 ==Strategy==
-Kanchan is similar to [[penchan]], by which it waits on 4 tiles maximum for a single numbered tile type for completion.  Likewise, this pattern can hide against [[suji]].  However, kanchan is more versatile as it is able to use a greater range of tile types.
+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]]. However, kanchans are considered better than [[penchan]]. Like the other bad waits, kanchan can be used to "[[Suji#Offense|suji trap]]" opponents.
+===Kanchan vs Penchan===
+Kanchans are stronger than penchans because kanchans are easier to upgrade.
+*A {{#mjt:24p}} kanchan can be upgraded by drawing {{#mjt:5p}}, turning it into a {{#mjt:45p}} (two-sided) [[ryanmen]].
+*A {{#mjt:12p}} penchan cannot be upgraded to ryanmen on its own. It must first draw a {{#mjt:4p}}, turning it into a {{#mjt:24p}} kanchan, then draw the {{#mjt:5p}} to get a ryanmen.
+As a kanchan requires 1 tile to be upgraded to a ryanmen, but a penchan requires 2 tiles, the kanchan is superior to keep. However, when you reach [[tenpai]], then kanchan and penchan are effectively identical.
