1/15/2003 15:35:40 play online chess | Subject: Can anyone offer some analysis?
Message: Here is a game I played recently that ended in an agreed draw. There are a lot of places where I was very uncertain as to the right way to proceed, and I also don't know if it was right/wrong/lucky to accept the draw at the end. Would anyone like to add some annotations? I am looking for something a bit beyond running it through a computer engine looking for tactical shots (which I already did)
Thanks a lot,
Mike

Since White has played already played Nbd2, I don't like this move much. Nbd2 has the potential to at least be a bit awkward for White if he's trying to complete his development, and the upcoming exchange on f3 resolves this issue for White immediately (and favorably). Without Nbd2, ...Bxf3 is usually okay since White either has to recapture with Bxf3 (losing time, since White will likely have to play the bishop back to g2 at some point) or Qxf3 (which isn't an ideal post for the queen). I prefer an immediate 9... b5 .
10. h3 Bxf3
10... Bd7 is probably better, for reasons given previously.
11. Nxf3 b5 12. Nh2
With ...Rb8, Black is clearly signaling that he intends play on the queenside. Following the classical "rule", a thrust in the center is called for as a counter to flank action so either 12. d4 to set up a two abreast pawn center or 12. e5 to free the g2-bishop is a promising idea. e5 is a typical pawn thrust in King's Indian Attack-type setups anyway.
12... b4 13. d4 Qb6
Premature. 13... bxc3 14. bxc3 cxd4 15. cxd4 Qd7 prepares to shift more pieces to the queenside.
14. d5
14. e5, when 14... dxe5 15. dxe5 Ne8 and 14... Nd7 15. e6 fxe6 16. Qb3 are slightly better for White.
14... bxc3 15. bxc3 Ne5 16. Bf4
The blockade on e5 cannot be allowed to remain or else the g2-bishop gets locked out of play. 16. f4 (another common thrust in such positions, supporting e5) Ned7 17. e5 Ne8 18. Nf3 and White's central play is pitted against Black's queenside play.
16...Nfd7
White's central play is shut down while Black's queenside play continues. Black stands better.
17. Qc2 Qa5 18. a4
Perhaps 18. Reb1 to try to challenge Black's attempt to dominate the queenside.
18... Nc4 19. Ra2 Qxc3
An attempt to cash in that doesn't really work. 19... Rb7 prepares to increase the pressure on the queenside.
20. Qxc3 Bxc3 21. Rc1 Rb3 22. Rac2 Bb2 23. Rc2xc4 Bxc1 24. Rxc1 Rfb8 25. Nf3 Rb8b4
25... Rb1 exchanges off a pair of rooks, making it difficult for White to contest Black's control over the b-file, giving Black his fair share of play on the queenside. Still, White would have play in the center.
26. e5 dxe5 27. Nxe5 Nxe5 28. Bxe5 c4
Trading a pair of rooks with 28... Rb1 29. Rxb1 Rxb1+ would have at least given Black real chances of counterplay on the queenside.
29. Bf1
Just in time.
29... Rb3b1 30. Rxb1 Rxb1 31. Kg2 Rb4
31... Re1, attempting to drive the bishop off the long diagonal so as to make ...c3 a threat.
32. a5 Ra4 33. a6 Rxa6 34. Bxc4 Ra4 35. Bb5 Ra5
35... Ra2 to get the a-pawn rolling, giving White something to think about.
36. Bc6 Ra3 37. Bc7 Rc3
37... a5 is a bit better.
38. Ba5 Rb3 1/2-1/2
Hmmm... well, this endgame is probably drawn, but I would have chosen to play on since I think White has genuine winning chances.

Message: I was starting to analyze this, but caldazar did a great job so I won't even try. I'll just add a few comments to his:
12. d4 gives White a clear advantage in the two bishops and Black's misplaced rook, better than 12. e5 which leads to a roughly equal position after 12... dxe5 13. Nxe5 Nxe5 14. Rxe5 Nd7. 12. Nh2 signals the beginning of a faulty plan to play f4 which doesn't work because the center is still in flux.
The comments after 14. d5 are a bit confusing. After 14. e5 White is clearly better because 14... Nd7 just leaves the knight hanging to 15. Qxd7. Furthermore, 14. e6 fxe6 15. Qb3 is bad because it allows Black's rook to enter the game and Black is actually winning after 15... c4, with a threat both on the Queen and on f2.
16. f4 is clearly indicated but needs a little bit of tactical analysis: 16... Nc4 (the only logical move) fails to 17. e5 dxe5 (17... Nd7 18. Qa4) 18. Qe2 Qb5 19. Bf1 Nd6 20. Qc2 Qd7 21. fxe5.
After an ...Rb1 by Black, the game is probably a dead draw. When playing up an exchange or with a rook for two pieces, a player should generally try to trade off the pair of rooks because the other player will usually not be able to contest adequately on ranks and files. Conversely, the player with the sole rook should try to keep it on the board.
And finally, 29. Bf1 is a mistake: 29. Be4! leaves white clearly better, permanently preventing ...Rb1 and not allowing 29... Rxa4 in view of 30. Bc2. Moves like 29... c3 fail to 30. Bc2 Ra3 31. d6 exd6 32. Bxd6. Black has to settle for something like 29... f6 30. Bf4 Kf7, barely holding, but White is clearly superior and has real winning chances.

Chess news:
Can Karpov Be President of Chess Federation? -- The former world chess champion Anatoly Karpov announced on Saturday that he was running for president of the World Chess Federation. Karpov is trying to unseat Kirsan Ilyumzhinov, who has been president of the federation (known as FIDE, its initials in French), since 1995. Ilyumzhinov is also the president of Kalmykia, a small Russian republic on the Caspian Sea. The federation president is elected for a five-year term, and there is no limit on how many times he (or she) can be re-elected. Karpov would not be the first ex-champion to serve as FIDE’s president. Max Euwe, the fifth world chess champion (1935-37), led the federation from 1970-78, a period of exceptional ...
Ivanchuk, Carlsen Lead at Amber -- Rapid chess and blindfold chess require different skills. But excelling at both is a prerequisite for victory at the annual Amber Chess Tournament, the most unusual event of the year. Amber is sponsored by Joop van Oosterom, a Dutch billionaire and world correspondence chess champion, who started the tournament in 1992 and named it after his daughter. With a generous prize fund (this year 216,000 euros, or a little less than $300,000), an invitation to the tournament is coveted by the world’s top chess players. (It does not hurt that the tournament is held in Nice, France, on the Côte d’Azur.) This year’s field is made up of ...
In Europe, a Young Chess Champion Emerges From Deep Ranks -- The European Championships showed how much the chess world has changed in the last 20 years. The men’s division was won by Ian Nepomniachtchi of Russia, a 19-year-old chess grandmaster. Nepomniachtchi is talented, and he was seeded 35th in a field that included more than 150 grandmasters. But he was just one player among dozens who had a realistic shot at the title. On the scale used to measure ability, Nepomniachtchi has a rating of 2,656 and is ranked No. 78 in the world. Yet in 1990, Yasser Seirawan of the United States — one of the most talented chess players of his generation — was 10th with a rating of 2,635. Now, Seirawan’s rating is 2,651, and he is ...
