I think this is a pretty interesting hand that could be played in a lot of ways. It was played by a friend of mine and the only information he gave was that over a small sample he opened the CO 23% and one note saying villain 3/5bet shoved 78s preflop. I don't know hero's actual 3bet range (yet, I will ask). We couldn't come to a consensus on the best way to play this hand, so I'm asking for further input as it has been bugging me.

This board obviously smacks a tight CO 3bet call range such that he probably never folds the flop, but my question is mainly how to construct our entire range in this spot on the flop and turn.

Do we play a simplified cbet only strategy and potentially sacrifice EV (how much, if any)?
Do we play a mix of bet and check/x strategy?
Do we only play a check/x strategy mixing c/c, c/r, c/f?

Where do you think this actual hand belongs with respect to your flop/turn strategy?
If we do have a cbetting range, do you agree we should check (and only c/c if we continue) our entire range on this turn?

Alot of questions.. thank you for any help.
