I almost folded flop. Obviously my hand doesn't play well as a call. Should this just be a flop fold always 3 handed? After getting 2 calls on the flop, should I give up on the turn? I felt like sets and naked flush draws have to fold, and probably A3 as well. So I'm really only getting called by 36 and 68 or sets with FDs. I didn't think either player had a set+FD based on flop action. I figured CO had NFD+overpair a lot and would have to fold which gives bad odds to SB to draw.

I would for sure donk this flop.

That does make a bit more sense than check raising. At least it's less of an investment.
