This is one aspect of my NLHE game that I'm not too clear on, so In general, what hands should you call or raise from the SB and BB with in different situations in a NL ring game?

-1-2 limpers
-few limpers
-5+ limpers
-Heads up against other blind
-Heads up against raise from button or cutoff (assuming you don't know how frequently this player attempts to steal the blinds)
-Raised pot w/ some limpers yet to act
-Raised pot w/ some callers
-Raised and reraised pot
