Experimenting or not ? that is the Question! - 2007/07/13 15:14
Certain chess games sometimes resemble a dramatical scenario, with a tense setting, a definite plot and of course a surprising finish. But in contrast to the theatre, in a chess game there are simultaneously two authors, who are also the script writers, director and actors.
In order to “strike gold”, they often have to work in one direction hand in hand so to speak, so as then to try and catch each other in a trap.
Of course, it by no mean always happens that a prepared variation causes a genuine revolution and radically changes an established diagnosis. More often, prepared surprises are experimental and do not pretend to the absolute truth. Their aim is for some period of time to pose a number of serious problems, the solution to which cannot always be found quickly, years sometimes passing before the answer is forthcoming.
New and original ideas in the opening do not simply arise out of nothing. It is not enough to know and understand opening strategy one must in practice be able to put it in action.. To win an opening battle one must learn to acquire the gift of finding at times the only paths where there is a fruitful ground for the “germination” of fresh ideas, and where there is freedom for the experimenter’s character to manifest itself. Garry Kasparov was a striking example of one of the most profound of modern chess theorist.
The Kasparov-Karpov Sicilian duel had provoked many disputes. Especially in their second match, Moscow 1985 when Kasparov twice employed the gambit which now in theory bears his name.
During his preparation for the match, the challenger devised this interesting innovation, and spent a great deal of time on a detailed analysis of the resulting possibilities and on positionally substantiating his idea. Sacrificing a pawn by 8. … d5, black does not aim for material equality it is more important for him to mobilize his forces and seize the initiative. When he first encountered 8. … d5!? In the 12th game Karpov decided not to take any risks and chose a quiet continuation leading to a draw. But then in the 16th game he accepted the challenge ( the match situation obliged him to ) and a genuine chess battle developed. But Kasparov’s home preparation proved much deeper….[/b]
[b]Karpov-Kasparov Moscow 1985
1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nc6 5.Nb5 d6 6.c4 Nf6 7.N1c3 a6 8.Na3
A well-known position, where opening guides recommend that Black should continue his development with 8. … be7 9. Be2 0-0 10. 0-0 b6 or 10. … Bd7
Kasparov employs a sharp gambit variation.
8. … d5!?
This move was first made in the game honfi-Dely Hungarian Championship,1965, where events developed as follow 9.cxd5 exd5 10.exd5 Nb4 11.Qa4+ Bd7 12.Qb3 Be7 13.Bf4 Bg4 14.f3 Nfxd5 15.Nxd5 Nxd5 16.fxg4 Nxf4 17.Qa4+ b5 18.Qxf4 0-0
For the sacrificed piece Black has a dangerous initiative.
9.cxd5 exd5 10.exd5 Nb4 11.Be2
in the 12th game of the match Karpov chose 11. Bc4, and after 11. … Bg4 12. Be2 Bxe2 13. Qxe2+ Qe7 Black quietly equalized.
11. … Bc5
11. … Nbxd5 favours white, since after 12.Nxd5 Nxd5 13. 0-0 Be7 14. Bf3 Be6 15. Nc2 he has the better development.
12.0-0 0-0
12. … Bf5 would appear to transpose after 13. Bf3 0-0 while preventing 13. Nc2. But in fact this is not so, since white has the strong reply 13. Nc4, and if 13. … Nc2 14. Ne3!
13. Bf3
White incorrectly uses his pieces to defend his extra pawn which will soon merely be in his way. 13. Nc2 look sounder but even after 13. .. Nbxd Black has everything in order. 13. Bg5 also fails to give white an advantage, on account of 13. … Bf5 14. Nc4 Nbxd5 15. Nxd5 Qxd5 16. Bxf6 Qxd1 17. Rfxd1 gxf6 with an equal endgame.
13. … Bf5 14.Bg5
14. Nc4 does not achieve anything, since if he wishes Black can force a draw by 14. … Nc2 15. Rb1 Nd4 or even gain a slight plus with 14. … Bd3 15. Be2 Bxe2 16. Qxe2 Re8 17. Bf3 Nfxd5.
