Backgammon Lingo: Home Board and Closed Board

The terms "home board" and "closed board" in backgammon lingo do not refer to the entire playing area of the game. Generally, these terms pertain to a specific quadrant on the backgammon board. So what specific quadrant do they correspond to and what makes a home board distinct from a closed board?

The home board is the quadrant on the backgammon board where players must bear in their entire checkers to commence the bear off process. This area is also called the "home quadrant" in backgammon lingo where a player's ace-point to six-point is located.

If players have decided to move pieces clockwise, their respective home boards are situated on their lower left quadrant. But it gets reassigned to the opposite lower right quadrant if players have selected to advance counterclockwise in stead.

As mentioned above, a player's home board is where all their pieces must be situated as a prerequisite to bearing off. But it is also important to note the importance of the opposing player's home quadrant because that's where one must reenter their barred pieces as a means to restart that checker's journey home.

A closed board, on the other hand, applies to a home board with an additional qualification. That qualification states that it must be primed. A prime is an ultimate blockade wherein six successive points have been made that confines an enemy piece behind it. So a player who has managed to make all six points on their home quadrant is said to have a closed board.

A primed home board is fittingly called a closed board because of its superior advantage of "closing out" an opposing piece that has been barred behind it. So unless a point has been opened, there's no chance that an opposing barred checker can reenter to restart its journey. What's more, a closed board almost always ensures a gammon (double game) win or backgammon (triple game) win in most cases during a match.

In backgammon lingo, a player's home board (a.k.a. home quadrant) is where all their pieces must be before they can start taking them off the board. In turn, the opposing player's home board is where one's barred piece must reenter to restart its travel across the backgammon board. So, if a player has managed to make all six points or has primed their home quadrant, it then appropriately earns the distinction of being called a closed board in backgammon lingo.
