I realize that. That is why I added the extra restrictions. The question I was
getting at is, will a full-width search be more accurate than one that used
forward pruning, and potentially threw away some lines, when both searches are
done to the same depth. I realize that in practice the one with (good) forward
pruning will play better most of the time.

No way to know all of the time. It's possible that the 10-ply search could
include extra lines that the 12-ply null move search pruned. Not very likely,
but possible.
