FIBS Board backgammon forum

we hit and i moved the 52
roman danced..
do we recube?

I missed the vote, but I'll comment anyway.  Roman has the better board and is ahead in the race.  But he's on the bar with nine dancing numbers and has an exposed blot. If we hit the blot (12 shakes) and he fails to anchor (only three shakes anchor with two on the bar) it's definitely a market loser.  Or if he just dances, or if we make a fourth homeboard point.  So I  think we have the requisite market losers to cube, the question is whether we've already lost our market.  I think the fact that he leads in the race and has the better board plus an anchor on the bar point gives him enough to take.  And if it's a take, it's not TG.   I'm not convinced it's a take, so ship it according to Kit's law.

Rollout forthcoming.

A fairly straightforward R/T.  Well done on both sides.
