The term covers a very simple idea: in backgammon booby point is the opponent player’s bar point. Actually we are not talking about a single bar point because there are two of them, and these bar points would be the seven-point and the eighteen-point, because these are next to the bar. It is known that escaping with both men from the booby point is very difficult, so you should think about the booby point as a liability, especially when the opponent player has better timing.
