>>281237915Awai realized that Nelly's hand would have been a lot cheaper had she dealt in instead. By winning with a Tsumo on the 1-man instead of a Ron on the 4-man, Nelly also got the following yaku which doubled the points she got:
Menzen Tsumo (Tsumo on a closed hand)
Sanshoku doujun (Same sequences in three suits)
Chanta (Terminal or honors in all melds)
