'''Iipeikou''' {{kana|一盃口}} is a standard [[yaku]] involving two identical [[mentsu#Shuntsu|sequences]]. | '''Iipeikou''' {{kana|一盃口}} is a standard [[yaku]] involving two identical [[mentsu#Shuntsu|sequences]]. Identical means that both [[shuntsu]] must be of the same numbers and suit. This yaku also requires the hand to be closed. Any [[naki|open call]] ruins the yaku, even if the pattern already existed within the hand. If this pattern is found twice in one hand, an alternative yaku, [[ryanpeikou]], is scored. | ||

This yaku | This yaku usually appears as three groups of consecutive pairs. However, the rule interpretation views them as a two [[shuntsu|sequences]]. Potential acquisition of this yaku is best recognizable when five out of the six tiles are present in the hand. | ||
Note that iipeikou requires the hand to be closed. If you make any open call (chii/pon/open kan), iipeikou can never be scored, even if the call was unrelated to the identical sequences. However, the ''sequences'' do not have to be closed: if you declare [[ron]] with a closed hand, iipeikou can still be scored, even if the winning tile completed the 2nd identical sequence. | |||
