Or maybe his father

step-father and his trainer.

I'd point to Reti's Masters of the Chessboard, which gives an intelligent and broad perspective on chess. Was a real eye-opener for me.

Sunil is a true genius and it was fortuitous that he married Nakamura's mom and then nurtured his talent through the GM category.    I took a few lessons from him back in the 70s and he was everything you needed in a teacher; creative, enthusiastic and brilliant.  It's just that the expense of quality teachers is not something everyone can afford.  

The best teachers I have had over the years have been truly open minded and brilliant pointing toward classical sources for the subject matter.  The worst have been peddlers of stereotypes and simple ideas.

Thank you for all responses...I'm certain its beneficial to all rating levels...

Nice to know hard work pays off!!!

I'm looking forward to reading this book!  It will be in my hands in about 1 week.  What can I expect to learn?

"Chess training for Budding Champions" by Jesper Hall. A complete guide on practical training to become a master.

I strongly recommend this book as this has almost all of what you should have learn. The book encompasses the:

Pawn-Structure, Mental Training, how to use the computer, how to analyze the games, how to play positional and basic positions and guidelines.

That sounds like a great book nyLsel, I will certainly check it out.

you can expect to learn about outposts, weak color complex, developing pieces, clearance sacrifices, taking advantage of lead in development, How to use 3 minor pieces to fight a queen, pawn chains, attack/defensive tactics, and a legit way to draw.

Sunil is an 1. e4 player (from what I see from his book), and he likes King's bishop fianchetto (or the "Indian style") when hes playing black.

Thanks^

The Complete Chess Course by Fred Reinfeld

That's an old book, but I cut my teeth on it decades ago.  I'm going back through it right now, trying to get back into the swing.  His game examples lack the source, and some are perhaps "created" for the purposes of illustration, but as a one book solution, I think it's a worthy candidate.

Have been making steady improvements in my chess...thanks to all!!!
