A British game researcher who has written the best books on card games I've ever seen. I highly recommend his books to anyone interested in learning the good games. Also, he alerted me to the fact that "Hoyle" is BS and that there are no "standard rules" to any card game (except maybe Contract Bridge), just a basic form and endless variations, good and bad. Aside from his extensive research and cataloguing of games, he has invented some good ones, too. Worthy of mention is Ninety-Nine, a three-handed trick game with an unusual bidding and scoring system. If you're a card player, check it out.
