Jan-30-11  Marmot PFL: < Ulhumbrus> I would play on a while, but these guys see so much they don't need to.
Jan-30-11  talisman: good morning...draw.
Jan-30-11  vanytchouck: Draw agreed ???
Jan-30-11  Open Defence: < fisayo123: The engines give a decisive advantage to Anand.Can you trust engines in this position?> possibly not, run them in multi pv mode and if the eval is the exactly the same for a number of alternative and even for playing through the lines it might be just a drawn position thats being misevaluated due to the material imbalance
Jan-30-11  arkansaw: can't White simply shuffle the knight between a5 and c6?

but I can see a plan of keeping white's king on g1 (to prevent h file entry), then taking on a5 at the right moment and exploit the possibility of b pawn queening with checkmate.

Jan-30-11  fisayo123: All the engines showed no progress,a draw was the logical outcome.congrats Hikaru.
Jan-30-11  arkansaw: but anyway, a great start to the year for Nakamura. Next to become world champion while Carlsen slacks away
Jan-30-11  belgradegambit: Looks like a dead draw to this patzer. This is the kind of position that computers really fail at. They shuffle their pieces and find a material advantage at the end of a line without any plan.

  patzer2: Interesting final position. My older Fritz version shows it as a winning advantage for Black, but can't find any way to capitalize on the exchange.

Congratulations to Nakamura on winning the tournament.

Jan-30-11  Marmot PFL: <The king is controlling the potential invasion squares. How can you win? Even if Black, let’s say, brings his king to d6 using zugzwangs. What next? If the king has to stay rooted to the spot, then the knight can switch from c6 to a5, and back again.> Shipov comment. I saw that too, but would have played to that postion then thought some more before a draw.
Jan-30-11  belgradegambit: Naka with sole possession of 1st place!!
Jan-30-11  Ulhumbrus: <Marmot PFL:> One interesting idea is to play the pawn sacrifice ...a5 with Black's K on d6 and the Black R on c7. Then bxa5 allows the Black King to invade White's position by ...Kc5 while Nxa5 allows the Black Rook to invade White's position along the c file. Perhaps this is Anand's plan.
Jan-30-11  Marmot PFL: <Ulhumbrus> That's what i thought too cause the WK on g1 is so far away.
Jan-30-11  The End: If Aronian wins..I think next rating list should look like this.. Anand 2816 Carlsen 2815 Aronian 2814
Jan-30-11  arkansaw: most fireworks have ceased quickly in group A, with exception of Aronian still looking to steal a few more elo from Smeets
Jan-30-11  Marmot PFL: <The World Champion has simply convinced himself that White’s fortress is unassailable, and offered a DRAW, which was accepted. There might follow:

39. Kg1 Rh7 40. Na5 Ke7 41. Nc6+ Kd6 42. Na5 and Black can’t break through. So… well done, Ian – he held a difficult position. And Hikaru Nakamura has become the sole winner of the Wijk-aan-Zee 2011 super-tournament. Bravo!>

  Domdaniel: <Arkansaw> - < I can see a plan of keeping white's king on g1 (to prevent h file entry)> That almost works, but the Rook can't be in two places at once - both threatening to penetrate on the h-file and switching to the other wing to threaten mate on an open file (as in 39.g1 Rc6 40.Na5?? Rc1#, to put it crudely).

White can deal with both threats, by Kg1-f1-g1 when the Rook leaves the h-file, and Na5-c6 when the Rook isn't threatening mate.

Jan-30-11  Ulhumbrus: <<Marmot PFL:> One interesting idea is to play the pawn sacrifice ...a5 with Black's K on d6 and the Black R on c7. Then bxa5 allows the Black King to invade White's position by ...Kc5 while Nxa5 allows the Black Rook to invade White's position along the c file. Perhaps this is Anand's plan.> Perhaps Anand has rejected this plan because after bxa5 White threatens a6 followed by a7 and Nb8 as well as d6. In that case one question is whether after 38...gxf3 39 gxf3 Black can support the invasion ...Rg2 by playing his King to h3. However either the Black King or the Black Rook appear tied to the defence of the pawn on e5, and if that is the case, Black can't break through.
Jan-30-11  turbo231: I wish they had a web cam on site, we'll have to wait until tomorrow to see the celebration, unless some other site has a web cam.
