Re: [gnugo-devel] Patch: Strategic effect for strategic attacks and defenses

[Arend Bayer]

I made another small experiment, using Dan's new code in the simplest
possible way. The result is pretty mixed, and analyzing it might give
useful hints for improving both approaches to measuring escape potential.

(This uses only half of the potential of the new code, i.e. doesn't use
whether a defending move breaks out of the surroundedness, etc.)
