100bb deep you can pretty much always 4b/stack off BUvSB with AK. You made it 3bb and he went to 9bb, so you can make this 23-25bb and call off even if he is only ever shoving with QQ+, AK. Here is why: If you made it 25bb for example and he shoved then there would be 126bb in the middle(BB: 1bb, your 4b: 25b and his shove: 100bb) and you would have to call 75bb. So 75/126+75=37.3% pot odds. Your Equity with AKs vs QQ+, AK is 41.9% so you have enough equity to call off profitably. Even if you only make it 22bb or 23bb on 4b you are still getting the odds to call. AKo is doing a fair bit worse and only has 38.82% equity vs same range, so the call off with a 25bb 4b becomes only slightly profitable and if you make the 4b smaller it gets more and more marginal, but I would still do it.

This all goes out the window if they only ever 5b KK+. You are obviously crushed in that spot, but you would have to have a fair amount of hands on someone or have really good table reads to assume in a late position battle like that, that people are not stacking off at min QQ+, AK.

The challenge in your spot is that you are 170bb deep. I wouldn't be 4b stacking off AKs that deep. I think you may still want to 4b, when you are deep and IP with a suited premium hand like this, but you for sure will get into some gross spots if they 5b or jam. I guess its not that gross if he jams. I would imagine that guys at this stake would never be jamming less than KK this deep, unless they are complete aggrotards. So I guess you can just easily fold if they jam.

As played I for sure would be calling the flop, even though it is a pot size bet. Not sure on turn, may still be a call. I think I would probably fold it too because I would be calling this 3b fairly wide, especially deep, so I think I would have a lot of other hands that can call a second barrel that have more equity than this hand that you have. The other thing is, I am pretty sure that when people start to push 200bb deep they don't 3b as wide as they do at 100bb, especially OOP. So I think you can fold on the turn pretty comfortably, unless the guy is pretty aggressive.

especially short - handed, happy 4 bet jamming! We will miss the flop most of the time and have to give it up when it will be the best hand a lot

I'd prefer getting the money in preflop for anything less than 200bb, we're only 4handed after all.

Unless villain is a bit of a maniac I'd probably fold the flop, even with a spade on board, just facing the threat of future bets is enough for me on a low board. We also have to contend with people playing 3bet or fold from SB which often includes small pocket pairs these days.

I'd fold to a pot sized bet because I don't like calling in the hope of hitting. All this backdoor stuff isn't for me at nl4 without serious information. I try to keep it simple and hit them hard for value when I have something better than two overs - and yes, I end up folding AK a lot postflop.
