Ippatsu: Difference between revisions

In order for ippatsu to be counted, the hand must win before the hand in riichi discards its next tile.  Furthermore, no interuption to the turn must occur.  [[Naki|Tile calls]] may immediately end the chance for ippatsu any time before the riichi declarer draws the next tile.  This includes any calls for [[kan]], except for a robbed kan ([[chankan]]).  In [[sanma]], the call for [[kita]] also interrupts and thus deny ippatsu.  Even if the hand wins before the next tile draw, ippatsu does not count if a tile call was made previously.  Thus, players may actually use the option to make tile calls to deliberately deny a player that chance for ippatsu.
