Twizzy, you need to stop making bets that leave you with a tiny, ineffective stack in front for the rest of the hand.
Re: the topic, of course there are situations where it's a smart play depending on the table itself and the table's perception of you. If you've limped from EP with marginal hands before (let's not question the wiseness of this and just say that you have), and if some of the people left to act are very aggressive, it may be smart.
That said I will only limp to mix up my game, and this is the only way I regard it as +EV in the long run. Limp/reraising pretty much defines your hand as a monster, perhaps even more so than 3-betting preflop (and thus you're less likely to get action against decent opponents without them having good implied odds
). One thing is for sure, if you do limp with AA/KK, you must be prepared to lay it down when things turn bad (e.g. you limp with AA, flop 7h8h9c, two people get into a raising war).
In most low limit games, people aren't paying any real attention to you though, so I think I'd pretty much always standard raise preflop.
