Open Riichi

Open Riichi (oopun riichi) is when a player who declares riichi can decide to reveal the section of his hand that he is waiting to complete.
If the player wins on a discard (Ron), it is worth a Yakuman, the only exception is when the player who discarded the tile was in riichi, because he/she had no choice.
