D1383 shouldn't be matching because of the constraint.  D301 appears to be
the culprit.  Looking atthe pattern, it appears that the only way the
stone could be disconnected is a shortage of liberties.  Therefore, adding
a constraint like !oplay_attack(*,B) with B being the two stones on the
left would seem workable.  Adding a connection reading constraint or a b
classification to the pattern would work, but this constraint should be
faster to check than either of those.
