I had a stupid friend who thought bought this "book" from that site. It's horrible. His great cheating methods are:
1. Setting up multiple accounts on different IP's and playing at the same table.
2. Crappy psychology advice, that he claims can force people to fold strong hands.
3. Using poker bots.
And my personal favorite
4. Using TightVNC to see other peoples desktops. Which he says is very easy. He then goes on to explain that you will need to get the person to be running the 'TightVNC' server, then get their IP address and finally get their password. Its that simple.
Needless to say, my friend was unimpressed and tried to get his 60 bucks back to no avail.
