But since we are out of position wouldn't our opponents be most likely to call?
I think 4-bet frequency isn't really as much of an issue at these stakes since they will have position on us and are more likely to call or at least that's what I've been seeing a lot of the past month or two since I've been back.
I could definitely be wrong here but I'd like your take on it. TBH I don't even have 4b frequency as a stat or ever check it since anyone who 4 bets me a lot stands out like a sore thumb...I might need to start doing that.
Don't get me wrong...I've definitely been seeing some of the higher limit players videos such as Ansky's talk about shoving their mid pair's (66, 77 etc.) to squeezes from aggro players but I haven't seen this much with players at 1/2 and below. On the other hand, I've seen an absurd amount of calling. This is on stars btw so it might vary a little from site to site.
So your read in your games is that mostly unknown regulars will call a lot of 3-bets in position and not 4-bet a lot. Then without information it makes sense to be 3-betting. If you happen to have stats and a large sample on some or all of the players, I'd definitely take a look and see if they 4-bet a lot before 3-betting. You don't need it on your HUD but it's default on the HEM popup so I'd recommend getting used to it.
Let's flip the situation around and make us the PFR. We open in the CO, BTN calls, SB who might be a fish calls, and BB who is an aggro regular squeezes 200bb deep. I like this as a 4-bet bluffing spot for us. First off, BB's range for squeezing is likely fairly wide. I think lots of people don't like calling 4 ways with hands like AQo, AJo, KQo, KJo, KTo, QJo, so I'd expect those to squeeze often. Secondly, there is lots of dead money. Finally, if we do 4-bet, we're leveraging our entire stack vs. the BB. For the most part, he's either 5-betting and committing 200bb or he's folding. The only hands that can really feel totally comfortable 5-betting without history/reads are AK, AA-QQ. The rest of his squeezing hands probably fold. Even JJ, TT, AQ, AJs are in a crappy spot. Put together the dead money, a reasonably wide 3-bet range, and a narrow 5-bet all-in range, and you have a recipe for a profitable 4-bet bluffing spot.
That's why I'm hesitant to just auto 3-bet KQs here. If villain is aggressive preflop he might see the situation similarly to how I am seeing it. Your read is that this is rare in your games. I buy that and you can go ahead and 3-bet. I just wanted you to know exactly why I fear a 4-bet here and why I'd usually check for villain's 4-bet frequency before I squeeze.
