Suuankou
Suu ankou (四暗刻) is one of the standard yakuman hands. This hand consists of four concealed 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.
