0-ply evaluates the resulting positions quite haphazardly and there is 
only one move with 24/19 if the first eight choices. The wider filter 
gets three more and these four get the top spots at 2-ply. This is 
better but there are still a few reasonable 24/19 plays missing.

The 0-ply evaluations of the next roll position are probably rather poor 
as well since the 2-ply equities of these moves are much more dispersed 
than they should. 3-ply is better and 4-ply seems right, with all the 
plays breaking the 24 point sensibly in a 0.02 interval.
