3bet pre or fold. I think A8's can still be in the 3 bet range. Flat is meh imo. Blinds will join often due to price even OOP. BB flats... very weird.
Flop is great. Cbet this is fine imo. His PP are calling it often. I block the flushdraw, so I'm probably behind now, but I want to start to build the pot.
Turn I hit. Decided to check because the board is not very dangerous and to maintain his bluffs for the river. 3bet pre and a double barrel holding the A♣:... I think check is better than betting. He won't call with much worse here imo. Check-raise even less.
River he checks I bet 1/2. I think my hand is the best. But then he check-raises on the K.
Don't believe he has KK often. Would cbet OTF imo.
77 don't know if he calls OTF without a club. TT are possible. Check-call, check, check-raise... What the hell does he have here 
KK check OTF?
3bet is fine, but this is a hand that doesn't mind playing ip multiway.
i'm simply 3barreling. as played you call i guess, though i really like his line if he has any nutted hand here
It`s weierd to guess which hand villain has here.
He can have got 22-TT some Kx and of cours total air and try to bluff you out (not very often)
I guess villain has some times 22 or T2 and sometimes Kx
I guess the hand is played fine.
You have to pay 38,1 bb in a pot which has 101.1bb, so calling with nut flush is fine, even if boats are possible.
Just 3ba please. No real reason to check back OTT.
As played hard to fold with that line. If he has better so be it.
A8s not in my 3b bluff range here but why not. But for god's sake, bet for value when you hit... You must throw away so much money by playing like that 
Easy 3 barrel for me, if you're beaten, shit happens ; but come on you have nut flush in a 3b pot !
His calling range to my 3bet would look something like: 77-JJ, AQs-AT's, KQ's.
I have the A♣: which blocks tons of hands in his range that would be drawing OTT and possibly call / check-raise.
Basically Ax hands are folding. KQ drawing to a flush can call. PP with clubs call. Can't see anything else.
By checking OTT I allow him to do what he end up doing OTR. He knows he doesn't have lots of SD value, so bluffs, either by donking or check-raising.
I'm creating value by checking OTT not losing. This is one of the spots where I think 3 barrels don't make sense.
Either you have stats over thousand of hands to have such precise reads on your opponent (especially that he would eventually x/r OTR as a bluff in 25NL) and maybe I would agree, either you're making questionnable assumptions about a guy you don't really know. I would need solid reads concerning his bluff frequency to play like that.
Yo,
3b PRF vs unknown with 92.6bb stack is really out of line for me and it is snap fold for me. When BB CC you with 121bb ES lmao your red light should go on, that he's very tight!
OTF is 100% check back vs BB, because we simply don't have enough FE+E to make it +EV!
OTT it is obligatory bet 0.5x for value, and you missed it!
OTR b0.5/c is the best for me.
I wouldn't personally 3bet preflop but I guess it could be ok. As played, I would always barrel the turn and river for value and call a raise.
Preflop can be fine. Flop is however a x for the reasons vengeance said. As played, barrel turn, if u wanna y so badly, why not x weaker flushes and go for value with the nutted ones?
