Small Blind Play

In suitations where 3 or 4 players limp in to the blinds.....what hands should you call on the small blind?

I know you should raise AA, KK, AK, QQ, JJ, TT, probably AQ

But what should you call...I figure the next level of hands...KQ, KJ, KT, QJ, QT, JT, T9s, 98s, 87s, Axs

What about unsuited connectors? Lower connectors, 1 gappers, Kxs, Ax, Kx, Qxs, Qx...etc...

You don't have much into the hand if the big blind doesn't raise and the pot odds are strong...but you are up against alot of hands with a weak hand....Which should you absolutely just throw away...and which are keepers? Any math to your conclusion as well? Thanks

There was just a big thread about this same topic, check the search next time. Anyways though, heres the link to that:
