Blind play

[Sinnerman]

Hello, im quite new on these boars (as a poster), and I have a lot of questions I seek answer to.

For the time being im focussing on Full Ring play, NL, micro stakes.
I am often uncertain what the right play is when I'm sitting in the SB/BB with reasonable hand. I think I will understand easiest by some examples.

For example, ~ 5-6-7 people limp, u are in SB with hands like QJ, KJ, KQ, AQ, etc.
Should I raise here? The problem is there is a reasonable chance i get called and I dont like playing those hands OOP.

Or another example, a raise and a call MP, LP. How do I handle those hands then?
Any advice on playing the blinds is much appreciated!
Thanks
