Unless you have a specific read or playing a maniac then at this level a 3bet then call in position.
if your raised then up to you how to play it but generally micro players dont show that much strength unless they have it
out of position im flatting against most players remember your playing an A and a K.....
At this level so many players over value this hand your mostly playing against fish they have no concept of hand strength just two cards that look pretty and they will call with anything.....why put your stack in pre when you can see a flop and evaluate where you are.
Also as you already alluded to your getting called by premium hands pre ..... slow down and use your position
why get into either a 50/50 or dominated race when you have a clearer picture on the flop .....take it from me it took a long time to stop overvaluing AK.
hope helps
