Help me with AK here

I don't like how I played this, what should I have done? The turn and river bets were so small....I felt like I should call even though I was pretty sure I was beat.

In a 3way pot I dont know if I cbet this flop, again, there are 3 players and the texture isnt great at all and with a gutshot to the nuts, two overs and a backdoor nut flush draw you dont want to be pushed off your hand by a raise. Id check here and hope for a free turn and call a bet if I thought my immediate and implied odds were there. As played I would fold to the raise on the flop. The turn brings an ace, why are you check calling here? You bet the flop and called a raise, I really dont think you can check/call this, Id make a strong lead and fold to a raise. As played I dont mind the check/call on the river, I just dont like how you got there. And use a hand converter.

I probably wouldn't bet this flop, but if you do, let it go when you get raised. You don't know if your A's and K's are outs, plus no redraw to the flush, and you will be oop for the rest of the hand.
