Villain in this hand is a ~40 year old Jewish guy playing a very active game. Been playing with him for about 5 or 6 orbits and have no history on him. He's opening a lot of pots, especially in late position. He's also calling a lot of preflop raises and he's over-calling/chasing draws post flop (only to a point though, if someone bets big enough on the turn for example he'll give it up). It's important to note that he hasn't done anything overly aggressive as of yet. He hasn't put in a big raise post flop, hasn't 3 barrel bluffed anybody, and hasn't made a 3bet preflop. Only got caught bluffing otr once in a smallish pot.

Hero is in his early 20's and has a standard TAG image to this villain, haven't played any hand of much significance since he sat down.

9 handed game

Villain has ~$550 and hero covers.

2 limpers.
Villain is on the button and raises to $25
Hero is in the SB with XX and raises to $85
It gets folded around to villain who instantly makes it $300

Is this a spot where he has QQ+ or maybe even KK+ every time? Could he be doing this with AK? Could he be doing this with worse than QQ or AK? His range is wide when he makes the original button raise, but the bothersome thing was how quickly he 4bet to $300. Although this villain is loose he has yet to make a move this aggressive as of yet. But then again, I don't think anybody has 3bet him yet either.

Obviously it's shove or fold time for our hand, what hands do you guys think we need to continue in this spot?

Thanks!

Key caveat below: given that this is a live game vs a loppy opponent (lop = loose and passive)
Without better reads, I'm pitching AQ- And JJ- w.o much thought.
You're too short to not go broke with KK (all-in)
I'm probably pitching AK, given that I think you're never ahead. At the very best you're flipping with AK. More likely he's at JJ+. I need more specific reads or history to know that a guy will go AIpf with AQs (or less) in a live poker game.
QQ is 60/40 jam/fold.... Against a guy like this, I might fold figuring I'll have better spots against him later. If I think he views me as a young gun and would ever go for a level, this is an auto-jam

Passive guy that hasn't made a big bet in 5 - 6 orbits.

I think this is 90% AA and 10% KK.

Since "he hasn't done anything overly aggressive as of yet" and you have a "standard TAG" image, I'd say he likely has KK+. He has put in > 1/2 eff stack, so I'd fold QQ-.

I'd fold QQ too for reasons already stated.

Could he have AK/QQ? Sure, he could, isn't likely but he could.

Given your description the only thing I'm happy to play is AA. QQ and worse gets chucked fast. KK is the debatable case, depending on my read of the situation I might fold or I might shove. Given your description, I lean fold but he sounds just loose and aggressive enough that it would be hard at the table.

His range is probably QQ+, AK.

I would shove KK+ and fold everything else.

5-6 orbits is 50ish hands (rarely is everyone at a table)

You get KK or AA about what, 1/180?
Very easy to go 5-6 orbits without having something worth betting; with ALOT more history, I'd agree with your range. That is the same for the type. However, this guy is loose enough to give me a bit of pause; i'm unclear that he isn't good, yet.

I agree with the consider folding QQ idea (as I said, 60/40 jam/fold that specific hand). But I hold we have nowhere near enough history/info to specifically range him as a passive drooler (which is a definite opponent type and would make your range correct).

I realize this is nitpicky, but I do think its useful for people to consider that we don't know enough and our live sample sizes are LOLsmall.
