Talk:Daburu riichi
impossible for South
"No tile call may have interrupted the turn order before the declaration, where applicable. For the dealer and the player to the right (South), this case would be impossible."
In what sense this is impossible for South? Clearly East can deal something which will be stolen right away, and the possibility of daburu riichi for South disappears. Tsumo (talk) 23:58, 23 February 2014 (UTC)
- A small case, that I had failed to consider. So, you are correct on that. KyuuAA (Talk:キュウ) 11:32, 24 February 2014 (UTC)

Tile Calls
Previous versions of the page claim that double riichi is invalid if a "tile call [would] interrupt the turn order before" before the riichi declaration. This would imply that chi calls would never interrupt double riichi, and pon calls to a player's kamicha would also not interrupt the yaku. However:
- Tenhou and chiihou state that chiihou can "be denied by any tile call made prior to the first draw", which implies that chi disrupts the yakuman. Also, ippatsu is denied if chi is called. From common sense, if chi disrupts chiihou and ippatsu, it would also disrupt double riichi.
- Tenhou rules and Majsoul#Rules both state that calling kita interrupts double riichi. Kita does not interrupt turn order, so this violates the above definition.
- In addition to the online clients, WRC 2022 rules states that kan (which does not affect turn order) disrupts the yaku.
I think this amount of proof is more than enough to show that, in many rulesets, chi/own kan/kita will disrupt doublerii. Maybe there's some house rules i'm missing here.
