This hand is 2 shanten for itsu or sanshoku, and is already 1 shanten for a fast tanyao.
With the
we don't move closer to tenpai (still 1 shanten), and it don't fit with itsu nor sanshoku.
In the other hand, it will be hard to keep all the dots. I mean, if we make itsu, we'll discard two of them and keep the others for the pair. If we make sanshoku, the pair is likely to be from
,
or
, and
will be discarded.
The main interest in keeping them it to let open the iipeikou possibility, but I don't think we will go for it anyway.
So we can discard either
,
or
, depending on the others' discard.
All things equal, if we discard:
: tenpai with 34pin 25sou, 12 living tiles.
: tenpai with 14wan 25sou, 15 living tiles.
: tenpai with 14wan 25sou, 15 living tiles.
So I'll discard
or
now. The
may go away later if we draw a good tile for itsu or sanshoku.
