|Apr-21-06|| ||goldenbear: h3 has a 100% win ratio for white, according to our database, an impressive 2-0, including a correspondence chess victory in 1991.|
|Apr-21-06|| ||Mendrys: Knowing this was a puzzle position I got all the way to 20. Rf1+ but was unsure how to press the attack. So....I did not solve this puzzle. Like <Kevin86> I did not see the penetration of black's eighth rank. Even so I still have doubts about the soundness of the sac. <United33>, <Life Master AJ> can be a bit of a troll if you disagree with him. The fact the he has to clear one of his 40 allocated slots on the ignore list for you says quite a lot.|
|Apr-21-06|| ||EmperorAtahualpa: Nice puzzle, even though Black "blundered", but that doesn't really matter. "Blundering" is a way too negative word in sharp positions like these, in which one move can make a tremendous difference.|
20...Kg6 really isn't such a bad move, it's much more realistic to honor White with his brilliant response to it!
I was looking at 18.Rxf7+ Rxf7 19.Bxf7 Kxf7 20.Rf1+, but couldn't find any follow-up! Like some others, I was also looking at 18.d4 and 18.h4
|Apr-21-06|| ||goldenbear: <Mendrys> Man, give <Life Master AJ> a break. Anyone who contributes to this site as much and as meaningfully as he has deserves some respect. Also, people who breathe chess tend to be a touch eccentric. Furthermore, his ignore list shows only that he is weary of personal attacks; I might do the same if I were him. I, too, can be a bit sensitive at times. If you don't think 40 users have attacked him personally (not having anything to do with chess), read around.|
|Apr-21-06|| ||Jim Bartle: I respect AJ on purely chess issues, and yes he contributes, but I can't resist giving him a hard time on non-chess matters.|
|Apr-21-06|| ||melianis: I saw 18.h4, do i get 1/8? No, serioulsly did not think such a straightforward assault was possible. Credits to the executor.|
|Apr-21-06|| ||goldenbear: <Jim Bartle> Fair enough. It depends on taste and intention, I guess.|
|Apr-21-06|| ||Mendrys: <goldenbear> Don't get me wrong, I respect <Life Master AJ> for his depth of chess knowledge and many of his inciteful posts. I was only trying to be slightly critical. I agree he has his detractors and many of them have indeed made personal attacks. Perhaps <bit of a troll> was too harsh, but he can be awfully sensitive to mild criticisms or when someone disagree's with him.|
|Apr-21-06|| ||Paintbucket: Bingo. I got that one. First thing I saw too.|
|Apr-21-06|| ||HELLOHELLOWATER: can anyone read my message??|
|Apr-21-06|| ||blingice: Holy crap, <HHW>, you've asked this question for several different pages, and they've all been yes. Why should the website react differently today?|
|Apr-21-06|| ||Halldor: <Apr-07-06 HELLOHELLOWATER: just checking if my kibits actaully works, so if you can read this message, type I CAN READ IT> |
I CAN READ IT! - I CAN READ IT!! - I CAN READ IT!!!
|Apr-21-06|| ||jmelton: As several people have pointed out, the combination played in the game, the supposed solution to the puzzle, can be successfully parried by Black. So, for example, 18. Rxf7+ Rxf7 19. Bxf7 Kxf7 20. Rf1+ Ke8 21. Qf2 Nc6 22. Qf7+ Kd8 23. Rf6 Qe7 24. Qg6 Bd7 25. Qxh6 Kc7 26. Qg5+ Re8, and Fritz rates the position about even. I didn't really need Fritz to tell me that in all likelihood 20...Kg6 was not the greatest defense by Black.|
But something told me White's position was too good for there not to be anything better than the line above. It looked to me like the best plan had to involve pinning the e-pawn with Qc3 and building up the pressure on the f-file by doubling rooks. So I ran some possibilities through Fritz (4.01, an oldie but as far as I can tell not sigificantly weaker than more recent Fritzes). It came up with the following killer line that was based on that plan:
18. h4 g4 19. Rf2 f6 20. Rdf1 b5 21. Qc3 b4 22. Bxe5!! fxe5 23. Qc4 Rxf2 24. Rxf2, and with his Rook and Bishop out of play, all Black can do to stop the enemy piece invasion is give the piece back with Nd5. Black winds up a pawn down with no compensation.
20...Be6 fails to 21. Rxf6! Rxf6 22. Rxf6 Kxf6 23. Qxh6+ Kf7 24. Qh5+ Ng6 25. Qh7+ followed by h5.
