OK, you've all convinced me :-)

A few related questions:

What if the user selects cubeless rollout? Which gammon price should be
used for match play and money play, respectively?

What gammon price should be used for cubeless chequerplay for match and
money play, respectively?

A related question: gnubg also shows a cubeless equity for match play.
Should this cubeless equity be

* cubeless normalised equity 
* or cubeless money equity?
