Nov-12-05		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.

Nov-17-05		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.

Nov-20-05		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. This is the outcome of the line i give click for larger view This is the outcome of AJ's line click for larger view

Nov-20-05		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.

Jun-03-08		arsen387: I understood completely nothing from middlegame, but the endgame was nice :)

Aug-06-09		Winter: All's Well That Ends Well...

Aug-20-09		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. 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> I ran Fruit after 14. Rxd4. Here is the result: 14... Bc5 15. Rd2 Qc7 16. gxf6 Nxf6 17. Nd5 Nxd5 18. Rxd5 Rg8 19. Qe4 Be7 20. f6 Be6 21. fxe7 Bxd5 22. Qxd5 Qxe7 23. Bc4 Rd8 24. Qf3 b5 25. Bd3 Qe6 26. Bxh7 (eval: -0.47) Depth: 18 5147M nodes 683K nodes/sec> 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: click for larger view 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.

Aug-20-11		ahmadov: The lady rules...

Aug-20-11		ahmadov: This is one of my best Guess the move games... (87 points when the par was 59 points...)

Nov-01-17		posoo: Now DIS game is a FROD. so is da PUTTUNI GAMVOT. Even CHESSE is not meant to have DIS much smashing. Chill out everyone!

Apr-12-18		HeMateMe: Judge Judy!

Sep-24-20		mahaprabhu krishna: Her Home prep with tactics recognising ability is super amazing.

Oct-30-20		Messiah: What a terrible pun! Truly horrific!

Mar-11-25		plang: 7 g4 is the super sharp Perenyi Attack which Polgar had previously used against Anand at Dos Hermanas 1999 which was one of the most brilliant wins in her career (her career score in this variation had been 2/2 with White and 3.5/5 with Black). Against Anand Polgar had played 13 Bd2; here she had prepared the rarely used 13 Bxd4 which Kashimdzhanov could not have been expecting. Polgar after 14 Rxd4: "Hurrying to take on f6 makes no sense, since it would ensure Black some space and stability." 14..Bc5 had been played by Oll in a 1990 Finnish tournament; 14..Bg7?! was new but later analysis showed that it makes it difficult for Black to defend. 17..h6?! spent a tempo to clarify matters but 17..Rg8 would have been a better defense. 21..b4? should have lost immediately but Polgar missed the relatively straightforward 22 Rxe8+..Kxe8 23 Rxe7+..Kxe7 24 Nd5+..Kf8 25 Nb6..Bf6 26 Nxa8 with a winning material advantage. Instead, Polgar's 22 Nb5? gave Kasimdzhanov the opportunity (which he missed) to turn the tables with 22..Be5! when 23 f4 is no longer effective due to 23..Rxa2!. After the offsetting blunders White regained control and coasted to victory. Certainly, a great fighting game despite the late game errors.

Mar-12-25		HeMateMe: It's always fun to look at the old comments/analysis. AJ is still around, I believe, pops in every now and then, 20 years later.
