that is too advance for me, I may raise several limpers for value and to disguise my draw.

I dont raise this, but I think it's an interesting question.

I don't think we gain much fold equity by raising though. in other words, I think the flops I'm bluffing are ones I would bet regardless of whether or not I raised preflop in this situation.

Another thing to consider is that you don't want your hand range to be too narrow when you raise out of the BB in this situation. ie If i wanted to exapnd my range of raising hands in this situation, JTs type hands would probably be the best place to start.

Just some thoughts I guess.

Actually, I like a raise here. Hit any part of your hand on the flop, and your bet will get respected. Draws may call on the flop, but then you can take it down on the turn. Or if you hit your hand big, you can represent overcards, and your bet may get raised falling into your hands.
