|Jan-07-04|| ||Benzol: Looks like Geller saw the implications of 14.♗b6 but overlooked the simple double attack of 14.axb5 |
|Jan-08-04|| ||Reisswolf: What's wrong with 13. ♗b6 ♕a4 14. ♕c1, threatening 15. b3? I haven't looked very closely, but on the face of it, my variation also seems to win. |
|Jan-08-04|| ||crafty: 13. ♗b6 ♕a4 14. ♕c1 bxc4 15. ♗xc4 e6 16. b3 (eval 4.78; depth 15 ply; 500M nodes)|
|Jan-08-04|| ||euripides: Another possibility might be 13 Bb6 Qa4 14 b3 Qa3 15 Ne1 (aiming for c2) Nb4 16 Bc5 a5 17 Nc2 Qb2 18 Nxc5 ab 19 Bd4 and I think the queen is lost. |
|Jan-08-04|| ||euripides: What is Black's mistake here ? Perhaps he should avoid the Q excursus and play 7...Na6. Also 10...a6 gives problems, but by then the queen is aready in danger; 10...Nd4 might be worth considering. Possibly even 5...c5 is dubious - 5...d6 may be better. |
|Jan-08-04|| ||kevin86: 13♗c6 is my choice-but either way-black is as cooked as this problem LOL |
|Jan-08-04|| ||nf3wins: I dont really see anything wrong with 13...pxp. I was looking at 13. Nxe7 Nxe7 Bc5 |
|Jan-08-04|| ||dukesterdog: 13...pxp is followed by 14.Bb6, and Black loses the queen. |
|Jan-08-04|| ||Netheron: I think the lesson here is clear. Don't bring out your queen early in the game, at least without a retreat path. 8..Qxc5 is the real problem. Queens tend to get indigestion on early pawn gobbling. |
|Jan-08-04|| ||patzer2: My selection was 13. Nb6! After 13. Nb6! Rb8 14. Nxd7 Bxd7 15. Qxd7 Nb4, where it appeared to me White had a win (pawn up and ready to win another pawn with better development). Fritz 8 confirmed my analysis by indicating that White now has the option of at least six winning moves (16. Bc5! or or 16. Nd4! or 16. Ba7! or 16. Rd1! or 16. Qxe7 or 16. Bd2).|
Fritz 8's best line here goes 13. Nb6! Rb8 14. Nxd7 Bxd7 15. Qxd7 Nb4 16. Bc5! bxc4 17. Bxe7 Nd5 18. Bxf8 Bxf8 19. Kg3 Ne3 20. Ng5 Qc7 21. e6 (2.09 @ 14 depth & 676kN/s) A second Fritz 8 deep analysis continues 21...Qxd7 22. exd7 Nf6 23. Kf3! Nxf1 24. Rd1! Rd8 (if 24...Be7, 25. Rxf1 -) 25. Rxf1 and White with an exchange and a pawn up plus the initiative has a decisive advantage (+2.53 @ 15 depth & 756kN/s).
|Jan-08-04|| ||AdrianP: I take it that this game Keres vs Geller, 1952
is an erroneous copy of the present game... (or vice versa)|
I share <euripides>' view that 5...c5? is (very) dubious. 5...d6 is a main line.
|Jan-08-04|| ||patzer2: According to Fritz 8 (@13/40 depth & 658kN/s), also winning for White are 13. b4 (+3.13) or 13. cxb5 (+2.50) or 13. Nd2 (+2.72) or 13. a3 (+2.37) or 13. Bc5 (+2.37), in addition to the three other winning moves previously discussed (13. a4, 13. Bb6 and 13. Nb6). Fritz 8 rates 13. a4 (+4.50) as a best move and 13. Bb6 (+3.84) as second best. |
With eight possible winning moves after 12...b5, I suppose it was likely White would find one of them. To his credit, he found the best one.
|Jan-08-04|| ||patzer2: The King's Indian Defense, Four Pawns Attack (5 f4), is the subject of an ongoing theoretical debate. Is the extended pawn center an asset (facilitating attack) or a liability (leaving the extended pawns too vulnerable to a counter-attack)? In this game, Kere's makes a statement for the White attack, but only after the dubious 5...c5?! as pointed out by <AdrianP>. |
However, after the standard 5...d6 reply, Black with precise followup may be able to undermine the White center and score with a winning counterattack as in Fritz vs Anand, 1997 Yet, White still has his chances after 5...d6 as his extended center and active piece play can generate a winning passed pawn as in Lautier vs Ian Rogers, 1996 or secure enough counterplay to hold for a draw against a higher rated opponent as in Lautier vs Kasparov, 1995
Kasparov and Keene summarized the case well in BCO when they wrote the King's Indian Defense Four Pawns Attack (5 f4) "is a volatile weapon, it can often backfire, and should only be chosen by those who relish living dangerously."
|Dec-23-08|| ||WhiteRook48: Geller overdid it.
Don't seek complications.
|Sep-18-12|| ||Honza Cervenka: 5...c5 is probably inferior to solid 5...d6 but it is playable. 8...Qxc5 was the losing move.|
|Jul-16-13|| ||whiteshark: Ouch!|
|Jul-26-15|| ||Pirandus: I dont understand.|
