Approach Move
    Keywords: Tactics, Go term

[Diagram]
Approach moves make a difference

Although you can easily count apparent external liberties, sometimes it is necessary to play on more points than just the dame to capture a group.

Here we have a No eye Versus No eye Capturing Race. Black has two outside liberties marked a. White has one outside liberty at b but Black has an approach move c to make in order to capture White. So we can count c as another outside liberty. There is only one inside liberty: White wins even if Black has sente.

Note: Approach move is a general term which includes any move which reduces the liberties of an opposing stone or chain of stones. See approach ko.
