Given how drawy the flop is, I feel like if villain had a set he probably would just 3bet fairly often to get it in.

Assuming that, then KJ and 77 are pretty much the same here. (other than the fact that he has KJ a lot less often.. which I'm not sure is THAT relevant really).

Either way, I like betting this turn and throw up if jammed on. c/c sets us up for some bad problems I think.
