The Rule of 4
When you hold only your midpoint and 8pt in the outer board, and your opponent is playing a holding game with a single anchor on either the 5pt or the bar point, it is very hard to lose your market. Just about the only sure market losers occur when you are able to clear the midpoint by rolling doublets.
That being the case, it is not necessary to double until you get down to 4 checkers or less on the midpoint.
