(1-2 game in casino, standard type of game, new player only played a few hands appears to be in his 30s)
Everyone folds to hero. Hero($420) opens MP+2 with JJ to $10. Everyone else folds to btn who RR to $30; he has about 70 behind.

Im stuck, i have no idea what the correct play here is. All my options seem blah.

Thoughts?

It's always the same.

1. Determine the BOTTOM of villain's range.
2. Determine your equity vs. villain's entire range.
3. Continue if you have a positive expectation.

E.g. if we believe villain will do this with a hand as weak as AT offsuit, then we are facing a range of top 11%. Since JJ has 59% equity against that range, of top 11%, this is an easy call or raise.

Whether we select the call option or raise option depends upon whether we believe villain plays better against one or the other option. Obviously we choose the option he plays poorly against.

For example, if we believe that villain will (correctly) fold AT offsuit, and the remainder of the bottom half of his range, if he misses the flop, then moving in PF is probably better.

Thats pretty much what I'm asking. Is anything worst than AQ(maybe even AK) RR me here. Probably not right?

For 50bb against an "average" 30yo player, I gii pre. If he looked nitty, I might fold.

I would call and GII on good flops.

Devil's advocate says most villains at 1/2 only reraise AA/KK. A smaller subset include QQ in the mix. An even smaller subset adds AK to the fray. And an even smaller brotherhood that I belong to will add all kinds of hands like KQ, KJ, AT, etc., but that is more read/villain dependent and seeks to capitalize on dead money.

Facing an unknown I generally just give them credit the first time around. What's going to happen if you call is he is going to shove any flop most likely, and any flop that you have an overpair you will probably talk yourself into calling, and then he'll flip over AA or KK.

As per last post, you believe my best play may be to fold? I tend to agree with this after giving it a think.

For the hand. I jammed, not wanting to call and decide. (I tend to play in very aggressive underground games and a shove would have been the correct play.) I got what seemed like a crying call. He turned over QQ

Given no read other than new player with smallish stack... I'd think you were close to 50% equity.... lots of AK, AQ, maybe AJ AT in his range. You've only got 10 in... so feels like a close spot. Shove if you feel gambly, fold if you don't.
Alternatively I could see a call here and bet a non AK.

How could you possibly make this statement about an unknown that we have played "a few hands" against? Pulling that fairy tale range out of thin air and pretending it matches reality is one of the most ridiculous statements I have read on 2+2 lately. It is certainly not a population read that applies to east coast 1/2.

Well, if you don't have any reads - you need to assign a range. You pick your fairy tale and I'll pick mine. I presume the OP was looking for opinions. I see many players in my game 3 bet with ranges like this.

And i've read many more ridiculous statements than this... in fact, I've noticed a correlation between hyperbolic, braying sentiments (like yours) and degree of ridiculousness.

this is why i think given a standard 3-bet range of a 1-2 player and this stack size i think folding may be my best play. Calling sucks and I can't be all that happy getting 50bb in here. I think my best play here is make an annoyed faced lay down and find a better spot. (which there are many at 1-2)

Assume the stacks are going in. You're risking 90 to win 110. You need to win about 45% of the time to break even. Villain's 3! range needs to be TT+/AQ+.

I doubt your typical 1/2 villain 3! with a range that broad. You should probably fold and assume an unknown 3! range is QQ+/AK until proven otherwise.

Did he look like a man beaten by jacks?

Raising 30 of a 100 stack as a 3x raise seems pretty strong to me, "in a vacuum"

If you think AJ suited is the bottom of his range, that's top 4.5% and you have 49% equity. Against a complete unknown, I probably wouldn't be willing to narrow his range much more than that.

You probably didn't make a big mistake by shoving, and you probably would not have made a big mistake by folding. You don't know what his range is from one hand.

Fold.

I'd consider going AI w/QQ+ you have a very trivial decision. No one 3-bet's light in these games. Either way if you go AI your flipping at best and why flip vs. a range that has you destroyed your going to run into the top of it almost always instead of AQ/AK.

Rounders eh?

I think it mostly depends on how long he intends to stay. If he looks like he came to camp out, then you are probably exactly right. (He probably doesn't want to rebuy after his third hand if he intends to stay a couple hours.)

In a vacuum you are never making a huge mistake by folding all but AA/KK to an unknowns 3-bet at 1-2. Especially when you are OOP. Readless I'm folding here.

I'm not necessarily disagreeing with this observation - but it's not true in games I play and I've got to feel that applying this advice would be tremendously exploitable.

Being exploitable at 1/2 is not a problem. The goal is to play exploitatavely because your opponents are being exploitable by, e.g., only 3betting QQ+. If that makes you exploitable that's fine

+1 nice.....

Yeah 1/2 players "vacuum" range is AA/KK/QQ/AK and your equity is no Bueno against that. So that's a fold.

Additionally if your playing 1/2, your post flop edge is probably ginormous so look to push that, not preflop coin flips if possible.
