Ken Larsen's Backgammon - PRIME tactic     

  

Prime Continue, finish, or preserve a prime.  Even a mini-prime (three points) can work wonders to contain an opponent's rear checkers.  Sometimes it's justified to pass on a hit to make a prime.

Once you have a prime be reluctant to break it.

 

In the position shown red passes on hitting and pointing on gold to build a broken five-prime.  Hitting and pointing would be a 0.135 blunder.  Note that if red were to make his 3-point his chances for making a full six-prime would be considerably diminished, because points 9 and 3 can't be part of the same prime.  Points that are six pips apart cannot be part of the same prime.  Remember that.
