Why can't it be matched on the edge?  It looks fine to me.

The constraints could probably use a little work.  Checking the tactical
stability of all the relevant strings is probably correct, but it should
be done for both X strings (not just one like in A719), and should be done
after the move is played (eg, an oplay_attack() constraint).
