You may find that a good static exchange evaluator will work even better,
because you can prune many losing captures out entirely, and for those captures
you can't prune, your sort order is a little better.

It's hard to write it well, and your node per second will go down since you do
work to avoid nodes without getting to count them, but you'll see stuff faster,
I predict.
