5 handed I get 678Tss in MP and limp, LP raises pot, SB calls, folds to me, I call.

Flop is , I don't have any diamonds. SB checks, I ????

PFR is aggressive so is likely to CB, but doesn't raise a lot so a real hand is likely. We are both 100ish BB deep.

What is your line for the rest of the hand?

Edit: It was a not a on the flop.
