I am going to put a bet in here as well. It just seems to be villain should be c-betting anything he could 3-bet pre with except for pocket pairs under 10. Two broadway cards probably call for a c-bet here (either having made a pair or gutshot with overs.) Any kind of combo draw (flush plus pair or flush plus gutshot) should be c-betting here as well.
I think this check is often a give up and really the opportunity for hero to steal this one. Also, I don't think we know if we even want to make the straight here. As tempting as the free pull may be, one of our outs completing a flush, not to mention all of them complete AK. (or K9 for that matter.) I think the only way to play this pot now is to steal it, and I don't think checking the flop tells any credible story that we outflopped two eights by the end unless we catch cards that further scare villain.
I say bet-fold if raised is the best line here. Low-risk high reward, and not a devastating fold if necessary given how bad this board is for us. If villain just flats, going to re evaluate whether or not to fire a second bluff on the turn. If called my perceived rage is still the pairs under ten, ten-x, and maybe a-hi gutshots that he decided not to c-bet for some reason.
