Live $400 wpt deepstacks

Eff stacks 34bb and opponent covers
There is a bb ante
I raise in MP T9dd 2.1bb
Solid competent CO 3bet 5.3bb
I call
Flop 877r 1 diamond
I chk CO bet 5bb
I jam around 29bb

1. I am unsure if preflop I should peel given how short the stacks are. I am getting about 3-1 and I gave him around 7% 3bet rng which gives me 40%.

2. I am unsure of flop cr jam. I could call flop and bluff river if turn chk chk.

Thanks.
