Hi. I used to play chess and high school and the MonRoi Personal Chess Manager was my favorite tool. Helped me learn a lot. I have one for sale on ebay for cheap if anyone's interested. Gotta pay the rent. Lol

I agree that tactics and openings are important but there have been many young people in chess, 10 year olds, maybe younger--Bobby Fischer, Sammy Reshevsky, Paul Morphy are examples--who have become masters even tho at their age they have not had time to learn all that much. So what is the underlying secret? I believe it is approach, that is what they think about and how they look at the board. Find the correct approach and I believe one can become master!
