Preflop
You can size up a little with your 3-bet. When he 4-bet, I like, that you just called. Mindlessly stacking off AK preflop in a 100BB cash game is usually a good way of setting money on fire. Although to be fair this is 6-max, where players are more loose and aggressive in general. But you do have position in this hand, so I like to just call and see a flop.
Flop
Obviously a good flop for you, but before we start to plan the hand, we need to think about, what a open UTG and then 4-bet range looks like. And its typically something pretty snug like TT+, AK at the widest and KK+ at the narrowest. Maybe with a few bluffs thrown in like A5s, KQs, KJs etc. Typically its not a lot of AQ or AJ, since these hand would just call your 3-bet or for AJo even fold.
So even though you likely have the best hand a lot, especially when he check to you, there are not a lot of worse
hands in his range, that are going to be willing to stack off. You are trying to get paid by JJ-KK or hands like A5s, and for that reason you need to go small and give him a price, where he just dont want to fold. Something like 25-30% pot rather than half pot.
This is also due to pot geometry, because if he call half pot, you will only have around a pot sized bet left, which is awkward on the turn. Because then you can either jam for full pot, which will get a lot of folds, or bet much smaller, than you did on the flop. If you go small on the flop, you can make it a 3 street hand with consistent bet sizing, and this is definitely the way to go, when you have nothing to protect from, and you are in position.
Turn
This is not the best card, because you now lose to JJ and also AJ and KQ, if he somehow have those hands. You also picked up a gutshot to broadway, and especially after betting so big on the flop, I think, this is a mandatory check back and then make a decision on the river depending on the river card and his action.
As played you have committed yourself to the pot, so you cant bet-fold. Its 1.32 to win 8.76, so you only need to win 1 in 6-7 times. And while he is probably never
bluffing or showing anything worse for value, he could have the same hand. Unless he has exactly KQ, which I think is kind of unlikely, you also have at least 4 outs to suck out on him, so at least you are not drawing dead.
Results
The hand is a pretty massive cooler, but its important to think about, what you are trying to get paid by, and to not accidentally commit yourself to pot with your bet sizing.
