Does anyone have "The Six Power Moves of Chess?" Is it useful?

Sort:
Samurai-X

Looks like it has good reviews, but so do many many other books on Amazon. Does incorporating the six power moves significantly improve your chess?

I have it and enjoyed reading it.  My observation is that it is a systematic way of looking for threats.  It classifies them into the 6 'power moves.'

Samurai-X

Another forum lists the Power Moves and, at least on surface, they appear to be too simplistic. That's my concern.
