KP is very informative about how to play when you have an M<10. The push/fold strategy is far from optimal in deeper stack situations.
Twoplustwo.com's own Mason Malmuth gave the book a rating of 10 out of 10. (And, no, the book wasn't published or sold by 2+2
)
KP is basically for beginner's, while KE was written for more advanced players.
