Short handed (5-6 players) I raise AJs and up from any position to 5BB. Sometimes even worse if table image allows it.
Precisly the reason i limp anything but AA KK QQ and JJ from utg in 6 max.
There might be only 6 ppl at the table but position is still so important.

I'll raise AK from any position. In EP i'll then cont bet at weak tight opps or check it if i miss against Loose/aggro opps. AK was my biggest losing hand at 50 NL but i'm up 1.2 BB/hand at 100NL. I got in so much trouble continuation betting and getting pot struck, now i can let it go and check the turn if i'm getting called down.
Two things here. First if i continuation bet its the same amount as when i have the goods. Simply makes me a little tougher to read post flop. So if someone comes over me i can fold if my AK missed no problem, say on a Q high flop. But, i tend to be able to buy enough pots with second best hands post flop of a raise simply becasue i come in the pot strong but always the same. A weak continuation bet would be an absolute tell that i dont have the best hand.
