When there is a riichi from oya, the average points that you lose if you deal in is around 9000 points so unless you have a good reason, you should bail or at least play 'safe' while pushing for tenpai. Your discards have very little information if you riichi now with the only suji as

. Suji is all about probability and because of the

, ron on

or

on a double sided wait is furiten so it is more 'safe and unlikely ' to get ronned compared to other tiles which are not sujis. Even if you're

is being held as a triplet already there is a chance that early on when there is very liitle information in your discard that it will come out if the person is bailing because it is the safer option compared to non suji tile, and if you have three, you can avoid dealing for three discards if it goes through.
The fast

also means you are unlikely to deal into

shape, because your 'unlikely' to throw

early from

shape so it is more likely to come out even if the

is dora.
when I mentioned keeping the

, I did indeed mean throwing the

to try to avoid riichi on just riichi only as the yaku to get
from here there are very many possibilities to go to tanyao, pinfu or both which is much better than getting to tenpai then throwing away

respectively in turn. sometimes you have to go down a shanten to increase your probability of winning or increase you hand potential.
one example relevant to your hand is lets say you discard

instead of

, draw

and discard

and next turn draw

to tenpai on a tanki if you throw either

or
tsumo
it's actually better in the long run in this case to throw the

and not take tenpai to get
where if you draw

you get at least a double sided wait.
This is one example of going down a shanten to increase you hand value as well as your overall wait. Going down a shanten is generally more justifiable the earlier you do it and when it is a situation where you hand value or wait is likely get better.
My last point about going for tenpai quickly is the difference between oya and child. As Oya, your biggest weapon is riichi, no matter how awful you hand is, if you riichi, the best option for other player is to bail as I have alrady explained that from them, if they deal in, the average point loss is 9000 which is massive therefore generally it's generally better to try to get tenpai as quick as possible an riichi
If you are child, other players have more of a reason to push against you so you generally aim towards a good wait when and if you riichi. A fast riichi which is a suji wait is a 'good' wait but if the

was

and the

wait is not a suji, you might as well aim for a good wait by going down a shanten if your not going to riichi anyway on a

wait. That what I meant for the end of my post
