Really, setting up a pattern matcher isn't all that hard.

Self-atari is in most of the cases very silly, yes. But also in a
situation like this
..XOO ..XOO
...XO .baXO
...XO .cdXO
...XO ..eXO

I'd say that d and e are both quite silly. The only really interesting
move is a, although b and c may occasionally be useful too. (Notice
that we're talking about combination attacks. b and c are more
interesting in the context of owl attacks.)
