Parallel ladders

Note: None of the ladder-related terms on this page are established Go terms.

Parallel ladders may mean any of the following:

• Alternative ladders.
• Intertwined ladders.
• A special kind of spiral ladder where one ladder is run to the end, and after a capture and a squeeze another ladder runs parallel to the first ladder so that the "surrounding" stones between the two ladders alternate between one and two liberties. See Example 3 of turnaround ladder.
