Your point would be?  Computers have been playing in human tournaments since
the early 1960's.  I played in many myself from 1970 through 1988 or so. I
was _never_ required to provide program output.  I was _never_ required to
do anything other than show up and operate the program.

I don't see how this match was any different.  It was _just_ a chess match
between two players, one of whom was a computer.

Here is what happened.  He asked.  At the press conference. Someone said
OK (he asked for output for two moves in game 2).  They decided that this
would take some time to get and they were not sure they wanted to give it
to him.  However, within the week, Ken Thompson had the printouts in his
posession, for the two moves in question.  The output was published in the
NY times, in fact.

I don't think it appropriate to give him _anything_ during the match.  Why
does he get to see inside DB's head, when DB can't see inside his?

Not being a psychiatrist, I won't go there.  I don't know what went thru his
mind.  However, the last time he lost a game vs a human, did he start accusing
the human of having outside help?  Did he demand that the human explain exactly
why he made a couple of moves, to prove that the player knew what was going on,
rather than getting info from outside the playing area?

Seems like he was trying some mind games of his own, in fact...

DB beat Kasparov in 6 games.  He prepared poorly.  He got terrible advice about
how to prepare.  It blew up in his face.  He found himself in a war with a
machine that was tactically unlike anything he had ever seen.  I think the
pressure got to him.  All matches have pressure it seems.  Some real, some
imagined, some self-conjured up.
