Background: I've been grinding 1/3 and 2/5 for a while, and I wanted to try moving up in stakes . This was my first attempt at playing 5/10.

5/10 NLH (1k-No Max). ~$1800 behind (I had bought in for $2k, which I quickly learned was a small stack at this table).

I was in the SB with Ad Kc. UTG+1 raises to $30, HJ 3-bets to $90, CO 4-bets to $400.

In this spot, I'm fairly certain you have to 5-bet jam (and my solver agrees). If this were a tournament, I'd do it in one second. But getting it all in preflop in a cash game seems nuts, there were two guys behind me, and yes, I have the roll to play. But I'm really not used to being in pots this big preflop. I ended up calling (which is much worse than folding) because I just couldn't bear to fold a hand I knew I should be jamming. UTG+1 folds, HJ calls. Flop is 7h 8h 10d, HJ checks, CO bets $800, and I have to fold.

(If it matters: UTG+1 is a whale, HJ is an OMC, and CO is a mid-high stakes pro; 5/10 is the lowest he plays, 25/50 is the highest).

I actually ended the session up by ~$500, but this hand just stuck in my head as just an incredibly stupid play.

I dont think we have to jam this facing this much action from early positions/this configuration. CO is cold 4 betting here, plus the OMC had 3 bet from early pos and is totally uncapped here as well.

If you are shottaking in particular, i think you can just fold this to be honest and its not a big deal at all.

Snap fold. I think I fold QQ in this spot as well. Jam KK+,AKs.

I find it hard to believe that this is a pure jam in GTO land. Is your solver output not mixing any folds with AKo here? Is your output taking into account the CO’s incredibly large sizing here at 4.5x?

I agree, just fold pre especially for someone taking a shot at 5/10 for the first time.

The OMC's 3bet from UTG+1 could even be enough to fold but adding in the pro, who should also know the OMC's range and still 4betting is even more of a reason to fold.

Fold this pre, no your not scared money for doing so. Calling is burning money though.

So fold pre, dont tell a soul.

I agree unless the players are pure spew maniacs this is a fold.

+1

Insta fold Pre. If he's really an OMC, this is heavily weighted AA, KK. And now you have a pro who says I don't have a problem with that range.

In some ways you should be thankful you had an easy fold on the flop, because you have a lot of RIO given you're hardly safe if an Ace, or especially a King comes on the flop.

So much this. If I had KK I'd hate life a lot more I think.

Yeah, in this spot I think folding KK is not as big a mistake as putting in any money with AK.

+1 to the fold pre camp. Whenever we see a solid player cold 4bet an OMC 3bet, we probably shouldn't be happy with anything other than AA/KK.

Honestly I’m not even happy with KK when I see that happen. Reminds me of a hand from a long time ago when I raised UTG with KK, I got min-3bet by an OMC and then an aggressive but thinking player cold 4bet the button. I laid it down, and the OMC (not the 4bettor) turned out to have AA.

This is why you need to fold. As someone upthread pointed out, you are against multiple strong and uncapped ranges, not just one. With AK, you need EVERYONE to not have AA/KK to feel good about continuing.

I find it very hard to believe that AKo is a 5bet jam 200BB deep vs two cold 3bet and 4bet GTO ranges let alone when one of the two ranges is an OMC range.

There is an argument to 5bet jam here as a bluff

Omc should be somewhat aware that whale has any 2 and probably will 3bet him with a looser range than normal, lets say 99+, AQ+

Pro knows omc is lighter than usual so he has a lot more 4bet bluffs than usual and his big sizing feels more bluffy too i guess.

We block AA, KK and should look pretty ***** strong when we rip this in unsuspecting pro’s face. Also hero has the scared money image so should look pretty credible. AK is probably the only bluff candidate i’d go with in this spot though.

In play i’d prolly just fold this and avoid the variance but jamming as a bluff is not super terrible imo, a lot better than cold calling.

He's not an OMC then. Perhaps blind vs. blind not in EP, but even then I'd say they'd flat most of that in the BB.

An omc doesnt care about position or bvb and all that stuff, but even the tighest omc will notice some whale thats raising every hand.
Also his 3x 3bet seems to be the weakest part of his range tbh, an omc usually sizes huge when he has AA or KK.

As a bluff it isn't nearly as bad as some people describe here. Qqs fold often enough here... Not a bad decision by any means to go all in.

You should really look up some stickies for the definition of what an OMC is, you seem to have a completely different read on them. They don't get aggressive just because they noticed a whale in the hand, and they do care about position and they don't 3bet light, or they're not an OMC.

Agree 100%. KK would be a total puke spot, I would not hesitate to fold this and not feel bad about it.

I’m curious if any of the hands went to showdown.

This is a trivial fold. You are taking a shot in a bigger game, have only $5 invested in this hand yet you are willing to basically risk an additional $1800 playing a guessing game OOP?
