I've read the preflop strategy article('s) in the poker strategy section(The one with groups 0-7 of starting hands). Actually, that was the first article I read on here. Which helped GREATLY considering I had NO direction at all originally. Now I'm reading it again for the second time, and I thought I would find out some of the profitable players view on it.

My question is how much validity should I give it. Particularly at micro stakes. Should I play tighter than the auther?(Since they describe how they play) Or what? Any sound input is appreciated.
