Chankan: Difference between revisions

If the rules allow, a special case for [[kokushi musou]] exists.  This involves a kokushi tenpai hand, where the final tile may be completed with an opponent calling [[kan]] with a closed kan using all four of that particular winning tile.  Thus, ron may be declared in that instance, involing the special chankan rule.  This is the only case where a tile may be taken from an closed kan.  However, this particular rule may be [[Yaku_variations#Kokushi_and_chankan|subject to variation]], which may or may not allow the play to occur.
