Sokolsky Opening: Symmetrical Variation Now on Kindle

I've published this chess monograph, "Sokolsky Opening: Symmetrical Variation", in January 2006. This booklet has the following chess moves: 1. b4 b5!? And it also has 39 chess diagrams and 40 completed chess games.

On July the 2nd, 2015, this original chess monograph has been converted in a Kindle eBook. And it is being sold on the Amazon.com website in United States, the Amazon.ca website in Canada, the Amazon.co.uk website in United Kingdom, and other Amazon websites around the world!
