This is just for your information. The cubeless equity 3-ply is +0.470.

>   0.641 0.264 0.020 - 0.359 0.081 0.002
> 1. No double            +0.497

> 3. Double, take         +0.326  ( -0.170)

The "No double" and "Double, take" are *always* calculated as cubeful
equities. In fact, gnubg can't anything else! If you toggle the cubeful
flag for cube decisions the difference is that the best move on the
intermediate plies is selected cubeless not cubeful. However, gnubg
still calculates cubeful equities.

For chequer play decisions the cubeful flag means that both the
resulting equity as well as the move selection on intermediate plies are
cubeful (or cubeless).
