cuz he has 2 pair

From experien min raise flop, 1bb bet turn and 3bet is the nuts, so clearly fold.

Also if he min bet 1bb flop, I am raise and then he again min bet turn I will just call or raise and fold, since is nuts line from fish.

Sneaky fish
id fold to shove, 1bb bet is fine raising.
Curse poker goods for pairing the deuce and not another card.

raising turn is fine when your plan is to fold to any 3bet on the turn since it obv means 2pair+ on this board texture ( which is exploitable by a good reg but not by a fish like this).

its also an option to just call the turn and take notes on river sizing to exploit the player later on. its just a tptk hand and when you win or loose small pots against this opponent with your marginal hands like this ( tptk has some showdown value but cant stand a 3 bet from the average fish on this board texture) and WIN big pots with your top2 pair+ hands your winrate will be exploding without risking too much with tptk.

you could also min 2 bet the turn and see what he does. maybe he interpretates a raise as strength and does not pay attention to the sizing so his 3 bet always means 2pair+. then you can easily fold and loose less BB's in that spot.

Gameflow idea: when you see fish calling with J2 in the BB i would increase my preflop sizing in the next orbits and tighten up when stealing, since he'll still call with weaker hands and you play bigger pots when youre a big favourite :)

fold to river shove on turn..

minbet/3bet is very strong.just fold to raise OTT

i perfer calling turn and deciding river ,your hand doesnt need so much protection and doesnt have so much value vs his line as well.

You can definitely raise the turn "bet". And probably just a fold versus a 3bet shove, the odds are poor, his line is strong and you're very fucked versus value.
