January, 21 2021: I have updated all the customers up to 1st November (or so) and all the subscribers, if you are between them and don't find your e-mail please check in your spam folder or write me back.

This latest Goi update has proven to have a very dominant influence by the Réti opening (1.Nf3), in a recent tournament by Oliprog the book opened in this way very, very often. For this reason I advice you to set the Learning Strength to 10 (ten) with the CTG version on the newest Fritz where the maximum is 500 if you are doing tournaments between books of if you want more diversity in the game.

Goi opens 1.Nf3 (Réti opening - A04 NEW!), 1.c4 (English opening - A10), 1.e4 (King's pawn opening - B00) and 1.d4 (Queen's pawn opening or Queen's pawn game - A40) as White, 1 ...e5 to 1.c4 (English opening - A20), 1 ...e5 to 1.e4 (King's pawn game - C20), 1 ...Nf6 to 1.d4 (Queen's pawn game - A45), 1 ...Nf6 to 1.Nf3 (Reti opening - A05), 1 ...e5 to 1.g3 (Benko's Opening - A00), 1 ...e5 to 1.b3 (Nimzovich-Larsen attack, modern variation - A01) and 1 ...d5 to 1.f4 (Bird's opening - A03) as Black.

I added the Réti opening to introduce more gameness. The Sicilian Defense is still blacklisted as Black, instead. Remember to enable Tournament Mode if you are using the CTG version.

By now the lines for any opening up to the 10th move are so accurate that I can tell this book is not anymore only adviced for blitz games but for correspondence chess too, if you strictly follow the green moves (CTG version). In facts I have checked them and fixed them for years versus the strongest opponents books and players using a serie of always more powerful tools; the last one in this list is the stabels monster machine with the newest Stockfish and 126 threads.

I feel pretty confident to tell that the BIN version is slightly stronger than the CTG because of a Fritz crazyness in which the interface makes move the engine unaccordingly to the book, while its Polyglot counterpart is directly connected to the UCI engine, therefore it forces to move with its variants. The BIN book in Droidfish is also slightly better on the first move for White as it shows the correct percentage, unlike the CTG one (this issue is present only in the White first move anyway, just set Book Randomization to 50% if you have the CTG version and if you want to study the variants, 20% if you want the maximum performance while playing).
