play around with pokerstove or propokertools so you can a feel for the equity of certain hands vs. various ranges.
Because unpaired hands are so much more common than high pairs, you're usually not in as bad a shape as you might think if you hold a pair.
i.e., if you put someone one AA-JJ, AK (which is a sick, tight range) and you have QQ, assuming you have money already invested you have 47% equity vs. that range, unless you have specific information to believe you are beat, you shouldn't fold.
Likewise, you may feel that you are only flipping at best with AK, but because of card removal (there are fewer combos of AA/KK possible when you have AK than when you have QQ), you are still in good shape against that range, about the same as QQ (40%).
It is important (I think) to note the difference between AK and AQ vs. the top of people's ranges....if you can include AQ in someone's range (AA-JJ, AQ+), AK becomes a small favorite against that range.
AQ vs. the same range is a big underdog (34%).
