Due to a small mistake I made during setup, Ruffian used it's own book in
addition to the Kurzbuch (not intended in this case), for up to 5 more opening
moves. But I think it was not decisive (Ruffian won games where it's book had no
more moves, and lost games where 5 moves came from the R. book). In Ruffian -
Chess Tiger, Black lost on time (which is very seldom known from Tiger) in a
good position. Otherwise, these two would probably have switched their rankings
in the final table.
In addition to the 6-ply CTG book, the engines found an average of 3,6 opening
moves which have already occured in human master's chess. The maximum was 13
calculated GM moves like in the game Robert Byrne - Wexler 1964, played by
Junior 5 against Shredder 5.32:
