[gnugo-devel] komoku josekis, continued

[Evan Berggren Daniel]

I've played through more openings against GNU Go with my komoku additions,
and found a few small fixes.  This patch adds a few variations, marks some
bad responses, and also how gnugo should answer them.

Any comments or suggestions would be appreciated.

Thanks

Evan Daniel
