You have forgotten the old rule...
"Those that can't do, teach"
I am only a NM and have been retired from OTB chess for many years...so would you buy a book from me that taught you what I have taught people here?
Tony and some of the other old timers will tell you that I really helped their game by looking at there personality and I believed it should follow over into chess. If you are a closed person and don't like to talk to much then d4 openings and closed positions are for you. If you are an outgoing person and can never shut up ( like me
) then open positions and gambit lines are for you.
I am not saying it is a perfect idea...but it really has worked for alot of people.
Would you buy that book if I really sat down and went over the games and analysis of those and showed the before and after results and had the interviews and all and showed beyond a shadow of a doubt of how you could utilize my theories to help your game? Cause in the beginning you might think you are Tal...when really you are Petrosian.
Even though I have not played in an OTB tourney since 98?
