Dealing into mangan-ish is 4th place, dealing into less is not. 1st is more or less out of reach.
Do you discard your manzu block or push the pinzu, and if so, which? Discarding 1p has more acceptance to win and probably deals in less than 9p, but it also hurts more if you deal in.
Also not sure that it was a good idea to discard 4m, but that one was pretty tough with very few safe tiles.
