Lack of Liberties (Damezumari) (secret)

88
"Shortage of liberties means an acute lack of liberties. Since stones with no liberties are captured, the phrase is used in certain situations to mean that some stone or stones will be captured, or would be captured if a certain play is made or is not made. E. g., "White cannot play atari because of a shortage of liberties," or "Black must connect because of a shortage of liberties." When a stone or stones has only one liberty, we say that it is in atari, so shortage of liberties is used when they have two or more liberties. Also, in a race to capture, the losing side may of course be said to have a shortage of liberties, but because that is a given, it is not put in those terms, as a rule. Of course, a shortage of liberties may be an aspect of a race to capture." - senseis.xmp.net/?damezumari
