Question is: is that balance different for slow cpu's? And question 2 is: are
you going to play fast cpu's? That extremely hard to compete anyway. For a game
between 2 very slow processors I would think the balance would more go to less
smart, more tactical, faster, than for fast processors. Stuff it with extensions
and make a Genius. For fast processors that doesn't work.
