OK.

I was hoping to avoid extensive trials as presumably one match doesn't do.
At least it should be a rather long one.
And then I'm no bg expert. I can say whether it takes too long for my
taste, but I can't assess GNUbg's match evaluation. So I can't really
decide when to stop reducing the search space. Maybe even static analysis
is enough. I don't know. However, from comments on this list I believe it's
safer with 2ply.

And in order to understand how this speed option works: Could you relate on
this, especially in conjunction with move filters? Are the settings for the
move filters then halved for the next ply, or so?

Please, keep us informed. I'd be interested in this discussion.
