3bet turn or wait til river?

[philipsaurus]

this is against mizzles from about a week ago. 3/6, we are 1400 deep and are playing pretty standard. he opens utg to 21. i call on the button with 88.

flop is K84r. he bets 40. i call.

turn a 3, that puts up a fd. he checks. i bet like 115 . he check-raises to 350 straight or something similar.

should i bomb the flop, or call and try to raise blank rivers?

fwiw, i think he is weak here. that is just my intuition tho.
