you should have reraised to begin with how else you gonna get any info

So how much should I have made it? Like 50%?

just 3x it buddy if no info on him. does he raise flop always wit the A an then check turn? alot of time in small stakes when they get called on the flop they tend to slow down on the turn so maybe try get check check all way to end or place a bet urself for more info on the turn my guess is he had like pair of eights or nines. if you raised the turn an he called then most likely he was slow playing the ace but if slow playing he would most likely have checked reraised flop. why did you decide to flat call with such a big pair pre flop? always reraise in these positions not often enough we get thes good hands so get value when you can buddy

And what happens when he shoves over the 4-bet pre? You have to fold.

I would prefer to check back the turn for pot control and call non all-in river bets. The amount we bet on the turn here makes the pot perfect for him to ship all his value hands on the river giving us a good price

I would definitely not be raising at any point in this hand.

I'm ok with betting turn and I think checking back is decent as well, though I really don't like your sizing. So you have JJ on an Axxx board, by betting you should be either trying to get worse to call or better to fold. I think getting better to fold is a bit of an optimistic and unnecessary play with JJ here so lets go with the vbet. You went quite large. What worse hands are calling for ~72% pot? I guess some will continue but for the most part I think you let him easily fold out some worse hands with the large sizing. Also, denying some equity from something like KQ is fairly important in a spot like this, but once again you don't need to bet that large to accomplish that. If I was going to bet I'd make it something under 40 cents.

When u call with J J here u should just play for set mining. And when an A hits and he checks that smells like shit so hard, I mean he knows it s a scare card even if he doesn't have he can easy represent it. I do like your bet on turn but make it smaller, it s ok to stab it somewhere, I would have done it on flop. And easy fold on river.

I think the line is great. Just the turn sizing makes no sense, it's way too big when there's little worse calling and no better hands folding. Around 1/3 pot would have been enough.

Once villain shoves the river it's an easy fold though. It's either KK or you got slowplayed by AK. He's never bluffing enough to call this off.

A lot of usefull feedback in here. Thanks a lot guys, I will try to consider all that's been said.

I think reraising JJ here would be quite a large mistake so preflop and flop I think are played perfectly.

On the turn I don't hate betting at all but I my preference is definitely to check it back with the intention of calling river bets. It will be tricky to get called by worse here as well as to fold out better so IMO betting here does not make much sense.

As played then the river is an easy fold, calling here would be an absolute spew.
