The Daily Update: Biel Comes Alive! Plus Adams, Morozevich Roll On - and More
1. I doubt any of the competitors at Biel read my blog, but it's likely that the sorts of sentiments expressed here about their consistent non-play have been expressed by many others. Perhaps this weighed on their consciences or provoked the organizers to harangue them. Whatever the story, something happened and they FINALLY played some real chess today. It was excellent! All the games were hard-fought, four of the five games finished in a win, and the only draw was a real battle and the last game to finish.
Vachier-Lagrave - Rodshtein 1-0
Andreikin - Caruana 1/2-1/2
Giri - So 1-0
Tomashevsky - Nguyen 0-1
Howell - Negi 1-0
Vachier-Lagrave - Rodshtein was a Gruenfeld that generally saw things going White's way, but the game was decided after 35...Rxe6?? (35...Rg8! 36.Qxh7+ Kf8 favors White, but Black is very much alive). White could have won more easily than he did, but Black was never able to completely extricate himself.
Andreikin - Caruana was a quasi-Rossolimo turned Open Sicilian turned quasi-French, but through all the twists and turns the position remained fairly even. Caruana gradually obtained a slight initiative, but in the end it was only enough to force a draw by repetition.
Giri - So was decided in a queen ending. So's clever 19...Bxh3!? led to that ending, where White was slightly better but a draw looked the likeliest result. The game was decided when So chose 34...f4?! 35.Qh4 Qxh4?, voluntarily transposing into a lost king and pawn ending. No doubt So missed White's triangulation maneuver on moves 42 and 43, but it was a bad risk to enter the pawn ending in the first place. Live and learn.
Tomashevsky - Nguyen was bad for White almost from start to finish. The ending - from move 35 on, say - was quite interesting, in that White desperately wanted to eliminate Black's d4-pawn while Nguyen kept finding ways to keep the pawn alive and meaningful. Black succeeded, and in the end White's preoccupation with the pawn left him unable to cope with threats to his king.
Howell - Negi saw the "Botvinnik System" of the 2.c3 Sicilian. Black was doing fine, but his plan of doubling rooks on the d-file followed by 26...Rd3 ingeniously forced White to beat him. White had no choice but to sac the exchange, and the result was a position where Black had no meaningful active possibilities whatsoever while White could try this and that. Soon White's position was not only easier to play but simply winning, and Black forced him into it!
With eight rounds down and one to go, the standings look like this:
1-2. Vachier-Lagrave, Caruana 5
3-4. Nguyen, Andreikin 4.5
5-8. Giri, So, Tomashevsky, Rodshtein 4
9. Howell 3
10. Negi 2
The last-round pairings:
Rodshtein - Tomashevsky
Negi - Vachier-Lagrave
Caruana - Howell
So - Andreikin
Nguyen - Giri
It's not likely, as the leaders are playing tailenders, but it's possible to have half the field tie for first.
2. The British Championship: It had its first GM vs. GM pairing, with Adams taking on Summerscale. Of course, not all GMs are equally strong, and Adams outrated his opponent by more than 200 points and won quickly. Quite a few of his main rivals drew their games, so although it's still very early the tournament is shaping up nicely for him.
3. The 4th AD San Juan International in Pamplona is up to round 4 today, but only the games and results through round three are available as of this writing. Morozevich leads with 2.5/3.
4. Finally, the Houdini 1.03a - Stockfish 1.8 match continues, and after 22 games Houdini leads 12.5-9.5. Stockfish won game 1, Houdini games 2, 11, 12 and 17. The games have been more accessible, I think, to human eyes, thanks to the opening selection this time around, but the percentage of draws has been very high. Is the moral that the more theoretical the opening, the more objectively drawish the position? I'm not sure. After all, the Rybka 4 - Houdini match wasn't terribly theoretical in its opening selection, but the drawing percentage was high there as well. Maybe Houdini's "style" leads to a greater than average number of draws? Those with access to more data might have something more intelligent to say about this matter.
