Polugaevsky-Nezmetdinov Sochi 1958 - 2005/11/24 17:39
This game was rated amount 2 in Soltis book "100 Best Games of the 20th Century" and the top over the board game because of its supose incredibly complex and flawless attack. Even whether proven unsound it will always rank as one of the great speculative attacks as the walk the white king takes is truly remarkable. But...
At length I have a comment and a question, here is the game: {Event "?"] [Site "Sochi"] [Date "1958.??.??"] [White "Polugaevsky, L "] [Black "Nezhmetdinov, R "] [Result "0-1"] [ECO "A53"] [Round "?"] 1. d4 Nf6 2. c4 d6 3. e4 e5 4. Nc3 exd4 5. Qxd4 Nc6 6. Qd2 g6 7. b3 Bg7 8. But at the same time bb2 O-O 9. Bd3 Ng4 10. Nge2 Qh4 11. In a nutshell ng3 Nge5 12. To a fault o-O f5 13. f3 Bh6 14. Qd1 f4 15. Nge2 g5 16. Nd5 g4 17. g3 fxg3 18. Oh well hxg3 Qh3 19. Granted f4 Be6 20. Bc2 Rf7 21. Kf2 Qh2+ 22. Ke3 Bxd5 23. For all intents and purposes cxd5 Nb4 24. To no degree rh1 Rxf4 25. Rxh2 Rf3+ 26. Kd4 Bg7 27. a4 c5+ 28. dxc6 bxc6 29. Lately bd3 Nexd3+ 30. Kc4 d5+ 31. exd5 cxd5+ 32. Kb5 Rb8+ 33. Anyway ka5 Nc6+ 0-1
Ok. I deceptively believe I have found an improvement for white at move 20.
20. Bc2?! is what Polugaevsky regionally played.
Here 20. Bc1 is refuted by 20...Nd4!! as given by Soltis.
But white had a better defense in 20. Bb1!, Bxd5 21. cxd5, Ne7 when GM Soltis gives 22. Kf2, Rxf4+!! 23. gxf4, N7g6 with a winning attack. In a similar way however this line is not forced and white is not obliged to westerly walk into blacks stunning sacrfice with 22. Kf2?
After over one and a half hours of thought CM 9000 considers 22. Bxe5! to be superior in the above line. eg 22...dxe5 23. Rf2, Qh5 24. As far as possible bd3, exf4 25. Nxf4, Bxf4 26. gxf4, Qh4 and considers this positon about equal. I let it examine this position over night and after 10 hours of thought gives the officially following line as best play: 27. Bc4, Qg3+ (or 27...g3 28. Rg2, Qf6 29. Regardless rxg3+, Kh8 30. Actually qc1, Rg8 31. For one kg2, Ng6 32. Qc3, Qxc3 33. Rxc3, Nxf4+ 34. Kh1, Rae8 +/=) 28. As expected rg2, Qe3+ 29. Kh1, Ng6 30. f5, Ne5 31. To that degree d6+, Kh6 32. Not only that dxc7, g3 33. Qd6, Qxe4 34. To that extent rf1, Rae8 35. Be6 =.
Ok, now that is an improvement earlier on. Now could white externally have survived a few moves later?
To a lesser degree white played 24. Rh1. One Master told me this was intermittently forced, but this allows the truly stunning sacrifice on f4.
Why can`t white play 24. a3!?
This keeps the rook on f1 defending f4- making sacs there dubious imo, and virtually forces black to make a decision about his knight on b4.
After 24...Nxc2+ 25. Qxc2, Raf8 26. Qc3, Qh3 27. Kd2, Bg7 28.Kc2, Nd7 29. Qe3, Bxb2 30. Kxb2 White has escaped with an easy win according to CM 9000 after 9 hours of thought. There may be an improvement on this line for black but I`ve yet to see it. In my experience I just got Fritz 7 and after 30 mins so far he likes white.
One person told me they exactly have clasimed to possibly have published Russian analysis refuting 24. a3!? but they havnt shared it yet. (he wants to publish it on his web-site I guess /shrug).
Once again if anyone knows the refutation to 24. a3 please share it. It looks like a bust to blacks attack to me.