14. d6 is very strongly met by 14. … Qd7! But not 14. … Bxd6 on account of 15. Nc4 and if 15. … Bxh2+ 16. Kxh2 Qc7+ 17. Nd6 Nd3 then 18. Bf4! Nxf4 19. Nxf5 when white emerges a piece up.
14. … Re8
Black has also a sharp continuation 14. … Bd3 15. Re1 Ng4!?, but white would have refuted it after 16. Bxd8 Nxf2 17. Qd2! Nh3+ 18. Kh1 Nf2+ 19. Qxf2 Bxf2 20. Be7 Bxe1 21. Bxf8 Bxc3 22. bxc3 ect.
15.Qd2 b5
black is playing to restrict his opponent pieces
16. Rad1
White might as well given up his d-pawn to activate his bishop at f3.
16. … Nd3 17.Nab1
The white knight are driven back and become passive, whereas the black pieces begin operating at full capacity
17. … h6 18.Bh4 b4 19.Na4
Playing towards the centre by 19. Bxf6 Qxf6 20. Ne4 does not work on account of 20. .. Bxe4 21. Bxe4 Bxf2 And in the event of 19. Ne2, white would have to reckon with 19. … g5
19. … Bd6 20.Bg3 Rc8
Black brings up his last reserves.
21. b3
21. … g5!
This strong pawn move on the kingside prevents 22. Nb2, in view of 22. … Nxb2 23. Qxb2 g4 24. Be3 Rc2
22.Bxd6 Qxd6 23.g3 Nd7 24.Bg2
the best chance for white was 24. Nb2, when after 24. … N7e5 25. Bg2 Qb6 26. Nxd3 Nxd3 he appears to end up in positional zugzwang but by continuing 27. d6 Qxd6 28. Rfe1 he obtains some hopes.
24. … Qf6 25.a3 a5 26.axb4 axb4 27.Qa2 Bg6
Black avoids the plausible 27. … Nf4 since after 28. gxf4 Rc2 29. Nb2 Rxb2 30. fxg5 hxg5 31. Qa4 whites gains counter play.
28. d6
the d-pawn is not required by white. He needs to coordinate his forces as soon as possible especially his knights
28. … g4
After 28. … Qxd6 white could have defended by 29. Nb2 Rc2 30. Rd2
29.Qd2 Kg7 30.f3 Qxd6 31.fxg4 Qd4+ 32.Kh1 Nf6
Black activate his pieces to the maximum and at the same time create irresistible threats of … Ne4
33.Rf4 Ne4 34.Qxd3 Nf2+ 35.Rxf2
On 35. Kg1 the simplest would have been 35. .. Nh3+ 36. Kh1 Qxd3 37. Rxd3 Re1+
35. ... Bxd3 36.Rfd2 Qe3 37.Rxd3
The three scattered minor pieces are no match for the queen
37. … Rc1 38.Nb2 Qf2 39.Nd2 Rxd1+ 40.Nxd1 Re1+ white resigned
Just a few month after that match , Karpov while playing van der Wiel in Brussels finally employed drastic measure which cast doubt over Kasparov experiment
Playing white against van der Wiel instead of 12. 0-0 Karpov chose the unexpected 12. Be3! Bxe3 13. Qa4+!
It now transpires that in the event of 13. … b5 14. Qxb4 Bb6 15.0-0 Ba5 comes the sacrifice 16 Bxb5+ axb5 17 Rfe1+ with a very strong attack.
The game continued 13. … Nd7 14. Qxb4 Bc5 15. Qe4+ Kf8 16. 0-0 b5 17 Nc2 Nf6 18. Qd3 when white retained both a good position and a “good“ extra pawn.
Did Kasparov know at that time that his innovation was defective? It is hard for me to judge,. Perhaps he had some counter-argument against white’s improvement and saw a fighting for equality, or else somewhere he found an inferior position which was drawn?
During preparation for a game it often happens that an interesting idea occurs to you. And even if you are not firmly convince, there is a great desire to try out your discovery. But when the inventor employs it in practice, sometimes he himself sees a possible refutation….
