Chess Opening Book Ctg Download
HIARCS professional books in our chess opening book download product are many times larger with the latest human, correspondence and computer games. They are the strongest available opening books and are at least 100 Elo stronger than the free chess opening books hosted here.
iPhone, iPod Touch or iPad customers can now download custom books from this page for their device. Book customers should refer to the customer download page for our full tournament book in HBG format.
Please note for top performance in play you should allow HIARCS to use its own engine book which is included in the HIARCS installation and updated via the book access product. To ensure HIARCS is using its own engine book, you should turn off or unload any GUI books being used by the chess GUI you are using.
Each HIARCS product comes with its own chess opening book with the latest chess opening theory at the time of the release of the particular product. However, many chess players need to remain up to date with the latest chess opening theory throughout the year and online chess engine players like to have the latest and strongest chess opening book.
For many years HIARCS has had the strongest opening book available and it keeps getting stronger with every release. We even supplied the HIARCS tournament chess opening book to help World Chess Champion, Vishy Anand's team prepare for his World Championship matches.
The latest HIARCS tournament opening book is available in Chessbase CTG format (for PC), HIARCS' own HCS format for Mac and PC with regular updates for customers to the HIARCS Chess Opening Book CTG Access product. Improvements per year have averaged about 40 Elo points. Over the course of a year the opening book may contribute more to chess strength improvement than the increase in chess engine strength.
I have the up-to-date Mega Database 2020 and I filter all games with an B20-B99 ECO, which gave me roughly 1.2M games. Then I followed -kb/content/details/725/Creating%20your%20own%20opening%20books (You create a database, and then you import the games from this database in the blank opening book, et voilà.)
I first included variations and set length to 30 (gave me three ct* files summing up to 3GB) for then choosing not to include variations and set length to 20 (gave me three ct* files summing up to 2GB). (The 926 number is from the ChessBase tutorial.) Regarding the size (2-3GB) of the set of produced ct* files, it is for instance comparable to the size of the ChessBase Sicilian Najdorf 2020 opening book (which has only 3M games though), so that the problem that I have is not caused by a potentially too big opening book nor an opening book tree base on a number of game that is way too big.
The problem that I have is that so far, I only used official chessbase opening books (with Fritz on PC or DroidFish on android) and when I load such an official opening book, whatever may its size be, the engine plays instantaneously (because browsing the opening book is extremely fast for the GUI they're it, or for them).
With the opening books I created using ChessBase advices above, the engine don't play instantaneously, hence browsing though the opening book tree takes quite a long time. (For instance 1.e4 took half a minute when I play as black and the engine as white.)
How different are official ChessBase opening books from the one created with the ChessBase tutorial ? I guess that for opening books from the first category, the trees are somehow "optimized" when they aren't for opening books from the second category. 2ff7e9595c
