When is the best time to utilize a stop and go?

[Inevitable]

I realize that a stop and go is done when someone calls or cold-calls a bet on the flop intending to bet, raise or push on the next street. When is the best time to utilize this in a full ring NL cash game? Could someone give me an example hand, one made up or from one they've seen or played? Thanks in advance.

You should post this in ssnl really, here (http://forumserver.twoplustwo.com/showflat.php?Cat=&Board=ssplnlpoker&Number=3300529 ) is one example.
