I think flop is fine but when he reraises you on the turn I should be realy worried and when he shoves river what do you beat. you are so deep and I think that your betline screams flush and he still goes all the way

i think it is a clear fold on the river, you are beat

Hm, that's interesting spot. We are playing vs reg?(Anonymous tables probably have more regs than weak players)
Vs rec wouldn't fold river, but vs regular it is more complex. I would say normally reg will just call AdKx, AdQx on the turn and not raise it into a bluff vs strong range (after flop pot bet). What other type of hand he can have ?
1. Value - Nut flish
2. Bluffs - 66d? KKd? AdKx? Not too many candidates to go spazzy
Seems like fine spot to lay it down. River pot odds aren't exciting either

When he check-calls flop and check-raises turn I would be very cautious. Sets would probably bet flop or at least check-raise flop. There are a ton of draws on the flop so slowplaying sets doesn't make much sense.

River is really scary and puts up a four to a straight on the board. So river shove is very dicey. Will he really play a set this way? Maybe he'll play a straight like this, but being UTG opener, he should not have many 7s.

I think tipping point was the Turn check raise. RED FLAGG
not saying I could get away from it but I know I could lose less....... something doesn't feel right on Turn....
In my way of thinking I would say ok on the flop and chk with the main "idea" of using position for pot control to insure I see a showdown. ( barring a horrendous turn or river card)
I think I am checking flop here with the intention of tank calling all the way down.
calling down all the way sounds really fish.......But that is what I would do. Let him think at best I have an Ace and have him help me control the pot size. Since you Do have position, exercise one of its benefits and pot control all the way down.
God this sounds fish.

In theory you just don't fold a flush here I'm pretty sure so then it comes down to how exploitatively that you want to adjust. From experience and also database reports will show you that small stakes players do not check/call -> check/raise with a balanced range and are actually very far from it. He can't show up with a worse flush because you block T9s and 76s is the nuts so OOP has to be doing this with a set or a straight and I don't think that's particularly likely given how weighted your line is towards flushes so I'm honestly tempted to make a massive adjustment and just fold this on the turn at these stakes. Can't blame you for making the call but I'm not convinced that it's profitable because villain is probably massively underbluffing given that AdX has enough showdown value that it's not going to get bluffed and if they don't have the Ad you could just have the nuts and villains getting super aggro when you can hold the nuts is usually a sign that they know you don't have the nuts because they have it themselves.
