Opening</sub>

I share two books with you, with two different configurations of the opening repertoire and their percentages.
The version that has 80% is the one I use for tournaments, and the first to vary repertoire. The statistics are what they are both in classical chess, as a reference for games with a classical rhythm and above 2700 ELO fide, and with the chess engines, unless there is an error in the opening, the engines will end up determining that chess is a draw. But until that happens, you have the possibility of activating Nf3 with the same percentage as c4. But e4 seems like no one doubts that it obtains more victories than with d4 among chess engines.

_{Release the update of LesChats bin book}

In this new update, the reviewed and analyzed games have been added. Along with the Poly17 tool that has previously added those games to the book. We return to the depth of 40, we have already tried with 80, and although I add more depth when creating the updates, in Sedat tournaments the engine is different from Eman and all my books have Eman's analyzes. Then I prefer to let Raufbisch play and choose the path based on his analysis. I hope you like it and enjoy this book that has many hours of analysis and only games from my servers.

_Settings

With Eman Best move on
Width=2
Depth=40

With other Engine, bestmove disabble and depth 80 for play into playchess or lichess.

_{Update16012024 Leschats bin series}
Quite a few games have been added due to the increase of one more server as a tool to contribute to the community. Some errors have been fixed that I have detected from the tests carried out by a forum user, whom I thank for doing so with leschats, because it has also helped me find more depth without, in principle, errors. Although we already know that the chess engine in such short times and with the new dual net, we would have to see if it interprets the position correctly or not. In any case, for this update we are going to set a depth of 80 and bestmove off, except in Eman which is on (width=2) following Omar's instructions. The result that this specific book can offer is in the % of Africanata, Senufo or Yorubachess nicknames in lichess. With a high draw rate, but with a reasonable % of wins without any defeats for at least a month. Then I hope you enjoy it and find faults, use it with your engines for your tests, in short, that above all there is fun.

For bullet test benches, although it may seem strange, I recommend depth of 40.

Playchess and lichess games have been added that have been analyzed and manually tuned with scid vs PC. In playchess with engines like Eman, Brainlearn, and the well-known ones, it seems to have optimal performance so that the chess engine can play the middle game without a big difference in evaluation for both white and black. In the next updates, we will add more variations thanks to the UHO tests carried out. I hope you can enjoy it. A cordial greeting.

_{Update 150324}


With this new update, basically playchess games from five minutes onwards have been added. I recommend a depth of 20 for bullet, 12-16 blitz, 6-10 for over 60 minutes. It is configured as follows:
80% e4; 20% c4; 10% d4. Because with the database that I work with, they are the percentages with the most probability of winning at the start with white. A greeting and I hope you enjoy it.
