[SH] JJ on CO strange 4bet pot

Bet on the turn

Pre I would call too since villain can be 4betting wide vs megafish.
OTF there is only 1 overcard so I would probably call here too. Ppl will cbet with hands that did not hit so often that we can call in this spot.
When he checks OTT I might go ahead and start betting but I guess this is ok too. When he checks river too it is likely that he is giving up but he might still be tempted to call with some Qx or weaker Ax because you checked that turn too. So when you have a chance to see a showdown, I would take it and check behind. Bluff shoving with a hand that has some showdown equity is not that good imo.

I think wihtout info that he actually cold 4bets light vs fish OOP, the call preflop is close.

I do not undertand why bet turn? Our hand is not vulnerable, we will not make most bet tter hands fold.

River I also think there is no value in betting.

And here I think I made a mistake calling this bet. I didn't have a hand really, now I see this and I wondered why I called this. But I did. Or maybe it was right?

I am also not sure without info about his cold 4bet range that we do ok on flop. He can easily have lot of Qx in his range, good draws and his sizing is more than 1/2.

River comes another 4. Daaamn, he checks again! Here I realised he'd fold to my bet easily, he probably have like KQ/KK and is so scared of ace on the board he'll fold them. So I turned my hand into a bluff, go AI, which is like 70% of the pot here and he folds.

I myself would not try to fold those hands, becauase I would not believe he is folding often. Maybe on the turn he hit AJ (if he has it in his preflop range) TP and so it makes sense for him to check turn and let you bluff. I just would not try to bluff a guy on last street when he cold 4bets preflop and cbets big but after this hand , we might assume that he is able to have not so good range this is a guessing game I think. So probably various options are not terrible.

We can always set mine preflop.
POstflop we can float once and bet when villain checks.

When villain checks OTT he is capped and we can exploit him by betting. He will fold a lot there. With our stack sizes we can shove turn.
Only hands villain could check call here are total nuts like AA and KJ, but we block KJ and he probably doesn't 4bet that.

Also hero hasn t aa e kj, i checkdown or i bet turn+river for make fold kk kq, if you bet only one street he fold only hand that you beat imho

Calling flop and checking back turn is not a good idea. Either fold flop or float and bet when he checks. What else do you float for? Catching a river bluff?
