I dont know about you but I found (Cerebellum book April 16) better than this new release (Cerebellum book May 23).
"Because of the long time between this and the last release, and the calculation with stronger SF engines,
the library may play much different or there may be some unexpected behaviour.
If problems occur with that release (for example three fold repetition or fast draws with white),
I will correct this in the next release."
So I will wait!!!
