  tamar: It does look like there is a way to infiltrate the King to b1 with the Rook on d5 monopolizing the bishop and King.

But Nakamura does not look especially sure at the board.

  tpstar: Watching this endgame for a while, I think the doubled Pawns really sap Black's winning chances. The safest course is 62 ... Rd2 & 63 ... Rxa2 keeping the draw in hand, then centralizing the King to attack the Pe5 and the Pc3. But White should still hold.
Nov-10-10  Ulhumbrus: It seems that the move 62 ..Rd1 prepares the move 63...Re1.
Nov-10-10  Ulhumbrus: White's King is on the eighth rank. With respect to the c3, c5 and a2 pawns, Black may end up playing with an extra King.

Nov-10-10  Marmot PFL: Surprised to see this game still going.
Nov-10-10  Ulhumbrus: Perhaps Nakamura wants to prepare the move ...Kc4 by playing his bishop to d5.

Nov-10-10  Ulhumbrus: Suppose that instead of 73...Kc4 Black tries 73..Rxa2 74 Rxa2 Bxa2, with White's B on d6 instead of on f6. This may win for Black.

  tpstar: 1) Call his cellphone.

2) Lock him out so he loses on time.

3) Tell him Kasparov just got funding for their WC match.

4) Persuade him to withdraw in protest because the World Champion doesn't deserve any privileges.

5) 1 ... Kc4! 2. Kxf7 Kxc3+ 3. Bxc5? Bxf7 0-1.

  chessgames.com: That's all for today, thanks for coming. The next round is tomorrow morning at 7:00am USA/Eastern. Hope to see you then!
Nov-10-10  Ulhumbrus: <tamar:> How about this: Play ...Bd5, ...Kc4, ..Kxc3 and then run with the other c pawn
Nov-10-10  el nanes: This is a draw!!. Players should always fight it out til the end as you never know wether your opponent will play flawless all the way. At this level a slight inacurracy can be decisive. They should forbid draws before move 40. Considering the depth of preparation nowadays it an insult to the public to draw before move 30.

  Sastre: <Ulhumbrus: <tamar:> How about this: Play ...Bd5, ...Kc4, ..Kxc3 and then run with the other c pawn> 73...Rxa2 74.Rxa2 Bxa2 75.Ke7 Bd5 76.Kd7 Kc4 77.Kc7 Kxc3 78.Bxc5 Kc4 79.Kd6 should be an easy draw for Black.
Nov-11-10  Ulhumbrus: <Sastre: <Ulhumbrus: <tamar:> How about this: Play ...Bd5, ...Kc4, ..Kxc3 and then run with the other c pawn> 73...Rxa2 74.Rxa2 Bxa2 75.Ke7 Bd5 76.Kd7 Kc4 77.Kc7 Kxc3 78.Bxc5 Kc4 79.Kd6 should be an easy draw for Black.>

Then Black cannot run with the c6 pawn after offering the c5 pawn and White does bring his King into play in time.

Yet Black seems to play a king ahead for at least some purposes, because what is White's King doing on the Queen side?

One answer is that Black's King requires at least a few moves to win the c3 pawn and White's King gets into play in that time.

Another more interesting answer is that Black's Queen's bishop is overworked. If it has to defend the f7 pawn, it cannot allow itself to get captured on a2 as well.

So we have this interesting paradox: White's King, by attacking the f7 pawn on the King side, defends the Queen side because he prevents Black's Queen's Bishop from talking the a2 pawn and inviting the sacrifice Rxa2! removing the piece defending the f7 pawn which keeps back the e6 pawn.

It is conceivable that Black can win by some alternative elsewhere. It remains to be seen whether one of the published commentaries suggests one.
