Approach Move
   

[Diagram]
Diag.: Approach moves make a difference

Although you can easily count external liberties, sometimes it is necessary to play on more than just the liberties 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.
