CO is a solid thinking reg from what I've seen, no specific history, runs ~ 21/16 with 40% fold to cbet. Blinds were both fairly bad loose passive fish I think.

Thoughts on villain's range and this and other lines?

Soooo.... explain why this is simply better than betting 20 yourself? I'd assume his range consists primarily of Kx or better, TT-QQ/A9 if he's saucy. And I think you fold out worse than Kx with a simple double.

think you played this hand all wrong.

FLOP: don't c-bet this...with two players in the pot the K hits a large part of the range...I would check the flop
TURN:
not only is villian saying they have a hand but he called the flop bet and then led out on the turn. without knowledge of betting patterns...villian is looking strong. bad time to come over the top with just a flush draw with one street left. I would fold.

Well, my thinking in-game was that there are a variety of straight draws villain can have on the flop, plus some medium strength one pair hands like 9x,TT-QQ, and some strong Kx+ hands. I think he mostly bets his straight draws when I check as it looks like I'm giving up and he'd prefer to take the pot down right there against my A hi or small pairs or what have you. Most likely I was overestimating the number of draws he can have and underestimating how many 9x+ hands he can have.

yeah i think i like double barreling here a lot more than check shipping as we get him off almost everything but a king or better for cheaper. Id even prefer c/c turn and c/decide river to check shipping if hes floating a ton or we thought his range was mostly draws.

I like betting the turn again.

but c/jamming u see a river for sure!

Unless the guy floats and bets the Turn a lot I think the 2nd barrell is just better.

The only real advantage otherwise is he folds some of his Kings to this move. But like how many Kings is he coldcalling with? Not many.
He can flat a set on that flop too.

You misread the hand history.

I don't mind this play against this villain. It's entirely possible he has KQ or even AK, as well as TT/JJ, and he will fold some, even all of those hands depending on his hand reading/opinion on you. You also get more money in the pot from hands that will often fold to a turn bet that you beat, like 98/88/draws/unlikely floats with air.

Obviously you're screwed against a set, but there's only 4 reasonable set combos. Against an opponent capable of folding 1 pair hands, it's probably a decent play, and folds more hands than just betting turn again.

u take this line with a set probably never.

This.

In fact your opponent is in a bluff catching situation imo..

dont know how often he calls but I dont think c/r ai is the best option in here..
I'd rather b/f turn..

But regs never bluff, so I should have AK/AA here like every time!

I wasn't trying to fold out better. Maybe he b/f's KJ/KQ occasionally, but for the most part I think if he's betting TP on the turn he calls a weird looking CRAI. I don't think there's any need to balance my c/r range here- rather, I should be looking to exploit when villain has an unbalanced betting range on this turn. Like I said, thinking about it after the fact, his betting range is not so unbalanced in this spot.

He's so rarely going to be floating with air here (with the intention of trying to make a play on you on later streets) particularly because SB is still in the hand. His range is KJ, KQ, 99 and 77 imo. If for some reason he has J9, T9, etc he's going to fold to a double barrel anyway. Especially since the 2 doesn't change anything and isn't a good double barrel card anyways. So it's going to be hard for him to float light or make a play on the turn if you barrel again. C/shoving is folding out the same hands you would fold out with a dbl barrel, and getting your entire stack in against a hand that would have called you and let you see a river. If he raises/jams turn I'm folding because I don't think he's doing it with less than a set.

check/call the turn usually. if you don't know what to do on the river after check/calling the turn, you probably need to check more stronger hands ont the turn.

you can also bet the turn yourself because people will float all kinds of garbage again and you can bet 2/3 pot roughly to give yourself a good price on the draw. as far as the river if i bet the turn, i'd be betting a spade river and check/folding a jack/queen, bet/folding a T and any blank i decide based on what he bets
