Woolsey said of the program that "There is no question in my mind that its positional judgment is far better than mine. This reduces the likelihood of loaded dice being used, which is the main way of cheating in face-to-face play. A particularly successful priming effort may lead to a "blitz", which is a strategy of covering the entire home board as quickly as possible while keeping one's opponent on the bar. Before the commercialization of artificial neural network programs, proposition bets on specific positions were very common among backgammon players and gamblers.

After rolling the dice, players must, if possible, move their pieces according to the number shown on each die. If a checker is hit during the bear-off process, the player must bring that checker back to his home board before continuing to bear off. To understand this post properly you need to understand the pip count and how it is used in backgammon. A roll of 6 and 6 means that the player has four sixes to use, and he may move any combination of checkers he feels appropriate to complete this requirement. Checkers can enter on unoccupied points, or on points occupied by a single opposing checker; in the latter case, the single checker is hit and placed on the bar.

Doubles had originally been recorded by placing "common parlour matches" on the bar in the centre of the board. If the opponent doesn’t want to resign, he may accept the double, and agree to continue play at double the previous stakes. For example, a player leading a 9-point match by a score of 7–5 would be very reluctant to turn the doubling cube, as their opponent could take and make a costless redouble to 4, placing the entire outcome of the match on the current game.

It was written by Hans Berliner in the late 1970s on a DEC PDP-10 as an experiment in evaluating board game positions.This is because in backgammon the roll of a double is played slightly differently from a non-double roll.
