  Marmot PFL: Black could easily avoid 31 Rxb7, but probably just made some very fast moves to run white out of time.

How do you figure plus over minus after 31. Rxb7? It certainly seems that Black is winning after 31.Rxb7? Rxb7 32.Bxa6 Rb3+! (but not 32...Rbc7? 33.Bxc8 Rxc8 34.a6 and White is still putting up a fight.)

Jul-17-09  kurtrichards: A 5-minute blitz game to break the tie? That only favors Nakamura.

  Landman: After move 30, one rook pair was exchanged and White played f2-f4 at some point (no other pawn moves as I recall). Near the end the piece positions were White Bb6, Bg2, Rg1, Kh2, Black Bc6, Re2, Nd2, Kg8. After Nf3+ Kh1 Nxg1, Ponomariov resigned with just seconds left.
Jul-17-09  totololo: It is a pitty that a first place in a classic should be decided on a blitz - why not rapid chess - 20min each for the game where they can still play a rather decent chess game... I like blitz by it is not fair....
Anyhow I am happy for Nakamura...

What is his next tournament?

I am not sure what position your comment refers to. The note to 30. ... h6 in the CG version of the game says, "Gamescore incomplete", and <Landman> seems to have some information regarding additional moves, so perhaps you are referring to some position after move 30.

The position after 30. ... h6 seems about even, and with regard to the move 31. Rxb7 (mentioned in the post by <chaq> and possibly played by Ponomariov), if play had continued 31. ... Rxb7 32.Bxa6 Rb3+!, then shouldn't the evaluation be at least three points IN BLACK'S FAVOR?

  Peligroso Patzer: I might add that the main point of my original comment (on Jul-16-09) was to question the assessment of the position after 31. Rxb7 (as given in the post by <chaq>). My original comment was not intended to evaluate any other position, nor was it intended to endorse blitz games as a tie-break method.

It does seem to me, however, given that a pair of blitz games was the primary tie-break method specified for this tournament, that these two games are what we have to evaluate and, in that context, Ponomariov never held any significant advantage during this game in any position resulting from playing through the gamescore available in the CG database. In particular, it certainly does not seem that 31. Rxb7 (?) would have been in White's favor (in fact, it seems to be outright losing).

Jul-20-09  chaq: sorry, when i wrote i was evaluating the game on ICC, and there were errors on they transmission.

Jul-21-09  tibone: Ponomariov fell asleep after 13...Bxc3, he thought almost 60 seconds definitely too long !!
Jul-21-09  tibone: maybe he was annoyed he was missing the opportunity Bd6, the drawback of ...c5. But thinking about the past is a very bad idea in blitz and in chess in general.
Jul-21-09  levelzx: Nakamura should probably challenge Morozevich in a blitz match to decide who is the greatest bullet-chess player of 21th Century.
