Heikki,

	You are right. If a program is designed to play another program, frequency
in "real world" won't be appropriate. If a program is designed to play
human, the frequency might make some sense. If a bulky-five is not in the
database and the program encounters it, calculations might find out a
solution for it. My understanding is that patterns are used to reduce
calcuations only.
	What do you use for your pattern database?
 	Thanks for your discussion.
