villian is regular, seems 3betting more than GTO suggest. So I would be both calling and 4betting more and put more prssure postflop (but nothing crazy, touch more of everything). I know that pre is loose call but 2 factors combined seems solid (3bet aggr, small size)

Flop - not sure what to make of his check. It is reasonable play of course, I belive we can discount AQ/99/QQ/A9 super often from his range since they dont like checking.

Turn - I need to put money and be polar. AK+ I think and, since I wont have many of AK anyway it is 2 pairs+
When I get called in my head thoughts that it will be hard to have enough fold equity on the river (just my thoughts)

So here is the question? 1) Would you bluff this river and what size? (not this combo I suppose since Tc isnt nice blocker, maybe some T8hh)
2)If you are IP and have AJ/AT or A5 for example are you willing to herofold? (vs big size)
