An extension? They're Q-nodes, and I don't "extend" in Q-search.

That's just as good (or better). But I don't think it can be measured at all if
I do this or that. And the counts should be the same anyway. It's conceptually
simpler, though, which is why I might change how I do it.
It's still a mystery why I get 97% qNodes in this position.
