.5/1 live home game, stacks are 300 effective 4 handed. Hero has AhJd and villain has QQ. Villain opens to $2.5, D (hero) 3bets to 10, Villain 4bets to 21, hero calls. When I opened the flop, I accidentally exposed the burn which is the jack of clubs. Flop comes Js8s4s. Villain bets 25, I call, turn comes 4d, villain bets 65, I call, river comes 4h, villain shoves (for about pot), I call. I had been running super hot before this hand, and the players were starting to get suspicious although what I did before this hand was standard AFAIK. Since there are 2 Jacks showing, is it reasonable to assume that villain can be value betting as thin as 89s, 99, TT, as well as having some bluffs here? I do unblock all the flushes that would want to check the river (not sure if that means anything?) Considering all of this, especially the fact that I had been 3betting a ton of hands this session and that the jack is showing, is this a call?

I think you find a way out of the pot as soon as one of your outs is removed from play, when there are 3 of the same suit that you don't have in your hand, and when the board pairs with a card you don't have. Villain isn't reraising with a weak hand pre-flop. I think you wasted every dollar you put in after the flop.

Do you think that top pair top kicker is a fold on a monotone flop vs a 1/2 pot cbet? If you think that calling the 4bet is correct (which might not be correct) what flop are you calling a 1/2 pot cbet if not top pair top kicker?

If it was me and I don't have any information on villian. Defend AJo in a 4 bet pot seems loose although you are playing short handed. Folding can't be wrong here but the least I'll defend in 4 bet pot might be AQo+ 98ss?

On the flop roughly $42 pot and villian c bet 1/2 pot on a monotone board. GTO recommend betting 1/3 pot with a set or better. I don't like calling on the flop cause villian range unlikely have a flush unless AKss or AQss. He could have AKo with a spade and were only talking about villian bluff. Villian can still have all the pocket pair JJ+.

I probably mid raise to $52 on the flop and if they rejam I'll give it to them with top pair top kicker. Reraise here accomplish the betting aggressor and mostly they check turn which give us a free river. And call depend what is river and how much villian bet.

This is just all my opinion might be wrong. What you think?

The reason I defended the 4b was because the size was quite small and also because I think he was sort of tilted that I'd been reraising almost every pot (although I think it was correct). I'm not sure what raising the flop accomplishes, except for folding out his worse hands and getting called by better. other than some Ax with A of spades. As for the turn and river, since a Jack was exposed, I thought that the existence of a blocker to my best hand apart from Jacks and maybe Queens because we were 300bb effective, would mean that villain is value betting thinner than QQ+, and can definitely turn hands like AK AQ with a spade into a bluff. That's just my thinking. Also, as for the sizing on the flop, this person seemed like they mix 1/2 pot and check on every single board, so GTO sizings are out of the window.

If you are getting away with re-raising almost every pot; meaning you had yet to be played back at, it means the 4 bet either is very powerful(as they had yet to find one) or he is adopting to your style. From your description the first seems more likely. Assuming it is the first how do you feel your hand compares to their 4 bet range? You have horrible RIO(vs range not actual hand) if an A hits unless you get a J with it and as you demonstrated horrible RIO vs their actual hand if a J hits. You are acting like his 4 bet range and your 4 bet range are the same; as proven by letting you re-raise almost every pot without playing back at you they are not.

Fold to the 4-bet

Fold flop, not close, no justification makes it good short of "what if there was a terrorist attack and the only way to defuse the bomb was to call with AJo" level stuff
