Why Chess Mentor? Today I received a book in the mail entitled "How to Choose a Chess Move". I might be a rather good book, but after a few minutes with it I fell of to an afternoon nap, so for me rather than Choosing a Chess Move it resulted in me An Afternoon Snooze. I have never yet fell into sleep while using Chess Mentor. Besides that it is slowly moving me along toward making better chess moves.
Chess Mentor keeps me awake, stimulated and motivated. I will continue to improve through its use.
I'll give it more thought.
