First post here...so forgive any mis-use of poker jargon.

Eager to get feedback on how badly I butchered a hand in a fairly loose (ie late Saturday night Las Vegas) 1-3 game. I was 500 deep and Villan had me covered.

Was dealt 89 in MP. Villan immediately to my right raised to 15 and I called. 1 player called behind me.

Flop comes 672

Villan checked. It had been a very bad game to c-bet, and with a player behind me I checked. The player behind me checked also.

Turn was the K, giving me an open ended flush draw. Pot is about $45.

Villan bets 20. I raise to 65, planning to bet around 120 on the river regardless of what comes. Players behind me fold. Villan thinks for about 30 seconds and calls.

River is a brick..the 3

Villan checks.

My question is, how should I have played the flop/turn, and is this a good spot to bluff the river...with all the draws having missed?

what is Villain's image?

bet flop

as played, check river, villain most likely calls since every draw missed, his line seems like AK or KQ

I would have folded pf b/c
1. 5x is a large open
2. we are the first caller so we might have to play a hu pot and this hand does better multiway
3. we are in mp so we will be oop to anyone who calls who isn't in the blinds
4. we are in mp so there is a better chance someone wakes up with a hand and 3bets and we have to fold
?. how deep are the people behind us, the deeper the better

If there was 1 caller and we were in late position I think this is a good call, but not as the 1st caller in mp

OTF when villain checks his range becomes very skewed toward AK/AQ b/c the vast majority of the time any overpair will bet. That means our semi-bluff really only has to get past the player behind us so I would semi-bluff. The guy behind us could have TT-JJ but he won't raise and we have outs when we get called. 66, 77, 88, 99, are a big part of his range but the fact that we can see 1 of each of those cards makes those hands less likely and even if he has 66-77 he will raise and we can fold easily or he will call and we have a chance to felt him with a T or 5

I bet $30 b/c that seems like enough to fold out overcards

OTT I just call villain's $20. Everything he's done in the hand is consistent with AK (raise large pf in ep, check the lowcard flop to 2 players behind, then lead the K on the turn). At this point the only hand he has to be afraid of is a set so he's not folding to a raise

OTR I check. No draws hit except 54 so he's not folding TPTK

Perfect.

Fold pre.
Bet flop like you have a big hand.
As played, call turn. Raising here can get you re-raised and with only one card to come you are then priced out of calling.

River: Need more info on villain. I do bet this river fairly often if I feel villain's range is skewed towards having flush draws in this spot. However, only a very small subset of villains will fold AK in this spot.

I don't hate the call, as long as you understand that its very risky, and you could potentially be setting yourself up to lose $15 without even seeing the flop. Make sure you have a good handle on your opponents and your table and your image before you flat call mid SC from mp like that. Honestly you got lucky. A competant player would notice the action and might look to make a squeeze in that spot from lp.

As played, bet the flop...no reason to check here. There's no such thing as "a very bad game to c-bet". Just mix up your c-bets accordingly and they'll show profit. And technically this would NOT be a c-bet, as you were not the preflop aggressor. You have what looks to be 8 clean outs and the pre flop raiser checked to you. BET.

No need to raise the turn. Just call. You missed, so dump the hand OTR.
