Preflop
Not all the action is shown, but given the stack size on the flop you presumably 3-bet AKs and got called, which is of course very standard.
Flop
He is jamming $8.78 into a pot of just $2.25, and considering the rake you probably need around 45%
equity to break even. While you do have that against a hand like 99, you dont have it, if he flopped two pair or better. So while its not a significant mistake to call, given that you always have significant equity from your flushdraw, it might be a slightly losing call in the long run.
It does depend on his range though, and if there is any chance, he is ever doing this with a worse hand than AK, then you have to call. Like maybe he could have a worse draw and play it like this. Overall its a close to neutral EV high variance spot though, and it wont make a big difference in the long run, if you call or fold. Its also a spot, that wont come up very often, so its better to focus your energy on analysing other more common situations, where more significant value is won or lost.
