I also prefer flatting.

As played, I like flop check, we are not getting mulitple street from this hand, so might as well let him try and bluff it.

Turn is standard.

OTR, I doubt he is ever bluffing here, and I dont think he has worse 2pr, so a very tight fold I guess.

He defends 33% how does often he plays 4 bet?
If he call 33%, then your 3bet is 3bet on the value and with this range that he has to do.
what his fold to cbet?
because he has many Kx hands worse and you can play cbet on the flop, because he should call with bckdr. You can bet 2 street.

Or if you want you may x/b.

I dont think that he can bluff with 99 88 TT, I would have expected from him with these hands he likely to fold or call.

IMO I don't prefer flatting preflop. By raising you can define his range while just flatting, its his entire range if he just intended to steal.

I'd rather bet the flop then the turn just because most of the v range is going to call you and by you checking behind you are giving him a free card. You might as well choose to raise flop or raise turn. I don't think your hands really strong enough to raise both streets

It's not really a draw heavy board so I think his hands polarised on the river.
It's a hard fold but it's likely he has you crushed. It's a close tough spot on the river. I would probably end up calling and be crushed a big % of the time with 66

The 3bet is fine. I prefer it to flatting, especially vs a guy stealing 83% from the SB.

I'd probably bet the flop, but checking back is OK too.

Turn bet is fine.

River is obviously a value bet, and i don't know what its like at these stakes, but i could never fold KJ here to anyone that isn't a complete nit. Its just way too exploitable. If you don't call KJ, your calling range is 66 which isn't wide enough.

You cap your range on the flop, and i fully expect people to attack this. I know i'd definitely xR the river as a bluff relatively often in villains situation.

Maybe at 10NL no one is picking up on the fact that your range is capped, but if villain is at all competant i'd be snapping this off.

Edit: You are also getting a really good price. He really doesn't have to be bluffing often at all to make this a call. There's also a small possibility that he does this for thin value with 67s.

I prefer 3betting preflop to flatting.
Unless you have specific reads on the villain, I don't think you can fold top two pair on this runout.
