Hello runitonce, this is my first time posting here and i'm super new to this so Please bear with me (and my poor english).

Basically this hand took place a few days ago and imo its just crazy.

Binds 100200,

english pro raises from utg+1 to $600 and i 3 bet to 1.9k with ATcc he calls. This is the first time we are playing each other so i dont have much reads on him. The only time he got involved vs me in a pot was i punted with k5ss and hit Ac 3c 5d 5d 9h when he called down 3 streets vs my bet bet bet.

Flop 9s 4c 5s

check to me i cbet 2.5k he calls.

turn 3c

check to me i bet 6k into 9k he calls

river 8d

check to me i bet 16k and he calls pretty quickly with AJhh.

Now i dont really know what to make out of it but apparently i'm really interested if any of you guys can figure how what ranges he feels i have in my range that can profitably call in this spot? I think my 3 bet range consists of hands like AT,KQ,KJ+ suited and some suited connectors like 76+. I dont think i'll ever bet kq/kj  high on the turn even i pick up a fd because its probably better to realize my equity by checking back.

On river i basically bet KK/AA/QQ,2 pairs ,straights...bluff with AK/AQ sometimes and in this case my AT obvly. Checking mostly 9T(Wont bet turn)...JJs and some AQ AK that i decided not to bluff with.

How good is this call vs me? Thoughts pls
