This type of thing (snapback to produce nakade) is
of course quite uncommon. It still should be possible
to filter snapbacks. It is certainly easy to characterize
them.

However I admit that the best method of filtering them is a little
unclear due to this type of example. One way would be not to
accept a snapback move unless it is the only owl attack
move for some dragon. Or maybe your method of giving a
negative shape value is simpler and better.

In any case I've been seeing snapback captures in
real games and I think something should be done.
