If you play 10 minutes per game then it is better to use less than 16MB for
Junior5.
I am sure that Junior5 cannot fill 16MB hash tables in 10/0 games.
8 MB is better and I believe that even 4MB is enough for this time control on
pentium200MMX.
Junior5 clear the hash tables before every move and it takes time.
