A 70% win expectancy is around 140 ELO, so I guess you are suggesting that this
is how much stronger Rebel would be if it could ponder every move correctly.
But this seems like a different discussion - I don't quite see how it relates to
the question I asked Bob.

The point I was trying to make is that it shouldn't be that hard to modify
Crafty's time management code to handle the PB=OFF scenario.  Bob says it would
take a lot of tuning to get this working well in Crafty, which seems odd to me,
but I will take his word for it.

Perhaps it is just too late - am I missing the point of your post?
