Ähm, I don't care much if my name is not written correctly, but this spelling is
totally wrong. :-)

1) Note that the first move calculated by Junior in this game (no. 5) is move
#17. Both programs played from the book up to then. So at move #22 there is some
moves hash inside.
2) I used 128MB hash, which hash size did you try?
3) Not Junior took 848 seconds, but Tiger took 848 sec for 21...Kf8. Sure,
Junior moved immediately after this 848sec but Juniors move #21 was also
immediately so I'd say all this hash/permanent brain may cause the difference.
