My turn raise is probably bad, but with his turn sizing i was confident (in game) im ahread most of the time.

River is prob bad as well. Not sure whats best...

dont really get logic of calling flop and then cr turn, we look super strong this way and only polarize villain range, once you get called on turn, on river you have bluffcatcher, with more dynamics you can valuebet river, but even then its marginal and propably a bit too loose vs uncapped range and unk villiain

we may be ahead of his betting range on the turn, but not necessarily ahead of his range which continues vs a raise.

I'd value raise pre most of the time.
You opt for a turn raise on a blank which only adds wheel draws, and those aren't as often in your range for peeling the flop out of position. You're representing an overpair or better as you probably wouldn't often do this with the flush draw. The problem is you should be 3betting most overpairs, so you should be weighted towards the trips and sets and air. You're more polarized than he his here.

That's why betting small on the river doesn't make much sense. What are you getting value from? A high busted draw or bluff catching weak pairs? Best case scenario is one hand. TT.

There are much simpler ways of getting money into this pot when you're ahead so that you're not faced with this situation. If you get the money in earlier in the hand, you're less likely to face big bets on later streets where you're most often behind plus creating good spots for them to bluff.

Although this a good spot to bluff, it's far more likely to be a value jam even with the unlikely 8 or better on a dry board with a busted flop flush draw.

calling JJ pre vs unknown reg is fine, but for reason you didnt 3bet you should play more str8forward postflop, and this not include turning overpair into bluff, btw even 3betting not make hand play easier, as good villain may not 4bet qq vs more polar range ip... but its another story

i 3b this pre more often than not but you should definitely flat it some % of the time so pre is fine. when you do flat you're underrepped, and since your hand also benefits from protection, i would raise flop vs his c-bet sizing (can flat vs bigger sizings). if you do decide to flat flop definitely just x/c turn also

Hey, buddy.

My 2 cents:

Pre flop: fine, but you should 3bet in some frequency as well.
Flop: this is very interesting, because we actually have a leading range here OTF. We want to lead a lot! But as played, this is a x/c 25% and x/r 75%.
Turn: as played OTF, this is a pure call OTT.

Best regards.

Hey pal,

My 1 dollar:
Preflop: 3bet this 100% if unknown, call some if you know its a good regular.
Flop: Against uknown player you should check raise here a lot given your holding. No player will call craiseflop, turn bet and then value bet an overpair on the river vs you bluffcatching (on this stake).
Turn: Now that you called the flop, lets bluffcatch instead of narrowing his range OTT or folding out all worse hands + semibluffs. What are you trying to get value from? TT/99 is proabably the only hands calling turn we're beating except for two overs and a fd which gets to play an easy river IP anyway super deep.
River: Given the huge mega raise on the river its an obvious fold. There is 100% not a single regular calling a checkraise on turn and raising a river bet on any lowstake under 100nl.
