raising for information..

[Joe826]

Sklansky says this is something that should be used sparingly. What do you all think? I find myself wanting to raise for information all the time. If I have a PP and there is one overcard out there i'll often times raise and fold to a 3-bet. The problem with this approach is often times the original bettor will get spooked and check/call to the river, in which case you've just given away a bet of some size if he has the TP as opposed to calling him down. Where do you guys use this sort of play? Is there anything way to avoid the problem i'm having in my example? Thanks.
