22 might technically be ahead of AKs but which is more likely to take it down on the flop in a 3bet pot?
At these stakes, people call too much to pf 3bets and fold to too many cbets. If you're not going to exploit this tendency with AKs, then you're going to be folding it a lot more than needs be. AQ rarely folds to the 3bet, even AJ and worse is calling a decent amount of the time.
3bet for value and 100% cbet.
