Preflop hands question

[bouh]

I wonder how weak is my preflop action. if someone raise 4BB before me and I have AQ (or AJ) I will fold it. Only way for me to call him is if I have AK, a PP or if many called the raise a suited connector. I Wonder if I AQ is a good hand to call a raise or not. I saw many people raising their middle PP or even KQ AJ in middle or early (on .5/1 table) and so I wonder if starting to call those raise with AQ (AJ or anything else) can be a good thing or I should skip to my standard (which aren't working good lately ;o ).
If I hold AK in Late position and someone raised 4BB I will call it and not raise it. Should I reraise more with AK ?

So I am curious to know what is your preflop action.
