Query: Essential reading for the thinker

This book helps a particular type of player and hurt others. The information is great for anyone that can use Sklansky's work as a springboard to deeper thought, but can lead many to mismanage variables while sizing up a situation. Not Sklansky's fault, but the reader. This was the first poker book I ever read and I misused the understanding at first for increased losses. However, overtime, Sklansky's thinking here has helped at the tables and off the felt as well. I recommend this title as an essential book in a serious poker players library.
