How right you are. Apologies to Albert for my imprecise checking. However, it 
is *only* 2-ply that likes the building play. 1-, 3- and 4-ply (below) like the 
slot. This could make for an interesting rollout, if 0.14 is mis-playing the 
opening roll at 2-ply.

    1. Cubeful 4-ply    24/22 13/8                   Eq.:  +0.044
       0.511 0.138 0.005 - 0.489 0.130 0.004
        4-ply cubeful
    2. Cubeful 4-ply    13/11 13/8                   Eq.:  +0.039 ( -0.005)
       0.508 0.152 0.007 - 0.492 0.140 0.005
        4-ply cubeful
    3. Cubeful 3-ply    13/8 6/4                     Eq.:  -0.078 ( -0.121)
       0.479 0.134 0.005 - 0.521 0.144 0.007
        3-ply cubeful [grandmaster]
