Here I am considering the important detail that white is a >computer, black is a human. In that regard, black is _not_ equal up to move 23. By that logic Adams was already much worse after 1.e4 no matter what he did. Let's face it, Hydra is stronger. Adams will probably be under presure in every game where he has the black pieces. > In fact, I don't believe black is anywhere near equal. He is equal unless you use your "considering the important detail that white is a computer" logic. >He isn't lost, but he is far from equal and is at best fighting for a draw. >But in an open position. >And he just has no chance in that kind of position. He was under presure, yes. That is a far cry from "has no chance". >But I would take white anywhere along the way in that game, as a human playing >another human. And by the way, any move after the "knight to the rim" move >finds white better IMHO. Your opinion is wrong, unless perhaps you mean that white had a very slight advantage. That is the norm in chess, by the way. >>Adams played 23...Rc7 while 23...cxd4 looks like it holds everything nicely >>together. > >Doesn't quite hold everything nicely together.

Maybe not "winning better" but >"significantly better". Try "very slightly better". Adams played well until Rc7. Hydra is very strong and kept putting the presure on and finally Adams made a mistake. -Robin
