$2/$5 NL 76s in cutoff

I would just fold pre, but that's just me. If there were more people in the hand and we were closer to closing the action then I would call, but not if it's heads up vs an unknown (we rarely get good odds otf if we do flop a FD, and we don't know anything about his range or tendencies).

I would of bet less otf (~55), less ott, and I would check back the river as played.

I would check the river.

Technically, this hand may be 3! or fold preflop.

I’d rather 3bet pre

Ap, damn these are some big sizinggs, can i ask why?

His hand is an ace like almost always, if its our first hand i like a shove make it seem like we’re a maniac and get hero called.

Against an unknown, fold pre-flop.

Think I prefer to 3B pre.

Flop bet size seems way too big. I'd probably just bet 1/3 pot.

When we pot it on flop, I might just check back turn.

As played, just check back river, I think.

You need to get value. I don't like 1/3 pot flop or check turn. Pot/pot seems to big though. Check the flush completing river.

For all the player who wanna 3bet this pre, are we really 3betting this wide vs a total unknown MP opener?

I would probably fold, but 3! is better than call. I wouldn't be 3-betting every suited connector / gapper. Hand plays well 3!, as you can misrepresent big hand pre on A or K high flop or low flop.

Pretty much what others wrote. Fold pre (3bet better than call), smaller flop (glad this was called, but weird), smaller turn, check back river.

Never folding preflop this deep and in position.
Would 3bet fairly often, especially if we have a read that btn or the blinds are squeeze happy. Otherwise, calling seems ok, although not solver-approved.

Postflop, as all others have pointed out, your bet sizes are theoretically way too big.
However, I must say I do not really hate them: if there are two hands with which to take such a wild line, those are precisely the two remaining combos of 76s.

As played, against an unknown, I would be contempt with the value we have extracted and check back river, also because I am quite curious to see what V has.

Deepstack yes, defnitely.
SCs are a great hand to 3bet in position:
- we are happy to take down the pot if all fold;
- we have an easy fold if anyone 4bets;
- if we get called, we'll play IP and most likely HU postflop, which is the configuration in which SCs play better;

Checking and calling two streets looks like either AA, a flush draw like KQs, or something like AK-AJ trying to get to showdown in a WA/WB situation.

Since you are new to the table, villain will probably fold the weaker hands to a river shove, leaving what seems like more hands that beat you if they call. That's just a population read: give you credit until further evidence to the contrary.
So I think there's some value in a small river bet but it'd be hard to fold to a c/r once you have over half your stack in.

A side note, "UTG+4" was a bit harder to process than saying either LJ (if 10 handed) or HJ (if 9).

This feels pretty spewy against an unknown...shot

...and chaser.

Do people normally consider 200BB a "deep stack"?

For those advocating 3 bets against an unknown, I'm curious if you have any calling range.

Really? I would think its the opposite , some new guy just sits down and starts betting pot on every street first hand, just seems sus, im not saying i would call a river shove but some random 2/5 rec might just look him up with an ace there thinking hero is crazy.

I would flat call with some stronger hands than 76s. I would call more than 3!. Not a linear 3! range. 76s is not strong enough to call with IMO, but could sometimes be a 3! representing a strong hand with deception. You can bluff with 7-high, semi-bluff with a draw, or hit on a flop like this in ways that are hard to read. It has better playability than a small pp or even Axs. I would sometimes 3!, sometimes fold, some hands not strong enough to flat call with, as well as big hands and sometimes 3! something call with like suited broadway.

Personally, I consider 200x effective already fairly deep. Very few guys in my pool play deeper than that on a regular basis.

All of the 2/5 games in the northeast have a buyin of 200 BB's, which most people do buy in for and it's not uncommon for many players to be 600 BB's+ deep.

Something like this.

Mostly call: small to medium pp, medium AXs, some off-suited broadways, 89s.
May fold some of the above if the OR is very tight or short stacked, or if we have one or more aggressive players behind us.

Mix 3bet and call, but mostly 3bet: small AXs, SCs (45 to 78) and suited broadways.

I my experience, people 3bet/squeeze WAY less than a solver would do, which makes it OKish to call pre with a bit of a wider range (actually to have a calling range at all).

Since you apparently play in a nitty 2-5 player pool, where people don't 3! light, you may be able to get away with coldcalling more often PF, but you should be aware that most 2-5 games aren't this nitty.

Almost none of the people responding posted a modicum of reasoning behind their answers. To those suggesting to fold pre: Why? To those suggesting to bet smaller on flop or turn: Why? To those suggesting to check back river: Why? Just stating what you would do with no reasoning whatsoever and no support for why it's done is pointless.
In OP's position, I would always 3-bet this hand preflop, not fold. Why? Because any given random person I haven't seen before has a probability close to 100% of being a fish. Why would I want to miss an opportunity to isolate a fish and either win the pot outright preflop or have an incredibly high chance to play postflop in position against an opponent who is almost certainly not 4betting remotely frequently enough?
On the flop, the sizing seems completely fine. You are targeting an ace or a flush draw and have 3 opponents. The odds that one of them has an ace or a flush draw is high. Loose passive fish love to call with random raggy ace hands as well as random suited hands. If somebody put a gun to your head and told you that you had to make a loose passive fish fold a random ace or flush draw here, would you bet only $75? I sure wouldn't. If not, why are you betting small? I think even a larger size could work, even something around $100 for a small overbet.
On the turn, for the same reason as on the flop, I think an overbet is still better here for the same reason, but the size used is totally fine.
On the river, after our hand is downgraded, I still would try to go for value vs. an ace. Do I think a fish would crying call an ace for just $200 more into a pot of $670? Absolutely. Do I think a fish is bluff jamming in this spot? Almost never. Do I think a fish is value jamming an ace on this river? Not likely. Maybe AQ exactly. Therefore, I'm completely fine with betting around $200 on the river and finding an easy fold facing a raise.

I think check the river. We are struggling to get called by worse, esp after we choose this size on flop and turn.

Pre I lean towards fold. Low freq 3b or fold if raked, low frequency 3b/call/fold if unraked. Esp because of the 4x size.
