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
--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



;owl_goal_dragon(a) && lib(B) == 2
