easy fold?
I was betting to get value from the flush draw. I presume he raises any set there (flop or turn) with a set.
Is this river shove Ax that made two pair or a hidden set?
Can this be a Whiff flush draw?

Any advice is appreciated.(new to the stakes!)

I think it looks good if you folded. I dont think regs are donk jamming missed FDs like ever and we beat no worse hands for value

I c/f turn; dont mind checking flop either

Turn bet is fine considering there's a fish still in. Also, bb should be squeezing AJ-AQ pre and should be c/raising flop with sets/two pairs so we're going to have the best hand quite often.

I mean, you could be right; wouldn´t make all those assumptions though.

i think, button is going to call (I mean not raising anything) his whole range here OTF and we are probably behind it, even when its reaaally wide, like:

equity win tie pots won pots tied
Hand 0: 42.022% 39.25% 02.78% 20204 1429.00 { AsTc }
Hand 1: 57.978% 55.20% 02.78% 28418 1429.00 { 88, 22, AQs-A2s, KdQd, KdJd, KdTd, QdJd, QdTd, Qd9d, Qs9s, JdTd, Jd9d, Td9d, Td8d, 9d8d, 8d7d, AQo-AJo }
-------
Then adding the real vill into account, we are sooo behind their ranges and i kinda disagree, that vill is going to c/r 2p / set everytime on the flop

equity win tie pots won pots tied
Hand 0: 13.160% 11.28% 01.88% 126139 20975.17 { AsTc }
Hand 1: 36.064% 33.47% 02.60% 374147 29020.17 { 88, 22, AQs-A2s, KdQd, KdJd, KdTd, QdJd, QdTd, Qd9d, Qs9s, JdTd, Jd9d, Td9d, Td8d, 9d8d, 8d7d, AQo-AJo }
Hand 2: 50.776% 48.09% 02.68% 537653 29979.67 { 88, 22, AQs-ATs, KdQd, KdJd, KdTd, QdJd, QdTd, JdTd, Jd9d, Td9d, 9d8d, AQo-AJo }

We bet into 3 ppl on a pretty dry board, so I doubt btn is floating ever and bb (vill) cant call all the AXs ones or so; think, all the ranges are pretty strong and ATo doesnt do great against them; therefore i thought about checking flop to keep ranges wide and see how ppl will react

Looks like he's turning something into a bluff, to be honest.

He can't have As2s and 5x seems about as rare. A flush is basically impossible and a five would be heavily discounted. Weird.

I think you're ahead til the R, the button could easily have a 56s, 54s as he will be in position with lots of ppl in, if he has diamonds it makes perfect sense

I guess I can't definitively categorize him as a fish since he could just be a short stacking reg.

Yea I change my mind, I would like a turn check.

It is interesting to note that if he isn't value betting a five like this or just doesn't have a five in his range to get to this spot that this hand is (AX) is essentially the top of your range.

If he value bets a wide range like this or will not turn hands into a bluff in this spot, then fold.

He can't have Ax of spades as, well, you have the spade. This bet just seems too weird to me, without being in the situation its difficult to tell, but I would probably call it, I think he turns over busted flush draws all the time there. It's hard to see him doing this for value very often.
