Daburu riichi: Difference between revisions

Double riichi's greatest advantage, aside from its speed, is the lack of information regarding [[safe tiles]] at the beginning of the hand.  Initially, every tile is considered to be dangerous, as no to few discarded tiles show any indication of safe tiles.   

However, this advantage can be worn away through the [[furiten]] rule. While a player in riichi, every tile not claimed for a win is considered safe against the riichi caller. If a winning tile does not come soon enough, the other players may themselves reach tenpai. If affordable, a player may employ [[sashikomi]], in the hope of dealing into a cheaper hand.

For more unusual situations, the threat of a double riichi can be averted by ending the hand via [[Tochuu ryuukyoku|abortive draw]]. [[Kyuushu kyuuhai]] can immediately end the hand before the declarer can claim tsumo.  An even more unusual possibility can end with suufon renta.  Eventual means can be provided by [[sanchahou]], [[suu kaikan]], or even a risky [[suucha riichi]].
