Sekinin barai

Main article: Sekinin barai

The rule of 'sekinin barai applies to daisangen in the form of yakuman pao. This occurs when a player seeking to develop this yakuman already had made open calls (pon) with two out of the three possible dragon types; and then the same player has taken the opportunity to call on the third dragon type. The player who discarded the third type then becomes liable for that play, where an seemingly obvious threat to a yakuman had become an apparent and actual threat of a yakuman.
