Small blind - how do you play it?

If nobody has raised and the betting comes round to you, and you have nothing at all, will you always call the small blind to see the flop when the blinds are low?

I do - and wonder if this is a leak in my game? I play purely single table SNG and am talking about calling an extra 8 chips to take my 7SB up to the 15SB. If anybody raises, i get out, but if nobody has raised (just folds/calls), currently I will always through the extra 8 chips in just to take a look at the flop. It rarely hits, but obviously when it does you can make a killing because nobody expects you to match what's on the board.

Thoughts....?

Raise 4 or 5xBB with anything.

Raise 4 or 5xBB with anything.

Yes.
Otherwise dont just call with anyold crap imo. If both cards are suited then definatly see the flop. Same with unsuited connectors, gappers even two gappers like 10 7. imo dont call with j2 or other crap. You need plenty of help on the flop and that doesnt happen often enough to justify all the calls.
But if you like gambOOl or just plain aggression. Raise it 5bbs and be done.

In a SNG, I'm willing to take a shot in the small blind with almost any 2 if a few conditions are met:
-3 or more limpers
-It'll cost me less than about 1/20 of my stack to call
-BB isn't one of those players that can't stand to let people limp and will probably raise.

I think this is a very profitable play ... it doesn't hit often, but tends to hit big, and the risk is low.

I won't play hands that I am likely to question where I am at even if I hit twice. For example ... 34o. If I hit 2 pair, I am easily counterfeited and if an Ace comes, could easily be beat. If I get a straight draw, someone else could easily have the top end.
