The game is 2-4, 10 handed, early on a friday night. Bit of a slow table.

Villain is a early 30 reg who i've played a couple of sessions with, but no major history. He is somewhat taggy but definitely no nit. For instance in a previous session he called my btn raise from the BB with 5c2c, c/r'd on J63cc, bet the turn, and then checked river when he hit his club, later claiming he was hoping i would represent the flush. Stack is around starting point, ~400, maybe 450.

Hero is a 30-something Tag, running really well tonight. i'm definitely VPiP'ing more than normal due to run good. I got AA 3 times in the 1st hour and in the 3rd hand of the night i stacked the guy on my right with 99 on AK9. I cover villain.

OTTH:
Folds to Villain on BTN.
Villain raises to 14
Hero has 4c5c in the BB and calls.

People are probably gonna say this is a 3bet or fold spot, but i've 3bet like 4 times already and villain might get sticky pre. I also think he is wide enough on the BTN that we can call here. Might be a mistake.

Flop: (30)
955 rainbow.

I check. Villain bets 18. I call.

Standard? i debated c/r but its such a dry board. Villain is definitely capable of floating vs a c/r here though imo.

Turn: (66)
955 8s
brings a 2nd spade.

check, check.

River: (66)
955 8 4s
Obviously gives me a FH, also completes the bd spade flush

I check. Villain bets 90 fairly quickly. I think for 30 seconds, ask how much he has behind (villain lifts his hand to show ~300), i take another 15 seconds and shove.

So i usually i would just lead for 1/2 pot but his range seems to be pretty weak. I'd say he has A high or worse quite a bit here, which obviously cant call much. So i decide to give him some rope and bet himself.

When he bets 1.5x pot i assume he's either trying to get me off 9x or like 66, or he's got massive value.
Anybody just flatting here? It's hard for him to have a bigger FH but it's also hard for him to call with an overpair or flush since i can have all the full houses and river c/raises tend to be sooo valueheavy.

So let me know what you think about my line, as always all feedback is appreciated

Whole hand looks okish to me

Villain overbetting the river is somewhat interesting but hero should still be raising for value - raising less than all-in is certainly an option, not sure if villain will give you credit for any bluffs when you jam

If we are good and we think the Villain will call a shove a relatively low percentage of the time - say 20% - and will call a $90 minraise more often - say 80% of the time, assuming our shove amount is about 300 more that's $60 in +EV for shoving, and $72 in +EV for minraise.

If that's all we consider then a minraise is marginally better but it only costs of $12 in lost +EV to give villain a chance to make a bigger (about $200 more) mistake.

To me it's close enough to decide the "optimal" bet sizing based on our live read instead of just the numbers. Bet as much as we think he might call.

im check raising the flop, like you said, V has seen you playing a lot due to your hot streak, nows the time to check raise and see if he tries to get fancy. When someone check calls my flop bet on a board like this, I pretty much know for fact he has a hand. 9x is about as weak as you can be here.

As played turn, betting out vs checking is up to you, i would probably bet out, but checking is fine.

As played V ought to think he has near zero fold equity here, 9x+ is calling a river bet, and thats your range, so you should bet out, since i dont think you can induce. Once youve checked obviously you shove. although probably less likely he calls with your hollywooding.

Generally I prefer a 3bet or fold pre, but your reasoning for doing otherwise makes sense. If it's a mistake I don't think it's a huge one. Flop is ok. Turn is ok, but donking might a call based off your table image. Leading or checking River is also fine. Now that villain has overbet, his range is essentially a flush or air. Jam now, if he has a strong flush he will pay you off here every time, and even weaker flushes will have a hard time finding a fold. If he had air, he isn't calling anything anyway. A jam might lose some value to 9x or overpairs, but I think villain should have lead turn with those hands.

There is the very slim possibility that villain got sneaky with 88 or 99 and decided to let you try to make a flush, but basing any decision off that is MUBSY.

As far as flatting goes, why would we ever check if we intend to flat? Is it because we expect a PSB and are concerned by the overbet? To me, our check on the river means an overbet is the dream scenario. If we get coolered, then so be it. I'm never flatting.

You flopped trips and rivered a boat and after your river check, had managed to put a whopping $32 (7% of V's stack) into the pot. You, sir, have played it wrong. Don't care about the results at all. No sense in making a monster for 7% of a stack.

Preflop is a little loose, though I guess ok. We see how out of position you have difficulty extracting value (and likewise your ability to steal is blunted). I like the flop, as you'll be calling with many two pair hands and possibly a few other floats.

You could try a smallish donkbet on the turn as the range of hands that would do that is wide: could be two pair hands blocking, could be you picked up a backdoor draw, could be trips or better. Villain's most likely response is to fold or call.

We learn little from vil's turn check. If you have reads on turn tendencies, those would help.

Your line up to and on river looks like monster value extraction. Asking "how much you have" then raising all-in is likely to get looked up only by nut flush or better, while I can see nearly all overpair hands shrug-calling a minraise. So is 20% of $210 better than X% of $90? You can tell us what you think X is.
