Raise/limp AK, AQ, AJ?

[swifttarrow]

I've had a lot of trouble playing AK, AQ, and AJ when I don't hit. Since most of the 3/6 live games have 5-6 players to the flop, what's the best strategy? I thought about raising preflop and checking on missed flops (both IP and OOP), or simply limping more in EP to encourage hands like ace rag to stay in. Obviously, if I flop a nut flush draw to go with my hand, I'll gladly cap the pot; however, when flops like 10 j 4 hit, I have the most trouble. Do I c-bet hoping to take a free turn card? Lean towards checking against aggressive opponents? How often should I call a turn bet with only overcards in multiway pots, and how much do I have to worry about being reversely dominted? (assuming I close the action)
