goi.bin opening book

So when are we expecting Goi6 2.1 here..we wanna see some tournaments or test from your latest book please...please...GOI6.2.1...thanks 

I apologize for not having updated this thread with the new presentation, but I was after family businness, plus I wrote already three followings posts, hence I was not permitted to write anymore.

Yes, tests were very good, but in date October, 29 they are already obsolete, as there are new books. Anyway:

Download games here.

The shop will be opened still for a week, after that I will close for holidays for a couple of months and I'll dedicate my time only to the subscribers. The ones purchasing goi 6.2.1 will get also Goi 6.2.2, a book reserved only for susbribers otherwise. For those interested to the subscription: there will be a Goi 6.2.2 in both BIN and CTG format and there will be a Goi 6.2.2 GOLD in BIN and CTG format. These days I'll work to update to Goi 6.2.1 ABK also the ones who bought Goi 6 ABK.

Can't understand how to use two books there

Pls help

Goi Opening book.

September, 4 2020: In this update many lines for Black for the Semi-Slav and the Four Knights Opening have been fixed, plus alot of games have been added.

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 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 you are good to go).

Move #1 stats:

Goi opens 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've considered the Sicilian defense not enough productive as Black because the book received too many losses and the positional evaluation score was too high for the White right from the start.

January, 4 2021: I have updated all the customers up to 29 October (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.

There is a new feature on this version of the book: the Réti opening (1.Nf3) has been re-enabled since these NNUE networks gave it a big positive score at the start.

Goi opens 1.c4 (English opening - A10), 1.e4 (King's pawn opening - B00), 1.d4 (Queen's pawn opening or Queen's pawn game - A40) and 1.Nf3 (Réti opening - A04) 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.

The Sicilian Defense is still blacklisted as Black, instead.

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).

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).
