Re: [gnugo-devel] Extremely bad mistake

[SP LEE]

Maybe I was wrong, but I found gnugo couldn't find A11 as a defense point for 
C19 to make seki. This in turn made C19 as defenseless and gnugo just ignore 
the attack point A16.

Then I come to the question, does gnugo only look at liberties of its own group 
for attack/defense? Of course my question seems to be too fundamental, but I 
really like to see this problem solved.
