at these stakes 
TPTK is quite weak especially if you 
don't have any draws.  instead of worrying about whether you're driving opponents out, i try to play ak/aq as hands to 
trap villians at the table with.  many times, i think people feel attached to 
TPTK simply because they 
raise a significant amount preflop.  at these stakes, i would simply 
limp in with ak/aq from early and mid 
position.  if the table is incredibly 
loose and you find a bunch of limpers 
ahead when you're in 
late position, you should without a doubt 
raise.  however, most of the time it suffices to 
limp.  if you 
miss the flop and are without any great draws, it's an easy 
fold.  however, when you do hit your 
pair, read your opponents very carefully.  having not raised preflop, your likely to have better 
pot odds to be playing with.  in my experience, you 
push your monsters hard preflop, earn your money, and try to maintain it or grow it by hitting your draws or traps with all of the other hands.  it will definitely 
test your reading skills, but this will only make you a better player and one that won't fret when in these types of situation.
