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.

Subtle point about approach moves

(Sebastian:) I just noticed that this definition is completely different from the definition of approach. Thiss is really an unfortunate distinction, because an approach that is not an approach move is still a move. We distinguish the part of the term that both have in common! Is there really no better way to distinguish the two?
