Doesn't the latest version of Popeye (which I don't have yet)
have a setting that lets one test OSPG's directly, without
the need to work around a static Black array?
The wQ has to be on b6; the problem with Qb4 is that d4 gives Her Majesty
an alternative path d1-d2-b4. Other than that your version looks good to me.
