| May-10-08 | | messachess: Chepa didn't throw this, I don't think. It's clearly an incredibly sharp line--if it is a line. Is this sac. at 22. in the literature? (Was it a blunder?) |

| May-11-08 | | guybrush: <Why not 26.Bf6 forking black queen and rook?> I guess you mean 28. Bf6. But recovering the exchange just leaves white a pawn down and closer to end game. Perhaps Cheparinov thought he had more attacking chances. However, 28. Bf6 forces 28..Qf8 (otherwise 29. Qh4 and black is in trouble) But, 28. Bf6 Qf8 29. Qd4 and white looks equal if not slightly better. Perhaps better players could clarify. |

| | Hesam7: <acirce: and the only question would be if Black can save the pawn-down endgame.> Yeah I am not really sure that ending is winning for White. How about 23.Nf3 Qd6 (forced) 24.fxg6 fxg6 25.Nxg5 Bxg5 <26.Bxg5> Rd7 (forced) 27.Be3 Nb7 (forced) 28.Bd4:

| May-12-08 | | minasina: Rybka analysis, some critical points and variations http://chessok.com/broadcast/live.p... Note: There ChessOK's Rybka suggest < 23. Bf4 +0.33 >, no depth, no variation line for that available. (See <acirce>'s first post here.) |

| | Hesam7: <minasina> I am betting that is a low depth run after the game was played. I saw the line <acirce> mentions during the live broadcast. |
|
| May-12-08 | | minasina: <Hesam7>, yes, I saw it too, see: M-Tel Masters (2008) there <23. Nf3> gives higher evaluation with lower depth: <+0.91|d17> but <+0.81|d19>. See also M-Tel Masters (2008) and M-Tel Masters (2008) (These all are on the page #27; my 1st, 3rd, and 4th posts.) |
