reg going nuts in 3 bet pot

so this guy is a 20/15/4, pretty solid all around, runs really good against me :(. anyways, he likes to play me very passively because i think he sees me as a relentless spewtard. we have a good amount of history. ive never seen him take this kind of line though. this was my first hand at the table, and he snap called pre, and snap called the cbet, and then very quickly bet the turn, and he certainly isnt the type to flat AK oop bvb. although he might do it with AQ.

oh relevant stat btw, he folds to 3 bets 82%, 4 bets 5%.

Weird. I fold if it's the first time he's tried this. There's no way this is a bluff since he's putting all but $60 in. But it's also a dumb line to take for value if he views you as spewy like you said.

Still fold though.

this looks like KJ or A10 to me. His river line is kinda dumb but I think hes betting for value 100% of the time here and afraid the A is gonna slow you down which is retarded

I really don't like the three-bet preflop. You are folding out all hands you dominate that you want to keep in. Fold now
