Literally my first hand after sitting down

V1 (700)- 55 yo white male
Hero's Image (700)- 25 yo white male

Preflop (7):
Hero is CO dealt AT
1 EP limp, Hero raises to 25, V1 calls from BB, limper folds.

Flop (53):
KJT
V1 bets 45, Hero calls.

Turn (143):
T
V1 bets 55, Hero raises to 200, V1 calls quickly.

River (543):
Q
V1 bets 230, Hero folds.

I know raising is an option on the flop, I felt like the psb donk could be pretty strong like 2p+ and made flushs.

Then on the turn he bets much smaller relative to the pot size so I think I might have the best hand and could have a lot of outs. Though I could have just called getting a good price, I think that might have been a better play.

On the river it looks like I am chopping at best, I think if he was bluffing he would have just went AI.

I like flatting the turn.

Without reads...believe this is a fold.

Line looks very consistent with a mid-suited connector flush. KQ seems to be the only possible hand in his perceived range that you beat here and you're simply not deep enough to bluff villain off hand. Also, agree with flatting the turn when you have villain showing up with aggression on flop and turn.

I also think that you should flat the turn. I think it will be hard to get many worse hands to call since they will be scared as hell of that board. I mean can we really expect KQ, K9, or even KJ to call a raise. I don't think he has hardly any Tx in his range that leads both flop and turn that isn't now full. And, he can definitely lead flop and turn with straights and flushes. So, I think it's bet to call turn and reevaluate OTR.

As played, the river is a fold. You have a bluff catcher and I think he has almost no bluffs on this board with his line. If y'all were super deep and had history, this would be a sick spot to raise with both of your blockers similar to a PLO hand.

this is a boat...like a lot. i know we hold the 10 but i think this is J10/Q10/K10 more often than youd expect, depends a lot on how wide V defends bb. when its not were still chopping at best or losing most of the time. ya fold river, pretty sure im raising flop though.

Yeah if he filled up that would explain the small turn bet.

Why did you raise the turn? Flat seems much better.

Rest of hand is fine.
