In 2000, I happened to join advising a Bridge Lesson Room in Yahoo! Bridge for starters as well as possibly "sophomores", almost every Saturday (later, every Wednesday as well), which continued about five years.
The deal, play, and score were automatically recorded through my own-made Windows software MiniHand, which enabled every parti-cipant to enjoy post-mortem immediately after each deal has been played. As often occurs among Bridge players, the postmortem tended to take more pleasant time than bidding and card play.
The resulting records have now amounted to a tremendous number, from which I have come to prepare a quiz-formatted Excercise Bidding in Bridge in 48 pages below.
