Villain is a reg, raise flop cbet 20% I think we get raised a ton on this text. as a bluff so 3betting should show profit on the flop. I'm not usually 3betting my own sets there but could do some time - so I guess broadways which bluffraise are just folding. Ofc doesn't make that much sense to bluffraise worse hands out but it's too weak to call and kind of vacuum spot against an agro guy and we have a gtsht which is why I think it's okay hand in bluffrange since he also is raising bluffs on the flop.
River I don't get what he wan'ts by betting I usually think he has 77,88 there but we can rep Jx and even QJ by shipping the river and there's imo no way he could get there w. those hands after flop action. So pretty good spot to bluff the river imo.

and the like).
