Shoving KHFD + GSSD in 3bet pot

I can't figure out the best play in this spot.

Maybe I should check back because...

- when I get it in sometimes I’m against the Add in which case I’m crushed, (30% equity vs Add)

- and he might try to bluff turns that hit me (I need to have some strong hands in ck bk range)

- or I get a free card against a made hand like a straight / set that was going for a ck/raise

- even if I get it in vs. worse diamonds, I’m usually behind unless he has no pair w/ like FD + GSSD (ex. JTdd, in which case I’m 50-50%)

- BUUUUT then again I fold out TT, JJ, QQ, KK which I have like 50-50 against. (but some of those I can fold out on turn a good amount of the time)

all that considered, i'm leaning towards a check back and to shove with my Add hands
