In chess, we have a root position, and we search to a terminal position where we apply an eval and then back up a score. I don't see anything that would suggest that it is better (or worse) to extend near the root or near the tips. Except that extending near the tips causes the tree to grow quicker. But nothing suggests that you can't get from the root position to the right tip position by extending early, vs only by extending late. The issue is extending _right_. Which means that program A might do better with one approach, while B might do better with the other. The chess program is the sum of its parts. And all this comparing with DB is nonsense...
