Bluff catcher or insta fold?

What is his calling range on the flop?

You have straight and flushdraw and OP on turn, why do you checkback? (if not intending to call his river bet)

As played I would fold, as we didn't gain any information on the turn to further narrow down his flop calling range along the way. However I did notice from other posted hands you go very often from betting pot on flop to coming to a complete halt on turn which in some spots is acceptable I guess, but here I would have Cbet for sure. If you checked turn because you felt you were already beat on turn, then you are also already beat on river. If you think he hit trips on turn but not a boat, then you have no way of knowing the J of spades filled him up or not. The only thing is that vs a tight(er) opponent looking at the river I would consider only being up against Ahi flushes and boats+, which would make it a fold, but this guy has pretty loose stats though...I would also say he would raise nutstraight on flop in a 3bet pot as there are so many ugly turns, fold out his air, stays with sets and top two pair and maybe stick around with a nfd. So I think you are beat here most of the time.

Raising from the SB he can definitely have a lot of AA with twio spade I think. But three bet of 17% is very high (<<sample though) . Two pair is possible I guess, 9TJQ two spades could flat. I am not sure how to use equilab to apply ranges so it is very awkward for me to analyse what my calling range should be on the river. I know I get 2:1 here but I was so leveled at the time i didn't know what to do.

So turn check back is poor here considering his range has fewer 9xxx hands in than mine?

Well he 3bets with a lot more than aces.

But when he calls that flop, I am pretty sure he has something. Wraps are impossible, and he shouldn't have a straight when he just calls. So what is left are 2 pairs, sets and flush draws. On the river pretty much everything got there. I mean, it is really hard to give him a hand that doesn't beat you on the river, and he pots it. You have 9th nuts or something.
