All the possible info (including my own ideas) gathered in one file is a unique way to always be well prepared!
I collect and gather theoretical material from important and most recent books and add my own ideas. The collection now includes over 10 000 theoretical analysis (quite many of them already have verbal comments) and is updated on a daily basis.
I teach many of these openings and many people also buy them in ChessBase/Fritz or pgn format. Prices range from US$10 to US$35 and counting by A4 pages material can range from 1 page to over 500 for a large and popular opening :). It is possible to get a discount, if you buy many systems or openings at once.
Payments can be done by PayPal and material (in Fritz/ChessBase or pgn format) is sent by e-mail. If you have any questions about openings, how to buy or anything else, send me an e-mail to yelena@yelenadembo.com .
New subscription – just US$ 5 per month for new opening ideas & updated variations sent weekly by e-mail!
