Backgammon - LINKX tactic
Destroy linkage between
opponent’s rear and forward checkers … widen the gap between them.
In the position shown red passes on hitting gold's blot on 21 and
focuses on the more important blot on 7.
Removing it will prevent gold from establishing a forward
anchor … thus destroying gold's attempt at linkage.
Hitting the blot on 21 would be a blunder, 0.209.
