It's a good range for people, sure, but not these two people. Op I think you should range these villains much wider according to your description of them. K10, KJ, K9, all AdXd combos, 8x + fd.. etc.

It's not the most favorable spot but turn card changed nothing. I'm almost never folding this hand given the history and the type of player V1 is. If river is blank, I'm stacking off.

at a casino??? lol why would anyone 4bet AK??? god im bad at poker.

usually you aren't good here against most players but against these two specific players how wide are they? I am calling and reevaluating river

Turn call seems mandatory against player described, but i am very concerned if v1 sticks around

I'm confused on what OP plan was here. You 3bet pre with apparently no FE and very little nut potential. I would assume the primary reason for doing that would be to get paid more when you flop top pair. As far as the action goes, even as a weaker player, wouldn't be surprising to see V1 adjusting to V2 and not contemplating that he should be in huge trouble against hero's range.

OP, do you still like your 3bet and think you just lost your nerve, or would you flat pre if had a chance to do it over?

AP, of course you are gonna lose often calling down, but this is a triple up situation obviously.

I have not read the spoiler or any posts after it.

First of all the 3bet - I'm fine with 3betting in this position with this hand vs. these opponents but I absolutely despise your sizing. This deep vs. these fishy opponents it needs to be much much bigger, something like 120-140. The goal of a 3bet should be to narrow your opponent's range by reducing the spr - making it 70 never does this - both villains are going to call with 100% of their range when it's this small.

As played, flop call is fine. And on the turn we gotta be feeling good - as far as 4 card boards go, K837 with one flush draw is well above average for our hand. If we start folding spots like this vs. players this bad we're simply going to be folding too much. Especially as played - I'd expect both villains to c/r 2 pair+ hands on the flop and play AK/AA more aggressively preflop more often than not. And now the turn is a total blank. So only question for me is call or raise? Given that V2 is now committed to his hand, I think raising to ~1.1k or so is better. There isn't much merit to giving V1 a good price to come along when our hand is a bit vulnerable, there are some bad rivers, and V2 isn't going anywhere.

the 3bet is super bad

don`t fold turn and bet river if it`s checked to you
