C-betting in NL10.

[Cody1982]

I ‘m in need of some guidance as far as the art of the C-Bet. If possible could you give two reply’s one for early-mid (I’m raising PF with solid values from early-mid position) and late position ( I loosen my starting values and blind steal a lot when the pot is unopened)

Are there specific times when you should or should not C-bet ?
How much does position play a part in the decision to C-Bet ?
Should I only try to C-Bet 2 or less opponents ?
