15/30, waiting until the turn to raise?

[TheGrinder]

I decided to wait until the turn to raise with my 2 pair hand below. The reasoning was that there are probably at least a flush draw and possibly AK against me based on pf action. While I still have pot equity edge on the flop, it will be much bigger if a safe card falls on the turn. Then I can raise on the fourth street when bets have doubled. I can also hide my hand and get better implied odds by just calling the flop because someone will almost always bet to me on the turn when I have shown no strength. Then if a spade falls on the turn and the action gets heavy in front of me I can fold. Does this make any sense or should I just raise and jam the pot on the flop if a flush draw or AK 3-bets?
