Folding sb pf in a 2/3 blind structure?

[sternroolz]

This has probably been rehashed many times here, but I'm sick and can't read through tons of threads.

In a 2/3 chip structure blind($15-30), is there any hand I should lay down here pf w/ no raise and assuming a rational blind...hell, assume a passive fishy blind since that is what most of the players in these games are.

I've been playing every hand in my sb when BB is not raising a lot...anything...and raising quite a few more when there is only one limper. I can't imagine folding getting 8:1 3 way, 11:1 4 way, etc. Even with the horrible possition I'm finding that its not hard to buy a fair number of pots and only one player(out of like 100) has figured out that I'm getting totally out of line here. I think just the shot of hitting the winning hand justifies the call, but add in the chance of buying the pot, and it becomes a no brainer. But maybe I'm missing something?
