What do you mean with "pairs of positions" ? The same board setup with 
player 1 / player 2 on roll ?

Have you got any other explanation for the behavior described here :

I'm not sure anybody has done a 0ply comparison of the bots recently
mainly because nobody is using 0ply anymore, not even for rollouts.
But I won't be surprised if gnubg is still the strongest, actually I
do hope so.

However, the fact gnubg may misplay that badly the cube decisions as the
above may make users doubt about its real strength, e.g. would you trust
a cubeful rollout where the position above can be reached ?
