'''Chankan''' {{kana|搶槓}} is a standard yaku.  It is dependent on the usage of [[kan]], where a player may declare ron while a player calls to upgrade a [[koutsu|minkou]] to a [[Kan#Shominkan|shominkan]].  In other words, if a player is tenpai for a tile used for an "added kan", then the player may declare a win on that tile.   
'''Chankan''' {{kana|搶槓}} is a standard yaku.  It is dependent on the usage of [[kan]], where a player may declare ron while a player calls to upgrade a [[koutsu|minkou]] (triple called via [[pon]]) to a [[Kan#Shominkan|shominkan]] (added kan).  In other words, if a player is tenpai for a tile used for that specific added kan, then the player may declare a win on that tile.   


In almost all cases, players are not allowed to call ron on an [[Kan#Ankan|ankan]] (closed kan). The notable exception involves a [[kokushi]] [[tenpai]] hand, where the last tile needed for the yakuman is called for an ankan.  However, the kokushi exception varies on the rules.  In [[Rule_variations#Kokushi_and_chankan|some rules]], it is disallowed outright.
