WaitEh?RonOr perhaps are you hungry?Oh my, what's the matter?Onee-sa~n!Found a suckerNext is this, "san'ankou", a yaku worth 2 han.
Just like the name says, it's a yaku where three of your mentsu are ankou.
It's fine if the 1 other mentsu is shuntsu, and/or is made via fuuro; if it's a minkoutsu then all of your mentsu are koutsu and you also get the 2 han yaku "toitoihou".
It's also easy to turn this yaku into "suuankou", which is yakuman, by having the fourth mentsu also be an ankoutsu.
In example 3, if your agari is via tsumo then it's suuankou, if via ron then it's toitoihou san'ankou.
In example 4, whether via agari or ron, it's a tanki wait for suuankou!ExampleIs san'ankouIs toitoihouSuuankou if tsumoToitoi san'ankou if ronTsumoTanki wait for suuankou regardless of ron or tsumo......haaIt really is boring doing this alone.What's the matter?
Were you bullied by that scary transvestite again?And I've run out of my supply of tacos.Truly, just as planned?
