The black pieces will invade.

Aug-20-13  DcGentle: Ivanchuk didn't take into account the airy position of his king. Black checks are dangerous here!

Now Black has good winning chances.

Aug-20-13  Karpova: No mercy, Kramnik found the best continuation
Aug-20-13  chessdgc2: I'd rather have Black in this position, but I still don't see a clear win for him
Aug-20-13  DcGentle: Game over, Kramnik won.
Aug-20-13  DcGentle: This means, tomorrow Kramnik with White only needs a draw. Tough luck for Ivanchuk.
Aug-20-13  shmu12: blacks ...h5 was a winning move not a drawing one ...so it proves! ivanchuk got blind for two concecutive moves and ruined all his great effort in this tournament pitty...

  tpstar: <chessgames.com> Thanks for the live broadcast. =)

Congratulations to Kramnik for a nice endgame win as Black.

This format severely punishes losing with White, but Ivanchuk can try to get even tomorrow.

<DcGentle: Ivanchuk didn't take into account <<<the airy position of his king>>>. Black checks are dangerous here!

Now Black has good winning chances.>

Each side has a queen and a rook. Black's king is <SHIELDED> by a pawn on the 2nd rank. White's king is *not* <SHIELDED> by a pawn on the 2nd rank. Black wins.

Sometimes chess is a really simple game. :-)

42...Qc6+ 43.Kh2 Rb5 44.Qd2 Qb7 45.Ra2 a3

Evaluation is -4.77

Position after 44 Qd2

The stars are lined up for black. Now comes 44...Qb7 (44...Qb6 is about as good but 44...Qd7 prevents 45 Kh3 because of 46...Rb2)

There is a nice finish with 45 Ra2 a3

You might want to take a look at this game, IMO a classic virtuoso performance on queen handling in an open position.

Kramnik vs Naiditsch, 2009

Lots of errors seem to disproportionately occur in the last move of time control. 40. f4 was a positional mistake by Ivanchuk. He gets an endgame where he has to watch out not only for a possible a-pawn advance but also for direct mating threats. Kramnik could just make safe waiting moves until Ivanchuk gets into time pressure again and make a mistake. White has to be constantly vigilant, while Black could just wait it out in safety. A dreadful endgame to defend for a human being, even if computers evaluate it as approximately equal. No human can defend a position as consistently and correctly as can computers.

Aug-21-13  deave: so sad ivanchuck lost with blunder like this.. he deserved a draw

Aug-25-13  master of defence: Isn't anything better for white 36.Qxe6 fxe6 37.Ra3?
Aug-25-13  Nerwal: <Isn't anything better for white 36.Qxe6 fxe6 37.Ra3?>

This is a difficult rook endgame for white and Ivanchuk is probably right to avoid it. It's maybe even lost, despite the pawn structure, the white pawn far advanced at e5 rather helps black (in complete contrast with Karpov vs Hort, 1979 with the same material; books are not joking about importance of rook activity).

  Natalia Pogonina: Instructive endgame. Annotations here:
http://pogonina.com/index.php?optio...
Aug-30-13  Conrad93: The commentary is a bit dull, no offense.

Comments like "this looks good" or "that looks bad" are not very instructional.

I don't feel like I gained anything from that link, Pogonina.
