Only raising preflop? Never limp?

[Joost1982]

I posted this apparently in the wrong section of this forum (<--- PL/NL Texas Hold'em, Micro Stakes), so here is my second try [img]/images/graemlins/smile.gif[/img] .

(1)Somewhere on this forum (I lost the direct link) I've red that on 25NL 6-handed you should raise every pair, Axs and every suited connector on the CO and the button. UTG you should tighten up and play only 22+, AQ+ and sometimes KQs. In middle position you should never openlimp, but always raise.

This leads to the fact that you seldom call, but almost always raise preflop? Is that right?

(2)I play 8-handed on CDPoker and on other sites I play fullring, how does this preflop raising strategy change for me then?

Maybe this is a stupid question, but I'm still learning...
