3 is acceptable: 22 bxa3 Nxd5 23 exd5 Rxe1 24 Qxe1 gxf5 25 Be3 Qd8 (DeFirmian vs A Ivanov, 1996), 25 Bxf5 Ne5 (A Volokitin vs S Azarov, 2007) or 25 Ne3 Qd4 26 Nxf5 Qxd5 27 f3 - it seemed to us that here Black 's defence was difficult, but after 27...Qe5 he holds on;

2) 20...Ne5. This looked extremely dangerous because of 21 Rg3 g6 22 Nf3, although after 22...Ned3 nothing decisive for White is apparent: 23 Be3 (if 23 Qd2, then 23...Nxe1, but not 23...Bxd5? 24 Nxh6+! Anand vs Adams, 2005) 23...Qd8 24 Bxd3 Nxd3 25 Nxh6+ Bxh6 26 Bxh6 Nxe1 (26...Qf6!?) 27 Qxe1 Qf6 or 24 Bxh6 Qf6!; a universal maneuver. Now 25 Bxf8? Kxf8 is unfavorable, but Kotronias's recent attempts 25 Qd2 and especially 25 N3h4!? are interesting.

We analyzed 19...Qb6 20 Nf5 a great deal and considered it promising for White (a part of this analysis is still topical today!), but modern theory and practice do not confirm our optimism.> -- from "Kasparov vs Karpov 1986-1987" by Kasparov when commenting on 19. ... Rxa3!? in Kasparov vs Karpov, 1986.

Oct-19-10  sevenseaman: 25. Qxh6. The Q abandons defence of f2 to go on the offensive but Anand was equal to the half-baked Adams attack deep in his own barracks.
Apr-06-11  Jaideepblue: Anand prepared 23. Qd2 against Kamsky in their 1995 match. It came into use a decade later though!
Dec-04-13  Fabianx: Interestingly both Critter and Stockfish see Black at an advantage here:

Stockfish giving:

0.00 [+] [*] 23... Nxe1 24. Nxe1 Na2 25. Nxh6+ Bxh6 26. Qxh6 Nxc1 27. Rxg6+ fxg6 28. Qxg6+ Kf8 29. Qf6+ Kg8 30. Qg6+ (Tiefe 26, 1:09:36)

while Critter says:

That just after one hour of analysis.

Interestingly is that both engines briefly had the original line played in the game, but considered it positive for Black (+0.55) and did not lead to a mate like in the original game, like:

"23... Bxd5 24. Nxh6+ Bxh6 25. Qxh6 Qxf2+ 26. Kh2 Nxe1 27. Rxg6+ fxg6 28. Qxg6+ Kh8 29. Qf6+ Kg8 30. Qg6+"

The move played by Adams is considered by engines, but later thrown away as better moves arrive.

Just as information for those that are interested in 23. Qd2?!.

Dec-04-13  Fabianx: The most surprising idea, here being:

23... Re7 24. Rf1 Qd8 25. Nxh6+ Bxh6 26. Qxh6 Qf8 27. Qh4 Nxc1 28. Rxc1 Rae8 29. Qf6 Qg7 30. Qxg7+ Kxg7

Even without a computer, this looks do-able for black.

Dec-05-13  Fabianx: And then after:

31. Nd4 Kh6 32. Nxb5

Two nice variants are:

32... Ba6 33. Nxd6 Rd8 34. e5 Nd3 35. Bxd3 cxd3 36. Rd1 f6 37. f4 Rf8 38. b4 fxe5 39. fxe5 Rxe5 40. b5 Rxd5 41. Rdxd3 Rxb5 42. Nxb5 Bxb5 43. Rd6 Be8 44. Re3 Ba4 45. g4 Rf4 46. Kg2 Bc2 47. Kg3 Rb4


32... Ba6 33. Nxd6 Rd8 34. e5 Nd3 35. Bxd3 cxd3 36. Rd1 Rxd6 37. exd6 Re5 38. Rgxd3 Bxd3 39. Rxd3 Re8 40. b4 Rd8 41. f4 Kg7 42. Kf2 Kf8 43. Ke3 Ke8 44. Rc3 Rxd6 45. Kd4 Rf6 46. g3 Rb6 47. Kc5 Rb8 48. b5 Kd7 49. b6 f6 50. h4 f5 51. Rc4 Re8 52. Kb5 Rb8 53. Rc6

both after around 14 hours of calculation with depth 36 / 27.

  offramp: I think the Zaitsev is a fantastic system but it certainly has an organic weakness. One of the points is that black avoids Smyslov's 9...h6; but often he has to play it later anyway to prevent Ng5.

BUT he also tends to play ...g6, often so as to put the bishop on g7. And black's counterplay is often based on ...f7-f5.
There is always a problem that a good player is going to smash that f5-g6-h6 castled position to smithereens.

Petrosian disliked ever moving pawns in front of his king - but this wasn't his type of opening. It is a case of horses for courses.
