On the button with two limpers I would raise 4bb+2. This leaves you with pocket pairs and should fire off an all infrom AA,KK,QQ and AK (you fold

-) (pp's are not so bad because you're a coin flop by river). The pf raise should remove hands like KT...
After the preflop raise post flop.. you have choices and it is player dependent. Don't get into post flop squabbles unless you know the guy (20 hands at least).
If a strong lead out bet is met by resistance ( you have after all got AK - well thats what he thinks) - then youre goosed.. stop betting
If your using a womens alias then it's a bluff....
