Thanks guys. AK is actually my most profitable hand so far according to PT and 2,000 hands.

What prompted me to post this question is that last night on a TV poker program, a viewer emailed in and asked for the "top mistakes that a beginner makes". The presenter, a poker pro and somebody who's name I did recognise but can't remember (so not just a presenting muppet who knows nothing about poker), listed this as one of his top 3;

"Do not overestimate AQ and AK. In low stake no limit cash games, these hands are overrated. If you miss the flop, all you have is ace high. You should only call with AQ and AK, maybe call a small raise, but never raise or reraise."

I was a little stunned...
