QJ preflop

[TTChamp]

I would like to get everyone's opinion on playing QJs preflop on 2/4 and 3/6 tables at party. I typically have two strategies with this hand.

1. If I am a late position and there have already been 3 limpers I will limp as well.

2. If there is only one or two limpers I will raise PF and then try to steal the pot later (or take a free card on flop/turn.).

I have seen posts in this forum where some one will raise from late postion with these hands when there are as many as 4 limpers already in the pot. Am I missing something here? Should I be raising in these situations?

Also any thoughts on jts, qts, kjs in similar scenarios?

What about the unsuited versions of all of these hands?
