Nov-04-05  LIFE Master AJ: To explain ...

Leko - Topalov; (San Luis, ARG, 2005) will be my "Game of The Month" for November, 2005. (My "Game of The Month" website is at http://www.geocities.com/TheGOTMman....)

Every month, (in my column) I try to annotate at least one (extra) game. Its part of the "games considered file" that is offered EVERY month now!!!

This game - will be part of the download for November, 2005.

If you would like to see what this looks like, you should go to the October Game of The Month, and download the file for that month. (You must have a ChessBase product to be able to read this file. The free CB Lite may also work, but I have received conflicting reports about the veracity of this. To be sure get Fritz 8 or 9. Not only is it a fantastic program, I have hundreds of downloads on my various websites that are free that you can look at.)

Nov-11-05  Hesam7: <Resignation Trap: It does look natural! The late Lembit Oll tried 14...Bc5 against Kari Pulkkinen at an open tournament in Helsinki in 1990. It went: 15.Rd2 Qc7 16.gxf6 Nxf6 17.Bc4 Be7 18.Bb3 0-0 19.Re1 Kh8 20.Qe3 Bd8 21.Qd4 Bxf5 22.Re5 Bg6 23.Nd5 Qd6 24.f4 Rc8 25.f5 Bh5 26.Rg2 Bf3 27.Rg3 Bxd5 28.Bxd5 Bb6 0-1>

Nov-12-05  LIFE Master AJ: After 14...Bc5; (in the above line); there are something like 5-10 games in the whole of the database. As far as I can tell, NONE of these are a "GM-vs.GM" matchup. So it looks like more testing is definitely needed.

  chancho: <AJ> How do you to overcome The point difference, when you play higher rated players?
Nov-13-05  Hesam7: <LIFE Master AJ: <Hesam7> Pulkkinen was rated 2285, while Oll was 2570. A bit of a mismatch, don't you think?>

Thank you for the information, before using my engine some days after the game was played I thought 14... Bc5 was a better choice for balck. As I have posted my engine supports this idea. Do you have any suggestions for black's 14th move?

Nov-13-05  LIFE Master AJ: <Hesam7>
My engines also indicate that 14...Bc5; is BOTH playable and interesting! Although I did not save all of my work, I went some 20 moves deep at one point. [Unclear?] I would say - as a hunch - that no GM has yet played this move because they felt that their Bishop was needed on the Kingside in order to guard the dark squares. (OR ... maybe no GM has yet seriously considered the play, 14...Bc5!? for Black?)

I would say it is obvious - since there are only a handful of games in this line, and NO "GM-vs.-GM" contests in the database - that more testing is needed! (We can only hope that some prominent GM will play this line against Judit ... and then we can make some conclusions about the real worth of these lines.)

I hate to sound vague, but this is just all a fancy way of saying, "I'm not really sure." Sorry I can't be more precise. But I hesitate to jump to a premature conclusion. Maybe when we have 20 to 30 master-level games with 14...Bc5; (and a few GM's have played the Black side) ... we will be able to make a more precise determination about the worth of 14...Bc5.

  KingG: <LMAJ> Have you finished your analysis of this game yet?
Nov-20-05

  KingG: Strange, a load of posts seem to have disappeared from this page.

Anyway, the Great Goldsby's analysis is finally up on his website(in the form of a downloadable file).

So these are the fruits of AJ's analysis: after 20...Qxe8, AJ analyses the position to a completely winning position for White(it took me about 30 minutes to reach the same conclusion), with Fritz giving 6.43, which bizarrely AJ evaluates as . But after 20...Kxe8(the inferior move according to AJ), he analyses it to a position where White has ♖+♗+5pawns vs Black's 2♖+3pawns. AJ says that he considers this a matter of technique to win this position.(Fritz gives 0.57).

Well, given the choice between two positions, one where Fritz gives +6, and the other where it gives +0.6, i know which one i would rather have.

Note AJ's earlier post where he calls 20...Kxe8 'vastly inferior', and 'after 21.Nd5 White is winning very easily'.

The analysis i(not to mention many other much greater players than me) have done of Polgar's 20.Bb5!!, shows that it is completely winning, so i find AJ's assertion that his move is better than Polgar's slightly bizarre to say the least.

  KingG: Following on from the above post, it turns out that even in even the line that AJ gave that leads to an endgame advantage for White can in fact be improved on.

The line AJ gives in his analysis is: 20.Rxe8+ Kxe8 21.Nd5 Qc5 22.Rxg7 Bxf5 23.Rg3 Rd8 24.c4 Be6 25.b4 Qd6 26.Qc3 Rf8 27.Bg2 Bxd5 28.Bxd5 Rd7 29.Re3+ Kd8 30.Bxb7, which Fritz evaluates as , but Golsby seems to think is . Anyway, i think Black can do better than 24...Be6?!, with 24...Kd7! 25.Bg2 Kc8. The idea is simply to evacuate the King to the Queenside where it will be safer, and then Black has a decent game.

I'll give a few diagrams to illustrate the possible outcomes.

  KingG: Either of the two lines seem preferable to a completely lost game(which you would get after AJ's 20...Qxe8), but AJ seems to think that that they are both inferior. If anyone can explain this to me, i would be very grateful.
Dec-25-05  LIFE Master AJ: This game - and its analysis - continues to generate e-mail.
Jan-19-06  THE pawn: <KingG> You're right, he's wrong.
Mar-16-06  MorphyMatt: The engame looks like Karpov vs Kasparov, 1984
Apr-08-07  jmrulez2004: you know what..it doesnt care whose right or wrong..its about being able to play like those geniuses out there:)
May-17-07  aazqua: THis is absurd. If you aren't going to keep the knight, you can't play this line as black. You give up way to much initiative not to have a material edge.
May-17-07  aazqua: Judit's looking awfully pudgy in this picture. Was she pregnant or something? It's a bad day when you play second fiddle to Kasmin in the looks department.

  Knight13: <22...Bxb2+?? turned what could have been (nearly) a won game, into a lost one.> How? It seems forced to me.
Oct-19-10  Hesam7: <Hesam7: <Resignation Trap: It does look natural! The late Lembit Oll tried 14...Bc5 against Kari Pulkkinen at an open tournament in Helsinki in 1990.

I posted that about 5 years ago and since now I have a powerful new machine, I decided to take another look at the position after 14. ... Bc5:

Stockfish gives the following @ depth 28: (0.00) 15. Rd2 Qc7 16. gxf6 Nxf6 17. Nd5 Nxd5 18. Rxd5 Be7 19. f6 Bd6 20. Bh3 Be6 21. Bxe6 fxe6 22. Qh5+ Kf8 23. Qh6+ Ke8.

I find this quite remarkable. The fact that my machine can see White's compensation just shows the rapid pace of progress in computer science in the past 5 years. The extra 10 ply is a result of a better hardware: Fruit's 600K nodes/sec was achieved on an IBM G5 while Stockfish had a speed of 3000K nodes/sec on an Intel Core i5. On the software side Stockfish is a much better engine than Fruit hence even on the same hardware it would give a higher quality analysis.
