Chuuren poutou: Difference between revisions

The key to this yakuman is the possession of ankou of both 1's and 9's of one suit.  If two of either group of tiles are not available, then any attempt at this yakuman is no longer possible.  Of course, that is in addition to the collection of a string consisting of 2-8 tiles of the same suit.  Since this hand uses a single suit, it overlaps [[chinitsu]] during development. In fact, many tenpai formations may result in chinitsu, rather than the yakuman.  This is due to the ability of chinitsu to form some [[Machi|complicated waits]].
