<Update: Looks like we're headed for a blitz playoff. Nakamura handled his business and held Kasimjanov to a quick draw. But Vallejo is defending rather horribly an exchange down after a direct attack by Ponomariov netted him a big plus. <<<(And he could have won instantly with 26.exd6! winning the black queen.)>>>>

Jul-17-09  markofthemushroom: I don't know much about tactics but "26.exd6!" looks like "26.exd6???"...let me take that back, it looks like "26.exd6:(" it looks like it hangs the white rook at E1 and the white king in the process.

  Gilmoy: No no no -- 26.exd6! properly returns the exchange for an unstoppable d-pawn and back-rank tricks:

26.exd6! Qxe1+ <might as well; Qd7 27.Re7> 27.Kh2 Qe8 <Rc1 28.Re3 Qh1+ 29.Kg3 Rg1 30.Re8+ Kh7 31.Qe4+ defends g2 and 32.d7> <or 27..Rc8? 28.Re3 Qb1 29.d7 R-any 30.Re8+> 28.Qxh6 Qf8 <g6 29.h5> 29.d7 .

Jul-17-09  stukkenjager: 26.exd6!! wins on the spot,a shame that Ponomariov missed this chance.

26.exd6 Qxe1+ 27.Kh2 Qe6 (27...d4 28.d7 Rd5 29.Qf6 g6 30.h5) (27...Qe8 28.Qf6 g6 29.Re3 Qf8 30.d7) (27...Rc1 28.Re3!!) 28.Re3 Qc8 29.Re7 Qf8 30.Qe5 1-0

Jul-17-09  markofthemushroom: Ok, Rybka 3 on a netbook config gives 26.exd6 an advantage of a rook and two pawns. If Pancho had posted his knight on E4 earlier it would have provoked a rook sac with an attack that he could had lived thru and won...I think, even if he had won it I don't think that he would have ever been the same. Chess isn't for the timid...I guess that includes most of the best that humans have to offer. "Romantics" from the 1800s have a better chance to beat the machine than current GMs and super GMs. I think that both of them discarded "winning" moves that would have caused a lot of hassle.
Jul-17-09  stukkenjager: a rook and two pawns, I was thinking in the line of two rooks and two pawns!
Jul-17-09  markofthemushroom: Hey, I have a netbook with one GB of RAM. It gave me one rook and two pawns. It called the initial pawn push by white, 14.d5 a move that left a lot to be desired. Seems that Pancho pissed the little bit of a slim advantage (1/10th of a pawn...maybe less) that he had down the toilet with ...15.h6.
Jul-17-09  markofthemushroom: The engine also said that Pancho captured the bishop with the wrong piece (the queen) and should have captured with the rook that was on the C-file. It is amazing how one of these engines could exploit the smallest thing. If a GM can't do a capture, then I sure as hell know all of us are in trouble.
Jul-17-09  Valmy: Why do you call him "Pancho"?
Jul-17-09  markofthemushroom: Pancho is the shorthand name for Francisco
Jul-17-09  Valmy: Well, in SPAIN, as far as I know, it's PACO. But it's not important.
Jul-23-09  WhiteRook48: 36 Qd6! forces the e-pawn through
