Riichi: Difference between revisions

A player may actually declare riichi with a [[Tenpai|noten hand]].  This is a '''noten riichi''' {{kana|ノ聴立直}}, which is highly not advisable.  Of course, computer based play is usually programmed to prevent players from making such a riichi declaration.  If and when the hand results in [[ryuukyoku]], then it is required of the player to reveal the hand to show tenpai.  The noten riichi would naturally show noten; and it is subject to [[chombo]].  Likewise, chombo is applied if a win is called, as the hand's winning status would be verified only to reveal an invalid hand.  Players may escape this dubious position, when another player wins the hand or has committed a chombo penalty.  An [[abortive draw]] may also prevent the chombo penalty, except suucha riichi.

'''Double riichi''' {{kana|ダブル立直}} is a special case for riichi.  Here, the player declares riichi on the first turn before one's own discard. No tile call may have interrupted the turn order before the declaration, where applicable.  For the [[dealer]], double riichi can never be interrupted.  As the name implies, this yaku is worth 2 han instead of 1 han, as a bonus for the initial timing.  With the added han value, a call for double riichi has a huge advantage over the other players in conjunction with the immediate speed and value compared to conventional riichi calls.
