normal passive 1/2 table. Hero is playing TAG but may be perceived as looser than he is because has been raising a lot pre lately. 5 straddle UTG by fairly tight player, but has been tilting a bit lately. UTG+1 folds and hero looks gown at KTcc and raises to 10. Maybe a little lose of an open but HJ is not at the table so I'm effectively the HJ.
BTN - (52) is a bad, too loose, old man who calls.

SB - (350) calls, another old man who is bad but a little tighter.

UTG straddler (200) calls

Hero covers table.

Flop (74) KQ8r. checks to hero who bets 35. BTN calls all in. SB calls and UTG calls.

Turn ~ 220 7 which puts FD out there. checks to hero who x/b

river 8. checks to hero who bets 85. is this too thin on the river? Think i could possibly fold out some worse Kx that I'm chopping with. However these guys are passive so could easily have an 8 or KQ or something

Well played imo

Highly unlikely someone has KQ. I kind of want to shove river to fold out the chops. Or maybe go 170ish

yea thats valid. I know its kinda double thinking that i can fold out chops and get value but i thought 85 may get me called by worse sometimes.

Why betting only 1/2PSB on flop? After the small flop bet, I'm definitely betting the turn for value and to protect our hand.

Why $10 preflop? $5 straddle is on, and you basically min open with KTs?
I dunno if this is a raise tell with a weak hand that you'd rather open small with than call or if this is standard but this feels like a very small raise.
KTs might play OK multiway but you've got a tight player straddling (oxymoron, btw, tight players don't straddle), and you're min raising.
Put a real raise out there and force the straddle to actually make a decision instead of just an auto call.
As played, button, SB and straddle all call. I don't think that's an optimal result for your hand pre. I'd rather get this HU so I'd be more inclined to open to something like $20-30.
Which also provides cover for those times when you're raising with a real hand.
The small raise really feels like, I have a hand where I'd like to see a flop but I'm scared that if I limp, someone else might raise big.
Button has $52. If he has a hand he wants to play, he's calling $10 or $52.
Did you hope button would jam over the top of your raise? If button had jammed, would you have called?
Bc if I am button, and I am willing to call $10, I'd probably jam pre.
I don't like preflop here at all.
Flop, turn, river all seem Ok, I guess. I can't get past preflop to turn my focus to the other streets.

That is a mistake in OP i did open to 20 thats why the pot is ~80 on the flop. Also straddler is tight but is tilting. A player at table that knows him was visibly surprised to see him straddle

I don't understand. Did YOU turn a FD?

This.

When you bet flop, you gotta figure BTN shoves, in fact I would have just bet 50 because... well, because I'm a dick I guess. I don't want to give him the satisfaction of riding tall, proudly announcing all-in. I'm looking for a sheepish call. Anyway, from the time I raised pre I would be assuming BTN would shove, and would be worried I would be behind if he did, and would be figuring I would make enough money off of that dope who straddled to make up for it.

Granted, with this flop, we are probably doing OK-ish against BTN's shoving range, but still.

When you say "flush draw" I'm thinking, "payoff." It's better than that, look at all the straight draws out there. Don't be a nice guy, be like me. Be a dick. Make 'em pay to play those goofy fish draws.

Haha good question, and if so, it's particularly important to maximize value OTT against the possibility BTN is on the A

Which player is folding a Kx worse hands? Are the players in your game so bad that they don't know the Q plays?

The big mistake is playing play pf. On the river, you made a bet that no worse hand will call and every hand equal or better will call.

$85 is probably too small but with a sizable enough bet you can absolutely make Kx fold. On the river you are betting into a side pot, since button is all in for the main pot. So if you are calling to chop, you are chopping the side pot with no certainty about the main pot. I'd fold some Kx here myself because it isn't a hugely profitable spot.

no there were no clubs on board. I pretty sure the turn put 2 diamonds up

results. Hero bets 85. SB folded and UTG called. BTN flips over QT, hero showed KT and UTG mucked.

I think a big and small river bet each have benefits. I think i was more in the value mindset and thats why i chose small but big to get people off chops is a good choice too IMO.

If you are going to bet the river, why check back the turn?
