[Guruman]

I'm not a NL Guru (hell I'm not a poker guru), but I think that most good NL players will only cc if they have a good read on a villain's range and can make the appropriate laydown on the flop. They also probably rely on being able to take free cards.

Openlimping is probably safer in NL than it is in limit, since a LRR often ends with the words "all in". Players may be more wary of this, and less inclined to raise for value with a top pair type pf hand like a couple of broadways. Small pairs probably don't raise vs openlimpers as much either, since they'd rather hit a set and try to get all in.

These type of questions are definately better answered in the NL forums though.
