Fans of pseudocubeless numbers...

I'd like a rollout result to display the quasicubeless equity (as Gnubg does)

Are you referring to the piece of output that shows -0,032 in the following example? If so, are you sure it is what you think it is (here's what one Gnubg developer thinks it is)? Do you find it puzzling that a cubeless rollout gives a similar breakdown, but a quite different equity? Does your version of Gnubg give similar results? Admittedly I have not updated mine for years.

The score (after 0 games) is: gnubg 2, stiebler 0 (match to 5 points)

Move number 3: stiebler to play 32
