2/5 game that is a big limp/call fest

villain - late 40s, have only played with him a few times, have only seen smaller bluffs and big bets with nutted hands. doesn't believe anyone and is a big calling station post flop.

hero - solid TAG, but viewed as mid 20s LAG - haven't shown down any hands early in this session

Hero - $400 J7 (BTN)
Villain - $500 (UTG)

Villain straddles $10, 3 limpers, Hero calls, BB calls, Villain checks.

(pot $62)
FLOP: 54J

checks to Hero, Hero bets $40, Villain calls, everyone else folds

(pot $142)
Turn: J

Villian checks, Hero bets $100, Villain calls

(pot $342)
River: 2

Villain bets $200, Hero....????

fist pump call? sigh, call, nh? sigh, fold?

The limp with J7 is bad. Raise/Fold pre. Now you are in this horrible spot where you have 3 jacks and your kicker is the 3rd worst kicker. You lose to almost all Jx. I don't mean to be arrogant here, but really the only advice I can give you on this one is to not limp in with J7. At this point in the hand, I think you should probably fold unless V is bluffy.

Weird line but that is what calling stations do.

Almost any jack beats you and A3 just got home. It can be tough to fold when a line makes no sense and you think only a few hands should reasonably beat you. But remember that a $200 bet is a huge bet to a calling station. Usually reserved for nutted hands. Sigh fold and make it look easy?

He's giving you 2.5:1 on a call, so you only need to be good just shy of 30%.
What hands does he hold that beat you? Jx is unlikely because of card removal. I think a J as low as JT check/raises as least the flop. Same goes with a strong flush draw, and maybe even the OESD. There are only 16 combos of A3, maybe even discount more for a folded A somewhere.
I think it's close. How likely is he to turn a bricked draw into a bluff? And his bet size may be small or large, but your info wasn't specific enough to tell that. Like I said, I think it's close.

What do you think your hand looks like in his eyes?

does he having a sizing tell by betting 200 otr? is that a big bet for him?

if he only bets big with his value range then i can find a fold, even if his line doesn't make much sense.

The limp preflop is really bad considering with the straddle you're only 40bb deep In a normal 100bb situation I don't mind it, but not here.

Call river.

pre is the biggest mistake in this hand and what needs to be worked on to improve the most. I actually like raising to 60 a lot here. Takes the pot down a ton.

the limp on the button is a poor play IMO, you are accomplishing nothing with that play. i think every street you played was fine.

V's line us super weird but since you limped Vs range is everything which is obv brutal to play against. most Jx hands V can have would have you beat maybe A3ss or 63ss.

i think this line from an amatuer usually means a big hand imo i dont think you would barrell twice with air on this board in a blind vs button situation so i think you probably have to call but i wouldnt be happy with it

I agree playing this hand in the first place was a bad idea.

My initial thought when he fired on the river was that he was bluffing a missed draw; however, I figured I lose to nearly all other Jx and the 2 made me second guess myself and put him on A3ss.

After I mucked he flipped over 88 and proceeded to question, sincerely, "if he was good"

Disagree with this. Limps in straddled pots tend to be tighter than in regular pots. I really doubt that raising to $60 with steal the limps, and J7s will be badly dominated by most live players' limp-calling ranges.

Fold preflop. Fold PF > Call PF > Raise PF.

Anyway, beat Villain into pot and snap-call when almost all draws busted.

This is wrong. Calling pre is the worst thing you can do, and we are never dominated when called. Most people are going to call with hands like AK, AQ, maybe KQs and smaller pairs, where a c-bet will win Us the pot more than 50% of the time.

Fold PF > Raise PF > Call PF
