... of course it's still possible that you played this line before with M-Chess,
it won (e.g. against Crafty on ICC or something like this) and extended its
book. After it lost at 40/120 against Rebel, it now deleted the refuted line
again ... Everything's possible, if you take the extremely ambitious learning of
M-Chess into account ... But I still would feel more comfortable with the result
if we knew exactly what was going on. Maybe it helps if you just watch the next
game closely after the first moves out of book to ensure that everything is ok -
but then, the fact that M-Chess does permanent brain while it's still in book
(unlike other programs) would blur any conclusions based on response time
observations if the opponent is sooner out of book than M-Chess - it might
respond instantly up to move 60 although it left book after e.g. move 15 if it
correctly predicts all opponent's moves ...

What a mess.
