Yup, that's the best way to get them to open up.
If you have raised every single hand for 2 rounds and you still pick up the blinds from UTG open another table and keep this one just to play crap for set, straight and flush value. If one of those guys suddenly raises 8BB, and both of you are deep enough I'd call him with a very wide range and hope to outflop him. He's not going to fold a hand he waited 20 rounds for just because the flop is 5s6s7s.
Probably not.
I often wonder what these guys look like. How can you possibly have fun playing über-tight online?
