I have just stepped up to $100 level this month and lost $375. I had 10,000 hands at 11 BB/100 when playing $50. A large amont of my losses have been in similar situations to the one described. AK, AQ have cost more $ than any other hands. I have learnt a lot from this thread and the links it contains. The key to the decision is the opening hands from the initial raiser, If he is a tight multi tabler at $100 his range might be only JJ+, AK in which case your only chance to make money is JJ and QQ even their you need a good flop, if you get a good flop he may fold.
In future i fold here.
