I would also toss the

. The

will complete that 3rd chow and there are 11 of them left.
After you draw one of them, toss the

, riichi pinfu.
To rely on that

for a straight doesn't seem like a good idea to me but if you do happen to draw the

or the

after you toss the

but before you riichi , you could toss the

to add tanyao to the mix and then riichi.
riichi,pinfu,tanyao,menzen ron-----3han, 30fu, for 3900 pts
riichi,pinfu,tanyao,menzen tsumo--4han, 20fu, for 5200 pts
About half as much without tanyao.
Now that I look at the point spread, I wonder if tossing one of the cracks and going for the straight should be considered.
If I get it, the point totals above would double (substituting ittsuu for tanyao).
I definitely would not chi the

and open the hand. Need to riichi. Could end up a mangan (5han,20fu or 4han, 30fu kiriage).
I hear Washizu laughing? Hold on. I just realized that you have to draw that

before you complete the crack chow or else it's a penchan wait on the

and no pinfu. (and no mangan). The odds don't favor you on that one.
Think I will stick to the original plan and toss the

.
It's only East 3. First part of a long journey is a single step.
