Edge of a prime: The open point directly in front of a prime. When trying to escape a checker from a blockade it is easiest to do from the edge of the prime.

a gammon or a backgammon. When a player has one checker on the ace point facing the opponents last three checkers on the two point, it is better not to eject because you are guaranteed a shot and possibly a double shot on your next turn as long as your opponent does not roll doubles higher than double 1's.

Extras : 1. A rule sometimes used in Chouettes when not all of the players offered a double by the box choose to accept it. Any player who refused the double may offer that cube to a player who took the double originally offered by the box as a side bet on the outcome of the game. The extra cube is offered at the same level as the original and payment would be at half the value of the cube. Another optional rule regarding extras is to make the acceptance of extra cubes mandatory.
The practice of offering extras tends to punish bad cube takes and keep everyone involved in the game. 2. Mandatory extras are sometimes used in money play when the doubler is allowed to give an extra cube at the same level if the original double is taken. The doubler pays the receiver half of the cubes value and the receiver may then use both cubes to use together or separately for future doubles. The use of mandatory extras is for players who like a little more action (aspect of gambling) in backgammon.