The other reply to 18. h4 g4 19. Rf2 that I had Fritz look at was 19...f5. Here's what came up: 20. Qc3 Nc6 21. Re1 Qd4 22. Qxd4 cxd4 23. exf5 Rxf5 24. Rxf5 Bxf5 25. Bxe5 and, again, White is a pawn up with no compensation for Black.
So, it appears that Adrian was correct to judge the position as containing exploitable Black kingside weaknesses, but the sacrifice he played appears to be premature and not the correct way for White to take advantage of Black's weaknesses.

|Apr-21-06|| ||hopeful monster: A few kibitzers, including me, thought the best move was 18. h4. Interestingly, both Rybka and Fruit agree that h4 is the best move (+1.0) and that 18. Rxf7+ lets White's advantage slip.|
|Apr-22-06|| ||LIFE Master AJ: Hoping to put any controversy to rest ...
<goldenbear> got it right ... I am very, very, very weary of personal attacks. (I have been criticized here for religion, politics, shoe color, you name it. And I certainly will not respond to threats, insults, harassment, etc. When someone intentionally messes up my handle, - an an attempt to cause ridicule - then demands information from me; it makes me wonder if such an individual is a few rocks shy of a truckload.)
Trying out the "pure" version of Fritz 9, (under the ChessBase interface); apparently Fritz already considers this a COMPLTELY WON POSITION (just before the sack on f7) FOR WHITE. ("plus-slash-minus") Secondly it likes (AGGRESSIVE) moves like h4, intsead of the sack on f7.
Thirdly, when analyzing these type of problems, I use a MODIFIED version of Fritz ... especially set to be hyper-agressive. (sac's) Modifying an engine under the ChessBase interface is very simple, simply right-click on the engine part of the window and select properties. You can modify dozens of attributes, and if you wish to go under the program itself, you can make many more modifications to any aspect of the engine that you like. (Just don't save it under the main engine file, otherwise you have to do like I did and re-install the program to get the "standard" settings back.) When analyzing with this aggressive engine, taking on f7 was the second choice of the program, h4 was the first, (I believe).
Fourth point - ...Kg6 may have been an error, and I was NOT the first to point this out.
Fifth, I don't have this game on the CD-ROM version of the informant, but I have many Informants for that period. (# 63-71 or 72) As soon as I finish up a few other projects, I may copy parts of that analysis here, as to shed some light onto how the players viewed this game.
As Ermenkov - Kovacevic already amply proved, even GM's can miss key moves at crucial points in the game.
Finally, when my tax return comes back, I will probably check out Rybka, depending on how much it costs.
|Apr-26-06|| ||patzer2: <LIFE Master AJ> <I would classify this as a denuding sacrifice, would anyone else agree. <patzer2>> I'd agree that it's a denuding or "demolition sacrifice" intended to weaken the King position.|
I'm including it in my "demolition of pawn structure" collection, even though it appears to be a genuine sacrfice with an uncertain outcome. However, it is certainly a pratical OTB try, as it offers White winning chances with apparently no worse than equality with strong play.
After 20...Ke8! 21. Qf2! Nc6! 23. Qg7 Bd7 24. Rf6 Qe7 25. Qh8+ Be8 26. Rxh6 Rc8 27. Rh7 Qe6 28. Rxb7 Rc7 29. Rxc7 Kxc7 30. Qg7+ Kd6 31. Qxg5 = (0.00 @ 16 depth per Fritz 8) White appears to have equality in a complex and unbalanced position.
|Apr-28-06|| ||LIFE Master AJ: < <patzer2> "However, it is certainly a pratical OTB try, as it offers White winning chances with apparently no worse than equality with strong play." > |
I would have to say that this is a pretty accurate assessment.
|May-04-06|| ||LIFE Master AJ: Hopefully, in the next month, I will have a chance to analyze this game.|
|Jan-13-09|| ||WhiteRook48: Queen on h8 is interesting...|
|Jan-27-09|| ||WhiteRook48: well, it was pretty hopeless with a Q on h8 and an R on f8...|
|Jan-28-09|| ||WhiteRook48: 23...Ra7 does not seem relatively best|
|Jan-30-09|| ||WhiteRook48: "Never move the h-pawn until the end of the game"|
|Mar-05-11|| ||perfidious: Without doing a great deal of concrete analysis as I look at the monitor, it seems to me that 20....Kg6 can't be right, and I'm more than slightly curious why a strong GM such as Sturua rejected the alternative 20....Ke8.|
As to whose computer is better, we're looking at vintage <Life Baiter AJ> in motion, with threats and vituperation aplenty.
Maybe I'll next be favoured with the threat of getting on his wonderful ignore-list.
