Reading this threw me off on a funny tangent, because in my mind I automatically
added "until it makes no difference", meaning that if a possible path to victory
or draw exists from a certain position, it will be found. So if a 70-ply deep
engine could find all the right moves, then a 75-ply deep engine would make no
difference.
Anyhow, I then wondered whether the phenomenon of diminishing returns wasn't in
fact the ultimate sign that perfect chess is ultimately a draw. After all, if
chess was ultimately a big 1-0 then greater depth and precision (drawing closer
to this perfect win) should lead to more wins and losses and not less, no?
