On the A2 vs KQ debate - I'm sorry Paxo, but I think you've missed the point slightly. There are two factors to consider when assessing a starting hand HU - hot-and-cold strength (which you talk about) and playability (which is what Jay is talking about). Which is more important depends on the depth of the stacks - if you both have stacks of 300BB, the chances are that you're not going to end up all-in preflop with either of these hands, so hot-and-cold goes out of the window and playability is all. If you both have stacks of 10BB, you almost certainly will, and having the Ace gives you a good chance of starting a race in the lead.

The hot-and-cold challenge you issue (cap all the streets, you have A2 he has KQ) is pretty irrelevant. H & C is most important if you're ending up all in preflop - not likely to happen in limit. And if you play no limit, it is very unlikely that you would want to be all-in preflop with A2, because you're likely behind even a loose opponent's pushing range (say any pair, any Ace, any two face cards). In fact, against that range, even a suited A2 will only win 41.1% of the time.

Jay - I agree with some of your conclusions, but I don't think your system is massively helpful in that everything it points to is fairly intuitive anyway. Anyone who has played a few thousand hands of HU will have a decent instinct about whether or not they need to worry about their kicker or not, and before that instinct is developed it is unlikely a point-count system will be helpful. In fact, in the long run it could be damaging, because it would inhibit the development of that instinct.

Second, I don't believe that kickers are as important in HU has they are in other forms of the game. For instance, in a vacuum, I would go to the wall with KT on a K84r flop - if I were to do that routinely even in a 6-max game, let alone full ring, I'd want my head examined.
