So, when it comes to [[machi]] (wait patterns), only three basic types can be used for chankan: [[penchan]], [[kanchan]], and [[ryanmen]]. Some patterns that utilize any of these three may also apply. This is simply due to the number of tiles remaining (just one), for every minkou. So, tile patterns involving [[shanpon]] and [[tanki]] are impossible for chankan, as they each possess tiles necessary for kan calls. | So, when it comes to [[machi]] (wait patterns), only three basic types can be used for chankan: [[penchan]], [[kanchan]], and [[ryanmen]].
