Outside Liberties
The liberties of a group that is involved in a capturing race, which that group doesn't share with the enemy group involved in that capturing race. Outside liberties are also known, in English, as external liberties. In the diagram below, the points marked with a circle are outside liberties of the surrounded black stones; the points marked with a square are outside liberties of the surrounded white stones.

Richard Hunter I regard liberties in an eye as not being outside liberties. I use the term exclusive liberties for ones that are not shared with the enemy group.
