Your ranges should vary depending on the villans (styles and tendencies). When you 3b or squeeze as a bluff is always nice to have blockers to strong hands, and that seems to be what you thought about when designing the ranges above. But good blocking hands, such as ATo, will be terrible hands to squeeze if you know your opponent will almost never 4b and is likely going to flat in position with a good portion of his range. Against this type of player (if you ever decide to squeeze against them, because I think you should always aim tighter players instead - but I know that you can't avoid this always) you should be looking to use hands that flop well and that you can continue barreling with equity in a good amount of boards. This can be accomplished with suited connected hands, such as T9s, JTs, etc. The main point about deciding wether to squeeze x cold call with certain holdings relies on your EV with each play. If you think you can make more money by calling, then you should call. The problem is that you are going to play a multi way pot and most of the time OOP, which is not the usual scenario from which money goes into your pockets. By squeezing you apply fold equity immediatly and you can bluff more often on certain boards because you will proably hit the flop HU instead of 3-way, which encourages you more to continue the aggression post-flop. Overall I think that on the first scenario you pointed, blockers are more important than anything...also you should have a read on UTG's range, because you don't want to isolate yourself against a very strong range. Be sure that he can be wide enough from that position so you can profitably squeeze there. Against a MP open and a late position flat, I think that the blockers lose some of their value, because those LP ranges will be wide and they are more likely to flat your squeeze. They are still important, but since the likelihood of you getting called is higher, you should add some hands that can flop more equity than ATo...suited (and off suit too) broadway/connected hands are good candidates, since some of them have blockers AND they flop very good equity.

I don't think we should be ALWAYS flatting suited hands like you may think...we should for sure do it some % of the time, but since we only flop a flush draw 10% of the time, we should definitely add some combos to our 3b and squeeze ranges

These ranges seem to be pretty advanced and probably good vs. very tough opponents since we have to worry about board coverage etc. Not sure if squeezing a hand like QJs make sense when playing smaller stakes(?)

I'm not very familiar with pokersnowie, how does the program come up with these ranges?

Do you know if snowie is squeezing/call4b with hands like KQs or 99 ? Or just shoving 99+ AK and folding the rest
Thx
