-Alternatively, this yaku may be referred to as "robbing a kan".  [[Tenpai]] for chankan must involve a hand, in which one of the [[machi|waiting tiles]] has been called as [[naki|pon]] by another player.  Any tenpai hand works for chankan, as long as the waiting tile(s) have been called for [[naki|pon]] earlier, and then the player calls for an added kan.  Naturally, waits involving [[jihai|honor tiles]] do not work in this situation.
+Alternatively, this yaku may be referred to as "robbing a kan".  [[Tenpai]] for chankan must involve a hand, in which one of the [[machi|waiting tiles]] has been called as [[naki|pon]] by another player.  Any tenpai hand works for chankan, even "yakuless" hands.  As long as the waiting tile has been called for [[naki|pon]] earlier and then the player calls for an added kan, this creates a time for a player to claim the added tile for a win.  Naturally, waits involving [[jihai|honor tiles]] do not work in this situation.
 While the call for kan reveals additional [[dora]], in the form of kan-dora, the call for chankan interrupts the process for kan.  Therefore, additional dora is not revealed.
