I think this has not been done because it is occasionally possible for the best 
play to vary if you look ahead to cube actions.

I don't know how often this comes up in actual play, and I agree that it 
consumes a lot of time for little reward.

These errors are likely to be small and, in rollouts, have very little effect 
on the overall outcome, so I think it makes sense to truncate at 0-ply during 

For head to head play, I think you would generally want to get the most 
accurate play possible. If you are prepared to play 2-ply for the rest of the 
game, I expect most people would want 2-ply at this stage.

Just my $0.02.
