Yes..Snowie's cubeless rollouts assume no Jacoby rule.

I will try to import these games into Snowie 4 and have it analysis them and
see if it thinks there are gross blunders.

There must be some enormous blunders after hitting a checker from the
backgame side since my 1296 game 2-ply rollout of the basic 31 backgame
resulted in the backgame player only winning 32% while losing a gammon over
35% for a cubeless equity of -.806.

This is to be compared with Snowie 4 where the Gammons lost are about the
same, but the backgame player won 44.7 % games and the cueless equity
is -.554 !!
