I think AK is the hardest hand to play, especially when your confidence is so low.
I have been limping in early position with AK - something picked up by the 2 gods I sent the whole hand history of one of my recent MTT's - this IS a weakness and is caused by loosing with AK over and over again.
Richard, if confidence is really this low, get someone you respect to read over a whole tourney hand history - other than that,,, win a tourney - the confidence soon returns
