For me, it's dependent upon how the limpers react to a raise. If they will limp, then give up their limp to aggression, raising is fine. Especially if there are player who will call that raise, then fold to cbets. Yum, lots of free dead money. Otherwise, if the situation isn't as favorable due to players defending limps too often, or not folding to cbets, then limping behind is okay I guess...sort of, in a real ugly way. Hmmm, yeah I don't like limping here so much.
Personally, I'd only be playing it if I can raise. I don't like weak aces, and I'd much rather have say, 96s or 53, something that can hit a real funky flop and possibly stack someone, also adding "WTF was he playing 96o?!???!" to opponent's thoughts. Always a nice touch.[/quote
It also depends how many bb bets you have in the tourney, you have 50 or more no problem with limping or raising. But less than that now your hoping you hit your hand and nobody else got some of that flop.
