Ken Larsen's Backgammon - LINK tactic     

  

Linkage close or preserve a gap between rear and forward checkers.  This also entails not enlarging the gap between your rear and forward checkers for example, by not abandoning your midpoint.

 

In the position shown red doesn't have enough timing to support a backgame, so he must play 24/20 to improve the linkage between his rear and forward checkers.  The second best move, 13/9, 6/3, attempts to fall into a backgame and is 0.048 worse.
