[lang_nl]R3: Zeven remises (4e update)[/lang_nl][lang_en]R3: Seven Draws (update 4)[/lang_en]
[lang_nl]Ronde 3 is inmiddels aan de gang. Loek durft, want hij volgt Radjabov-Anand en we weten hoe dat afliep. Misschien dat hij wat heeft liggen van Mexico? Aronian heeft nu al een pion geofferd en Mamedyarov heeft zowaar 1.e4 gedaan tegen Kramnik. Video's + Dvoretsky-analyse toegevoegd[/lang_nl][lang_en]We're looking at round 3 and Loek apparently has no fear, since he's following Radjabov-Anand and we know how that ended. Perhaps some Mexico material was lying on a shelf? Aronian has already sacrificed a pawn and Mamedyarov is trying it with 1.e4 against Kramnik. Videos + Dvoretsky analysis added[/lang_en]
[lang_nl]Update 16.01h
Twee vroege remises zijn al gevallen: Eljanov-Anand en Mamedyarov-Kramnik. Eljanovs 11.g4 vond Anand er wat riskant uitzien maar hij kon het in de partij niet aantonen. In de post-mortem gaf hij nog aan dat hij op 11...Dd5 12.dxc5 er vervelend vond uitzien, vanwege 12...Dxc5 13.Dxc5 Pxc5 14.g5. De echte fighting spirit moet nog komen bij Vishy. Mamedyarovs zijvariant tegen Kramniks Russisch leidde al snel, net als bij de bovenstaande partij, tot een eindspel met ongelijke lopers waarin weinig muziek meer zat. Dit eindspel komt voor de derde keer voor in Polgar-Topalov, maar laatstgenoemde heeft genoeg reden om door te spelen vanwege de zwakke witte pion op a5.
Aan het begin was er enige consternatie in de perskamer, aangezien Ivanchuk 50 (!) minuten nadacht na zwarts derde zet. Inmiddels staan de klokken bijna weer gelijk in een eindspel met twee torens en een loper (voor wit) tegen een paard. Wit heeft een plusje zo lijkt. Carlsen haalde weer eens een Open Spanjaard van stal tegen Adams, en ook hier ongelijke lopers maar nu met de dames er nog op. Vanwege de vrijpion hebben we liever wit.
Leko heeft de pion op het juiste moment teruggegeven aan Aronian om een veilige afwikkeling te kunnen garanderen. Dit wordt snel remise vermoedelijk. Loek doet het prima tegen Radjabov; inderdaad zag zijn voorbereiding er uitstekend uit (en over de eerste 21 zetten had hij slechts 19 minuten nodig). Het eindspel is gewoon prima voor zwart; de vraag is of hij het kan winnen.
In de overige groepen nog geen uitslagen maar wel leuke potjes. Komen we op terug.

Update 19:01h:
Loek probeert naarstig een eindspel te winnen dat erg lastig te winnen is. Hier is een analyse van Dvoretsky uit zijn geweldige boek Dvoretsky's Endgame Manual:
En check ook de Nalimov Tablebase website waar je de exacte stelling kunt bekijken.
Update 20:15h
Radjabov verdedigde erg goed en dus eindigde ook de laatste partij in remise. Een grote verrassing in groep B was de harde overwinning van Hou Yifan op Nigel Short en een andere kleine (maar fijne) verrassing was Smeets die top seed Cheparinov in het verre eindspel versloeg. De Nederlander leidt nu samen met Bacrot. In groep C staan alleen Caruana en Braun nog op 100%.
Helaas was er vandaag geen persconferentie.[/lang_nl][lang_en]Update 16.01h
Two early draws: Eljanov-Anand and Mamedyarov-Kramnik. Eljanov's 11.g4 looked a bit dangerous according Anand but he couldn't prove it in the game. During the post-mortem he said he refrained from 11...Qd5 because of 12.dxc5 Qxc5 13.Qxc5 Nxc5 14.g5. Vishy's real fighting spirit isn't there yet. Mamedyarov's sideline against Kramnik's Petroff quickly led to the same type of ending as the just described game: opposite-coloured bishops and rooks, without much music left. This was reached for a third time today, in Polgar-Topalov, but the latter has more reason to play on because of the weak pawn on a5.
During the first hour Ivanchuk surprised everyone by thinking for 50 (!) minutes after Black's third move. In the meantime the clocks are almost even in an ending with two rooks and a bishop (White) against a knight. White has a plus it seems. Carlsen opted for an Open Ruy against Adams, and here too we see opposite-coloured bishops, but with queens still on. Because of the passed pawn we prefer White.
Leko has given back his extra pawn at the right moment to be able to safely liquidate. This will soon end in a draw. Loek is doing fine against Radjabov; indeed his preparation looked more than OK (for the first 21 moves he only needed 19 minutes). The ending is just great for Black; the question is whether he can win it.
No results yet in the other groups but surely some interesting fights. More about that later.

