I found a problem which gnugo 3.7.11 fails to solve; it requires
setting up a cute little snapback.
Both the problem and the solution are attached.
I tried both
--decide-semeai d1/g3 prob5.sgf -o result.sgf
and
--decide-dragon d1 prob5.sgf -o result.sgf
Any ideas on how to improve the semeai/dragon routines?
An owl defense pattern like this maybe?
Pattern D235
??XXO squeeze for some extra eyespace
oO.*x

:8,-,value(67)
??BBO
oa.*x
