An opening 6-1 makes the bar-point: 13/7 8/7. The 7-point starts a three-point prime (6, 7, 8) that can trap your opponent’s back checkers before the game is a dozen moves old. Unlike inner-board points, the bar-point also works as a blocking point for a priming game, which is why every bot ranks 13/7 8/7 clearly first. The main strategic follow-up: try to extend the prime with the 5-point or 9-point, and do not rush your back checkers out while the block is doing its work.
