Well, solver folds that hand. As you have AK suited. AJ/A9 suited is 4bet. I agree with solver, if you have A and K suits I would think about calling. As people in general don't fold, you need to hit something to win at showdown. I would like to see the flop, and as the pot is at least 3way the 3bettor shouldn't be too aggro on the flop so you should be able to get to the turn/river often unless someone hits the board.
Of course you CAN 4bet it, but solver assumes that original opener folds 80% and 3bettor folds 33% after him. Which is not true on that table. So the value of 4bet goes down, and even vs those FE's it's more or less marginal EV wise. So that's why I would just call. You have position, and if money goes in multiway preflop it's not a problem.
