Kan during riichi | You are able to declare a closed [[kan]] after a riichi. When this is legal will depend on the ruleset; improper calls may be subject to [[chombo]]. See [[Kan#Kan during riichi|Kan during riichi]] for more details. Even if the kan is legal, you may or may not want to declare one. | ||

'''Open riichi''' {{kana|オープン立直}} is an [[optional yaku]] which is a modified version of riichi. The mechanics are identical to a normal riichi, except that you must reveal either your entire hand or its tile [[wait]]s. In exchange, an open riichi is worth 1 extra han. Open riichi makes it trivial for other players to defend against your hand, so in general, the intent is to win by self-draw. | '''Open riichi''' {{kana|オープン立直}} is an [[optional yaku]] which is a modified version of riichi.

As a further optional rule, yakuman may be awarded if any player intentionally [[ron|plays into]] the open riichi. If a player unintentionally deals in, i.e. if a riichi player deals into an open riichi, the yakuman is not scored. | As a further optional rule, yakuman may be awarded if any player intentionally [[ron|plays into]] the open riichi.

Once again, the prospect for [[rinshan kaihou]] to work with riichi is dependent on the legality of the [[Riichi#Kan_during_riichi|kan call during riichi]]. With computer interfaces, this rule may be enforced by disabling a player's ability to call the kan during this situation. However, with actual tiles, a player must be aware of this legality. Otherwise, chombo may be enforced instead. | Once again, the prospect for [[rinshan kaihou]] to work with riichi is dependent on the legality of the [[Riichi#Kan_during_riichi|kan call during riichi]].
