Actually this is not a bad book. I rather like the way Shulman breaks up his advice into "bite" sized tips. So the effect is reasonably readable, although if you are a reader of "Cardplayer" magazine you are probably familiar with the material.
I call attention to the so-called "reader" reviews in this section. Word usage fingerprint statistics make it very unlikely that more that 2 persons could have written the first five reviews. One claims that this book significantly improved his game. He writes this 2 days before the book was released!
Three of the "reviewers" have the same rather original thought. They point out that this book might improve your relationship with men in some way.
As of this date, none of the first five "reader reviewers" have ever given a rating to a book less than 5 stars. And four of these "independent reviewers" have also reviewed a book called "Trust" by Charles Epping. And guess what? They all gave it five stars.
This is not a bad book. But it would be exceptional for an honest reader-reviewer to give it five stars.
