Dual ladder breaker
Keywords: Tesuji, Tactics, Problem
A dual ladder breaker or double ladder breaker is a move which breaks two ladders at a time.
Examples can be found in difficult TsumeGo-probles such as Igo-Hatsuyoron #6?, or actual, famous historic games (e.g., see the first recorded dual ladder breaker), not to be forgotten the variations from Joseki-variants (e.g., 2-4, two-high-kakari, outside-attachment...)
