In order to play this >sacrifice you have to calculate correctly some very concrete lines. Of course. That is obvious and I never said otherwise. All I said was that black is OK if he plays cxd4 instead of Rc7. >For example 24.Bxc8 Bxe5 ( The ending after 24...Qxc8 is very difficult to play >for black) 25.Bxf5 d3 24.Qc6 d2 27.Bxd2 Nxd2 28.Rxe5 Nxb1 29.Bxb1 Qd1+ 30.Kh2 >Qxb1 31.Qd6 Kg8 32.Rxh5 Qxa2 = and the position after 25.Qxc8 Qf6 26.Qc4 Qxe5 >27.g3 is very difficult to play for black. > >Definitely not the typ of position you want to play against a computer. I agreed this is not the type of position a human wants to be in in another post. Did you read it before you shot off your mouth? >Therefore Adams Rc7 is a completely understandable decision. I agree that Adams decision was understandable. I never said otherwise. It was also a mistake, that's all; an understandable mistake. I have always agreed that by this point Adams was in the type of position that is hard for a human to play. That does not mean he made mistakes earlier. It is easier for white to create open, messy positions that are hard for a human to play than it is for black to prevent it, so just because it happens does not mean Adams made mistakes prior to getting into such a position. Hyrda won because Hydra played well, not because Adams "blundered" or made "outright stupid" choices or "GM Adams missed this move". I think it is disrespectful to GM Adams when people say such things, especially since Adams _didn't_ blunder. -Robin >Michael > > >> >>>But then the next few moves were mostly >>>bad by black, turning this into a debacle.
