Is this constraint correct? It means that O plays at * and then can
defend if it gets another move in row, i.e. * is a threat to defend
its stone. I haven't looked at the referenced position, but it seems
at least inconsistent with the comment to the pattern. Actually it's
meaningless since there's an automatic safe move check unless the
pattern is s classified.

Underscore no good, the horizontal edge markers should be dashes.

This doesn't look much like a corner and actually rather weird with
all the wildcards. Is this as intended?
