Hmm, seems I was thinking of the wrong pattern.  Anyway, the turn or
extension to the 2,2 point is worth 2.33 by miai counting in the basic
case (maybe more if there are relevant weaknesses).

See http://senseis.xmp.net/?MiaiValuesList200AndMore

Counting it 3 points of territory is probably a bit simplistic, but
seemed conservative enough to not be problematic.
