Kanchan is considered to be a "bad wait", because it can only wait for a maximum of 4 tiles. Thus, they are worse for [[tile efficiency|hand development]]. Like the other bad waits, kanchan can be used to [[Suji#Offense|suji trap]] opponents. | |||
In general, ''inner'' kanchans > ''outer'' kanchans > [[penchan]]s when it comes to [[tile efficiency]]. See below for details. | |||

A '''ryankan''' ("double closed wait") is an extended form of a kanchan, only available before reaching tenpai. A ryankan shape is composed of three tiles that are each 2 apart, such as: | A '''ryankan''' ("double closed wait") is an extended form of a kanchan, only available before reaching tenpai.

You end up with a bad wait, but with one significant advantage - a ryankan always forms a [[Suji#Offense|suji trap]]. Here, if you discarded the 6s, you would wait on the suji 3s, thus making it more likely for others to deal in. This is why a suji of the [[riichi]] declaration tile is considered more dangerous. | ||

An inner kanchan can be upgraded by twice the amount of tiles, so inner kanchans are overall stronger. Note that an inner kanchan waits on a middle tile. | An inner kanchan can be upgraded by twice the amount of tiles, so inner kanchans are overall stronger. Note that an inner kanchan waits on a middle tile. As middle tiles are harder to win with, an inner kanchan is worse to keep at [[tenpai]] than an outer one. | ||
