Clear, well-written instructions and numerous illustrations of card hands. Basic rules and scoring systems, customs, methods of play. For the experienced player, Fry discusses odds, percentage play, discarding, forcing a draw, "advertising," taking cards "on spec," and much more.
Gin Rummy is my game of choice. We always played it growing up, and it was something I learned from my mother. I wanted to brush up on my knowledge of the game though since we mostly played straight as kids. While I am more or less comfortable with Oklahoma this book really helped to iron out some good game-play tactics, tips, and tricks for winning a hand.
The book could be a little dry in parts, and I think I am better at learning through doing rather than reading, but I am definitely excited to integrate some of these plays in my next game.
