If you are new to VP (video poker) this is a great book to start with. Boyd keeps it real simple for the beginner and covers a lot of ground in 150 pages. If you've already read a few other video poker books like Dancer's or Paymar's you won't really find anything new in here. Although I did like her coverage of VLT's (Video Lottery Terminals).
The little bit of math that is covered in the book, has simple and easy to follow examples that a sixth grader could understand. And there are lots of clear and concise tables to help you understand the concepts on how to play smart VP, from learning the optimum strategies, to identifying good VP machines.
There's good coverage of the most common types of VP machines you will find in casinos. There is also a good explanation of ER (Expected Return), EV (Expected Value) and variance. Although ROR (Risk of Ruin) was mentioned, she didn't go into any depth on the subject, which surprises me because she covered everything else so well.
The tear-out strategy cards in the back of the book are a nice bonus. Because they would normally cost you about $5-$8 each if you had to buy them separately. The cards cover...9/6 Double Double Bonus Poker (98.98%), Pick'em Poker (99.95%), Full-Pay Deuces Wild (100.76%), 10/7 Double Bonus Poker (100.17%), 9/6 Jacks or Better (99.54%), 8/5 Bonus Poker (99.17%), 9/6 Bonus Poker Deluxe (99.64%), and Not-So-Ugly Deuces Wild (99.73%).
If you are serious about learning VP I would also get some good VP training software like...Video Poker for Winners, Wolf Video Poker, or WinPoker. You can now get the "Frugal Video Poker Software" for FREE, at Wolf Video Poker.