Update 19:01h:
Loek is trying to win an ending that's very difficult to win. Here's an analysis by Dvoretsky in his great book Dvoretsky's Endgame Manual:
And do check Nalimov Tablebase website in which you check on this position exactly.
Update 20:15h
Radjabov defended very well and so the last game ended in a draw as well. A major upset in group B was Hou Yifan crushing Nigel Short and another slight surprise was Smeets beating top seed Cheparinov. The Dutchman now leads together with Bacrot. In group C, only Caruana and Braun are left on 100%.
Unfortunately today there was no press conference.[/lang_en]

According to the tablebase website the position was all the time drawn. Radjabov played a few 'only moves'

Dear sirs,
Many nice things can be said for your efforts. Bravo! Can you add also the chess - boards of the running games - as photos and videos?
Kind regards D.Kostakiev

Yeah Hou!
What I like about her is that, following my impression, she's not playing passive and defensive but has a fresh agressive style; hope it's not only the courage of her youth but really her playing style. Or am I wrong?

Arne, you are right of course. The discussion reminds me of the ancient theological discussion about the status of God. Is God allmighty? And if He is, can God make a stone that is too heavy for him to lift?

Radjabov se ha escapado de milagro. A ver si en la ronda 4 tenemos partidas mas emocionantes.

@Ron, you probably mean: even God cannot wins the position *against perfect play*. Quite an important distinction, I should say.

Hey Peter,
you made a mistake with the results, it's Y.Hou - N.Short 1-0 and not the opposite! You probably couldn't believe her victory! ;)

The ending in Radjabov - Van Wely is similar to the ending Velimirovic-Timman in the Candidates in Rio de Janairo in 1978. The way to victory is decribed in Chiron's famous ending books. It caused a hype then in the Netherlands after Donner wrote about it in the Volkskrant. The game was adjourned and Timman found the difficult way to a victory.

Wasn't it the case that Ch?ɬ©ron's method of winning was too long, and Timman had to find a faster way?
DokterSpock

Yes, Velimerovic made a few inaccuracies that helped Timman, so the 50 move rule didn't come into practice. I think also because of Timmans game FIDE invented the 75 move rule for this ending and a few others. Indeed, it is Cheron and not Chairon, as I wrote. I have the book and checked it now.

Van Wely admits he forgot the correct way (Re4) and lost some moves now.

The correct way is quite counterintuitive; you'd think you'd have to drive away the K from the pawns...

I thought I remeber you had to get the WK on the g-file to win that one extra tempo.

I predict that in this tournament Radjabov will be the player who made the largest number of moves.

Yes that's what I thought, white K to the g-file (or the h-file, just in case!) etc., so the Maizelis line given in the post surprised me.

Radjabov has a big lead in the "number of moves" competition: 85 in round 1, 79 in round 2, and now he can claim a draw at move 95, it seems...

Van Wely needs an extra tempo, This is a draw.

According to the tablebase, the position after 45...Txh4 46.Kc2! is a draw. So Loek doesn't have to be sad if he doesn't win this endgame. Even God cannot win that position (unless, of course, the Almighty messes with his opponent's brain, changes the rules etc.).
