'''Suu ankou''' (四暗刻) is one of the standard [[List_of_yaku#Yakuman|yakuman]] hands. This hand consists of four concealed [[Mentsu#Ankou|triplets]] and a pair, i.e. none of the triplets must have been claimed from other players' discards.  If the hand is on a [[shanpon]] wait, the winning tile must be a tsumo and not as a discard of another player.  A win by discard may render the fourth triplet as an "open" triplet.  Thus, the condition for the yakuman would not be met.

Then there is '''suu ankou tanki''' (四暗刻単騎), which features the hand with a [[tanki]] [[Machi|wait]], the winning tile may come from another player's discard.  In this case, all four triples are present in the hand.  This hand is closed only.

: ''Note'': This wait is sometimes considered worth two yakuman.

All four of the triplets must be concealed for this hand to be counted as a yakuman.  A shanpon is a double pair wait, where one of the pairs can be upgraded into a triplet.  If this method of completion is done by discard, then that triplet is considered to be open.  Instead of yakuman, the hand would instead be counted as a combination of [[toi toi]] and [[san ankou]], at least.
