i dont mind flatting with reads in the 1st place, readless i 3bet here 95% of the time and the other 5% i prolly missclick or play to many tables to play good
that said the spot is awkward and 4bet shoving AK looks like a 66-99 which is FOS and wants to push someone of JJ or AK (which is never going to happen online).
vs a 3betting range of 99+ AQ we have about 45% Equity here if he is not folding anything to our wired line.
dead money in the pot + the chance that his range is wider i dont mind a 4bet shove here but i think the hand is missplayed preflop and 4bet shoving this is supoptimal.
