I raise flop to get value from worse Jx (although he sometimes has better) and draws. (Side note: if he 3b me, what's my move? I feel like it's a meh fold, but IDK.) On turn I bet (folding to raise obv) for value from draws, but I'm not sure about this. On the river I figure that even though he sometimes has the 8 I'm still getting value from two pair and (maybe) QJ+, so pretty easy shove.

Discuss.

I like just ch/call with our top pair. Our top pair isn't that good for value from lot of hands, and on turn OOP we can get a lot of trouble in big pot.

As played shove is standart

Early I probably play kind of pot controly because I want reads and board texture, so c/c flop, lead like Jx Tx turns c/c rest etc etc

Early on also is it better to lead/call and pot control turn to see if he will be folding to them? We get more value (if we lead/call) on a pretty wet board, protect our hand a bit with folds. Giving them the opportunity to cbet or worse check behind can that be figured out later and on a dryer board?

on the river u get value only from two pairs(maybe not even that)
and unless he is a calling station a jack wont call;
it is highly unlikely he has two pairs(he would have played them very agresive);
hands like J8, 78 , 89 makes a lot of sense as does a flush draw;
the river is so bad that u can check call at most;
i will simply check/fold instantly
but it's your decision;
but i like flop and turn, maybe a little agresive but that is not a big mistake

this

If he raises all his Jacks (which is rather unlikely), there are 6 better jacks in the deck on this flop (AJ, KJ, QJ, JJ, J7 & J6) and 6 worse jacks (J9, J8, J5, J4, J3, J2). Although there are some blockers for better jacks, the fact that he probably folds J2, J3, J4 makes your raise not for value about a random J imo. It is against most draws though.
I think leading this hand or check-calling the flop is preferrabel over a c/r (given you don't have any reads). Also: I don't want to see a shove if I c/r here and rather avoid getting into that spot vs unknown.

As played I think river = shove > check-call > check-fold. (Shove in the hope to get called by two pair or even just one - you'd be surprised sometimes. Check-call if you put him on a missed FD that might try to bluff the river.)

If you give advice to OP I hope you beat these stakes yourself? No offence, but I see a lot of struggeling $2 players on this forum telling the $5 and $10 players what they should do...

c/c flop, we aren't that good vs his GII range there. river is pukey but there is so little money left that jamming it in can't be too bad

I would c/c the flop, you beat only about 1/2 the combos of Jx he can have, and if he's not 3xing otb with stuff like J2o, even less than that. As said you're not doing well vs a 3betting range. I would want to have an aggressive dynamic/good read to be c/ring here.

River is an EZ jam given the stacks.
