As a general idea, I don't think that considerably altering your play to "trap" bad opponents is very good...in some ways, you're lowering to their level of play where another good, solid player can take advantage of you. Not to say that against certain opponents you can't open up some, but it's a slippery slope where you can find yourself making many mistakes if you aren't careful.

Seems like over and over I'll raise big (5BB or more, depending on how many chips are in the pile) early with KK or QQ, just to have 2 or 3 calls, including A7 guy who hits his A on the flop. Then I spend all my chips trying to convince him I have AK (which is dumb I know, if he called with A7, he's not folding it very often).

If you're against 1 opponent (or maybe 2 and 1 checked to you) you can continuation bet KK and QQ on an A high flop, but if you get called you're looking to show the hand down cheaply. You also need to get used to folding these hands postflop when it becomes clear you are against an A. Yeah it sucks, but just think of those times that you face three callers, undercards flop, and you end up taking down a nice pot.

Something to remember:

1. Poker is streaky, and there will be times that your KK does continuously run into an A on the flop. Keep it in perspective...long term it won't happen as often as it can in a short time.
2. We tend to remember times that we are screwed more than times we screw someone else. We don't think twice when our AT beats KK, but say "dammit, he beat my KK" when it happens to us. We view ourselves as really unlucky when 66 sets against our AA but just move on to the next hand when our lower pocket pair cracks AA. We tend to have selective memories when it comes to these things, so it's often not as bad as we remember it.

Also, as a general rule, you'll find better advice if you post specific hands using the guidelines in the FAQ. It's really hard to give meaningful feedback to a general post that encompasses so many situations and concepts.

Good luck.
