Tochuu ryuukyoku: Difference between revisions

'''Tochuu ryuukoku''' {{kana|途中流局}} is more commonly known as an '''abortive draw'''.  Specific game situations end a [[kyoku]] (hand session) without any player declaring a win or [[Ryuukyoku|drawing all tiles]] from the wall.  With the exception of kyuushuu kyuuhai, all cases of tochuu ryuukoku are mandatory, when they occur.

'''Kyuushuu kyuuhai''' {{kana|九種九牌}}, literally means 9 (kyuu) kinds (shuu) of honor or terminal (kyuu) tiles (hai). If a player's 14-tile hand after his initial draw is composed of 9 different honor or terminal tiles, the player may announce this and reveal his hand to abort the deal. This option is only available if no tile call has interrupted the initial turn earlier. Instead of calling kyuushuu kyuuhai, a player may play the hand normally, maybe aiming for [[kokushi musou]].  This is the only case where the call for tochuu ryuukoku is optional.

As required with riichi declarations, all players must reveal their [[tenpai]] hands. Players without tenpai hands are punished with a [[chombo]] for declaring riichi while noten. After committing a chombo, the hand must be repeated, but no honba is added and all riichi declarers get one riichi stick back.
