Universal name
I have to wonder if there is a universal name covering all three. Otherwise, daisharin is arbitrarily selected as the article title. Out of the three, it is the easiest one to remember. KyuuAA (Talk:キュウ) 06:40, 17 July 2015 (UTC)
Daisharin is the one used to refer to the three as a group. Jp.wiki seems to imply that they're an uncommon variation. Coppro (talk) 20:12, 18 October 2015 (UTC)
Notes of guaranteed pinfu
When the hand is completed, the pair candidates will always come from 2/5/8. For the cases waiting on 3/4/6/7, simply choose the pair close to the actual wait, the hand can always be interpreted as ryanmen.
E.g. 2233445567788 waiting on 6: 223344 + 55 + 67788.
