OK, you probably have learned from this thread that folding for one bet after you have limped is a bad idea. You'll still need to be careful. 3% is 40 hands. This is AA-JJ and AK, roughly. Since you have an A and a J, your opponent is about half as likely to have KK-JJ as AA or AK. This means that if you flop an A, you will win half the time. It's worth hanging around for the flop.

I see a lot of people saying that you should raise AJ in UTG as if it were some kind of gospel, and it just isn't so. It depends very much on the game. If it's soft (5-8 players/flop), definitely raise AJ, because you'll likely get called by worse hands for two bets, which is a huge win for you.

If it's tighter (2-4 players), raising AJ is probably a mistake (IIRC, SSHE recommends that you call, not raise). The reason is that in such games, raises discourage action, but calls encourage it. Limping increases the chance people will play even more than folding!

If you raise, on the other hand, people will call in such a game only with higher quality hands, and you are out of position. You want to invite the crap in order to increase your edge.

There is a problem with this approach in tough games. Some tough players will isolate a limper with a raise on a marginal hand. To adjust for this, you would need to develop an opening strategy that disguised the value of your hand. You usually don't have to worry about this in a small stakes game, but now that apparently 30-60 is small stakes on these forums, who knows?
