In some spots you have to open jam tight because of ICM, and so people call you off tight because they need a good hand to have the right equity vs your range.


But if the players to act play these ranges because they assume you are a reg following ICM, it becomes profitable to jam wider and get good steal equity, and it’s only a problem if they knew your range changed.

So couldn’t you do this against people until they see your showdowns enough?

The simple way to think about ICM spots like the one you mentioned is, they know you're most likelly wide as hell, they just can't do anything about it, ICM doesn't allow
people to call their stack off (or a big portion of it) when there is shorter stacks, or a colision will cripple your future game prospects in the tournament, that said, there's regulars
that will call you off because they're going for the win and getting the double is more valueble than risking going bust. That mindset is very rare these days.


So yeah, you can just keep jamming garbage when the spot dictates you should, and when they have a hand, they'll call, that's it.

Its only profitable to jam wider than the NASH equilibrium, if you have an individual read or at least a population read, that people are not calling as wide, as they should. Such spots do excist, but they will not be common, if your NASH jamming range is narrow. In that situation people might actually put you on a wider range, than you have, and call to wide as a result. So spots, where people are likely to be overfolding, are actually the complete opposite. If your NASH jamming range is 80% of hands, and people assume something more like a standard 40% opening range, then they might overfold, and you could adjust by jamming any two. Such a situation could be blind vs. blind, when stacks are very short, and you cover. Then a lot of players dont want to go broke with a hand, that for them is not pretty enough to go all-in with, and they fail to adjust enough for both their pot odds and the fact, your range is extremely wide.

I will say though, that there are probably more spots, where less skilled opponents will tend to call to wide, and then the adjustment is to jam a tigher range. If for instance you jam UTG on a final table or on a SnG bubble, then in some situations players behind can be supposed to fold AQ or even AK, but a lot of people wont be able to do that. So when you are looking at push-fold situations in a program like ICMizer, you definitely also want to identify situations, where people are probably calling wider, than they are supposed to. And in that case you need to fold the most marginal jamming hands. Or maybe minraise if stacks are deep enough and opponents passive.

I think you misunderstood the question, perhaps I explained it badly

Its not only about seeing your showdowns. Its also about the % of time you are doing it when it folds to you in late position. Its true that you could have strong hands a lot and you are playing tight. But it is more likely that if you are shoving 80% of the time in these situations that you are doing it wide.

Still my experience in live games is that people call tight when you shove. This is why I shoved with 44 in the CO in the WSOP Main this year with 21 BB's on Day 3. The SB jammed for like 60 bb's with AJo and I held. I was very surprised the SB jammed with AJo (I was fairly certain he had TT+/AK). I was thinking that SB would have folded AQ to an OMC like myself who hadn't jammed yet.

Because I turned over 44 that was it on my jamming light.

Yes perhaps. Your initial post begin with the statement "in some spots you have to open jam tight because of ICM". And this statement dont make a ton of sense, because when there is high ICM pressure, what mostly get tighter are calling ranges, because the gap between jamming and calling ranges widen. But lets ignore this and continue with the statement "So couldn’t you do this against people until they see your showdowns enough?". And here I think, the answer is no. If you are in there ramming and jamming all the time, then people will pick up on that pretty fast and put you on a wider range even without seeing any of your hands at showdown.

Actually this is something, I often consider in situations, when I have the chip lead on an SnG bubble or an MTT final table and am "allowed" to jam very wide from any seat of the table. I dont want to create a situation, where this tilt people, and where someone might end up spite calling me with hands, they should have folded. So I typically make an effort to not take on every single spot with the most marginal hands and instead sometimes just fold and let the shorter stacks try to bust each other to not be percieved as an out of line "chip bully".
