Ken Larsen's Backgammon - JOKER tactic
If you've got a big lead and are cruising to victory, watch out for "joker rolls" that could trip you up. Examples: 1.) Protect yourself against 6-6 when bearing in. 2.) If the only way that your opponent can hurt you is to throw a 5-5, stay away from a point that can be hit by that 5-5.
