The running game describes a strategy of moving as quickly as possible around the board, and is most successful when a player is already ahead in the race.A holding game is a strategy wherein a player keeps a point high in his opponent's board or on his opponent's bar point, as the game progresses. The player may gain an advantage by hitting an opponent's blot from the held point, or by rolling large doubles that allow the player to advance both checkers and begin a running game.The priming game involves building a wall of checkers, called a prime, ideally covering six consecutive points. This obstructs opposing checkers that are behind the blockade. The prime is usually built somewhere between the 11-point and the 2-point, and then shuffled into the home board as the game progresses.Backgammon Galore, "Backgammon FAQ", What is a prime?.
