Wow! And still you call yourself a novice. That's style!

Of course this might be possible. Only - also that fact seems to prove my
assumption. They are simply not interested. That they are innocent is hard to
believe. Khalifman for example is using a chess database since 1991. And with
that base he always had the included chess engines! In a way your authentic
report is somehow proving my theory about aristocracy among chessplayers. In a
way playing seriously against a computer (apart from training) seems to be of
little interest. Different if you can make money just by accepting e.g.
ChessBase's proposal to play the newest version of FRITZ...

Possible. But you should not confuse GM Roman D., who has mainly left serious
chess, with the actual elite of players. For them the forced play against a
computer in their tournaments is an odd thing. Something not to be taken for
serious.

Don't take me as arrogant but the 'Hail Van Wely!' exclamations after that
trivial computergame go a bit too far. From the standpoint of serious tournament
chess this game does not make much sense. It is reminding you on the chess of
the 19th century at best...    :-)
