Do a review by taking all your range in this situation and see in what category TT falls into. I don't know how your range looks like here but TT is good enough for me to call, he can even bet Adxd like this and chasing his draw that you already have beat. You would have to decide what to do on the river, thats where people get really honest when it comes to their hand strength.

I would almost never fold this spot vs fish. He will have it some times but as you said they come up with a lot of random hands very often as well.

never fold unless someone's like 15/12/2

I would call down a lot of rivers to be honest cause TT is the top of my range there. Id always 4bet JJ+ vs a fish and that sizing so

Against a gto bot it's an easy fold. Against real people you can exploit their underbluffing by folding or their overblufing by calling down. Just figure out what kind of player he is. Btw on turn Im not folding esp against a fun player
