Well, yes, in principle. If I haven't been in book for a couple of moves (5
moves at the moment, I think), I don't probe the book anymore, though. With my
hardware (and the hardware I have access to), the binary search scheme works
fine on the ~100MB books I've used so far. I know it can easily be improved, but
I see no reason to do it until the need arise.
