The bottom line here is, in ring games just don't do it. The vast majority of online players are very weak players...and those are the types of players you just don't want to bluff...they'll play any two cards at any time for any amount...those are the players you want to have a hand against so you can bust them.

Now, in tournaments, sure, you can pick a few spots and bluff. But it's just not worth it.

Most pros will tell you the same...against weak players to typically need the gods...

I can only think of a few very rare cases where I'll bluff at low stakes(.25/.50 NL-2/4 NL).
