Yes
I now look at the games(something that I did not do in the previous reply) and I
find even a game when the players were out of book in move 101.
Usually the result was decided by book and not by the engines so it seems to be
a clear way not to test the strength of the engines.
For some reason it seems that the full game of the GM's was part of the book and
when both players use that book it is clear that in most games the book decides
the game.
I do not understand the reason to post games when it seems that the people who
post them even did not look at the games(otherwise they could pay attention to
the problem)
In the game that I post it is an easy draw after 100 moves and I do not
understand the reason that Comet played 113...Nf3
Seem to be a bug in Comet.
Most of the games were decided by book and the few games that were decided by
bugs or when the GM's agree to a draw too early are only a minority so it is
clear that the result is meaningless.
