Chess and business analysis: the 80:20 rule and Chess improvement

I’ve written a Chess article on using the Pareto Principle – also called the 80:20 rule. It’s published on NM William Stewart’s and GM Susan Polgar’s chess websites: www.onlinechesslessons.net susanpolgar.blogspot.com I’d love to get your feedback on this, either through YouTube or by commenting on the actual article. I hope this helps you increase your chess ratings!
