After a long stop for personal reasons I decided to start again with my opening book, redesigning it totally from scratch. This implied a lot of work and months of tests.

Goi 7 is ctg only and it was made only by adding games and using the learning function, no hand work was made, except for the removal of the first moves that are unuseful to win games between chess engines.

Goi 7 opens only:

  1. e4
  1. d4
  1. c4
  1. Nf3
  1. e3
  1. g34


Here's a few stats:




This book is extremely compact in size (only 19.3 megabytes) and it stores 269.436 moves.

Results of the last tournament I've made:

September 2025 book tournament, Blitz 4. 2025

All past customers have to buy a new license if they want a copy of this book.

Note dated March 5, 2026: I'm still getting people opening disputes on Paypal for the same problem of the past years. So, for anyone visiting: I’m not selling a large number of licenses, so I don’t have a payment gateway connected to this site. Therefore, I have to manually check PayPal and send the link afterward, when I see the transaction in my account. I usually check PayPal once a day. Since this is a manual process and not continuously monitored, there may occasionally be a delay (depending on sales volume or personal commitments), so, please, allow 1–48 hours for delivery. If you purchase the book, please keep an eye on your spam folder: sometimes e-mail providers classify my e-mails as spam, since the first one I send contains a link (to download the book). Thank you for your understanding.
