[Good Friar]

This is primarily a limit idea, since actual pot size is far more important (given smaller implied odds). There was a pretty good article in the internet magazine a few months ago about this topic. It is certainly very useful in stud, and it comes up freuqently in posts in that forum. The small edges you are eeking out of your opponent's mistakes preflop are small bets, when they chase, the best can be larger, and they can make the mistakes on multiple rounds.
