Link Removal

Why remove a link?

The most common reason for removing a link or links is to avoid a draw.

Link removal example

White to move here should play i5, as indicated, removing the G5/H7 link (or, using Alan's notation, the G'6 link) and then double linking from G6 to H3. White could optionally play H4 instead of i5, but either way, the G'6 link should be removed so that white can have a contiguous chain of links connecting both border rows.
