I open to 8 pre flop from MP with J9 of clubs I get called by a really bad laggy rec. player in the cutoff and a super nit on the button.

The cutoff player bought in super short and sits on about 40 bucks the nit has about 200, I cover.

Pot is 23. Flop comes 7s 8s 10s.

I lead 15. Laggy shoves for 36 total. Nitty calls pretty quickly.

I've played quite a bit with the nit. He doesn't put money in the pot post flop without a big piece. I discount flopped sets and two pair because I think the nit would raise there some of the time, but he could flat with those hands.

I think the main part of his range is A10-AK with one big spade or else a big flopped flush -- because I think he would raise a small flopped flush

So I don't want him to draw to a cheap spade but if I raise small he probably calls with both his draws and flopped flushes. If I raise big I probably get him off the draw and he only continues with hands that beat me (or the occasional set)

Hero . . .

You already described the button as "super nit" who "doesn't put money in the pot post flop without a big piece". My gut says fold. One or both may have you beat here. But I can be MUBSY.

J9 wouldn't be in my MP raising range at 1/2nl. Especially with a LAG on my left. But if I had a reason to make this open (for example the LAG was extremely bad) I'd size my open larger: $10-$12ish. That said the best plan against this player is likely to limp/call his usual open and call down often when you catch a piece.

OTF I'm leading full pot+ here. Don't dick around with smaller bets when you flop a monster. The Nit's quick call almost alway indicates a draw. Would he at least think about raising with a set, 2P, flush, or straight. So when the action gets back to you if you call the pot will be ~$130 with effective stacks of ~$155. Therefore if you jam and get called its $155 to win $285 and you're getting 1.8-1 and need 37% equity. I'm sure a jam is fine here.
Also from V's perspective he's getting the same odds, which is almost enough to correctly call with a FD.

Lastly, your range for V isn't what I'd expect for a Nit. I'd either label this guy differently or go into more detail about his tendencies. And put those reads at the top of the thread, not mixed in with your analysis at the bottom.

Thanks. You are correct. I have played so long with these guys I have standard labels for almost everyone. But I have to remember to frequently reevaluate these perceptions and work to determine the critical tendencies that will allow us to really crush these players.

Further you have spotted that my estimated ranges are in conflict with my labeling. I suppose a better label would be "Player will call small bets pre flop with his high Ace hands and pocket pairs but tends to be very nitty post flop."

Anyways, I flatted the flop. The turn paired the 8 action is on hero with about 1 pot size bet behind. Hero . . .

C/Fold.

Are you thinking of turning your hand into a bluff?

No. I think he often has a lone big spade I want protection from. If I am raising the J9 pre I don't like folding straights.

Now with the possibility of a boat I don't think he's going to be very excited to put money in the pot with the bare As. I like a 35 bet/fold.

I would bet 45 on turn if he calls you c/f river. I suggest the small bet sizing because this type of player will possibly call this bet with his made hands as well as his big draws. If we bet too big here he will fold his draws and only call us with made hands.

If he raises we fold and if he calls we c/f any river. Normally I would not advocate this play but as described the nit probably doesn't have the balls to fire if he misses the river.

Betting 45 on turn gets us max value when we're ahead by keeping weaker hands in and allows us to get off cheap if he has us beat.

Villain read: super nit + doesn't put money in the pot post flop without a big piece

Flop:
Base on your ranges,
Hands that beat us: Flopped Flushes (which have us dead)
Hands that we beat: Sets 77/88/TT + offsuit AT-AK

So, looking at the hands that we beat, is ATo in super nit's preflop range? I think unlikely, which leaves us with AJo - AKo, and does super nit insta calling a bet and a raise with these? If so, will he be doing this with only Ks or Qs? insta calling with just overs and not drawing to the nuts? Which leaves us with AsJx, AsQx, AsKx, and again, do you think he calls quickly with these after a bet and raise?

Then there are sets, which I think are in nit V's range, because they'd like to wait for the board to pair before putting all the money in.

And is there JJ and QQ with a spade in nit's range here?

Super nit V's insta call leads me to think that he has a made hand, i.e. flush or a set, which we weren't sure OTF.

OTT, we cannot even beat sets now. When we check, nit V isn't gonna bluff us off with the hands we beat AsJx, AsQx, AsKx. Sure, we give a card for a spade, but given super nit's range is likely to have a crushed, we don't need to burn more money and just C/Fold.

Long story short, I don't think it is likely super nit has the range that we beat here AsJx, AsQx, AsKx alot with the insta call OTF. We can call flop, because we are ahead of flopped sets, if the board didn't pair OTT, I' bet/fold, but with this turn card, I want to get to showdown as cheap as possible.

Players like this will play their hands face up. So if your ranging of him is correct, call flop and then check turn. He is never betting with a worse hand.

I can't give the nit any credit for adjusting his play to mine but I had been c-betting a high majority of flops 3 handed and lag could be throwing his money in there with any piece of the board.

A10 probably isn't in his range pre. I guess he probably does fold the bare K spades, but I think he can and will continue with his As hands. I think he would 3bet pre with JJ QQ.

But you're right he has a nonexistent bluffing frequency when he misses a spade on the river so check/fold does seem good.

I just feel sick when I let it check through and he runs into a flush. It's a big pot and I don't want him to realize his equity here. I'm a big fan of bet-folding turn and I don't think 35 is any different than 50 so I'd make it the smaller side.

Maybe he just flats with a flush on that turn so I think we would always check/fold river.
