Hello everyone, I have created this thread, to comment on any questions we may have regarding holding a chess engine tournament and opening books on the Android platform.

So is well to let the option Best Book Move ON even if I put just one bin book and is place for two bin books?

If you use an opening book in "Best Book On" mode, you will get to know how hard the book can play.

However if you use 2 books, the first book can be very strong in a game that can be wasted by the second book.

From this it follows that when you play with 2 books, you must be clear that the first will affect the second book in its development.

Everything will depend on how you want to carry out the tournaments, with what objective.

M9.5 playing

I understand. The Last questions for you is : In your tournament : for example, 3.Cichess 041020+ Kain New ( 3702 elo ) use nnue and Kain New bin book, right? What nnue use în your tournament to reach 3702 elo. You set Kain New book to Best Book Move : Off or ON? What is the best performance with Best Book Move Off or ON?

Thanks. And If you can send me Kain New bin book. Thanks so much for your great help.

Send me the configuration ( settings ) of this engines in your android tournament :

The "NNUE" networks that I use in my last tournaments is the "NNUE" which is integrated into the chess engine.

The "NNUE" networks have a number or code, but that same network, you can identify it by the original name of the author.

This is what happens with Sergio Vieri's networks.

Depending on the pace of play or rather the depth of play per movement that the engine plays, it will make the opening book more or less effective.

Books are usually effective in fast games and depth less than 24.

For long times and powerful hardware the book will lose effectiveness. It is due to the new increase in Elo of the engines thanks to the "nnue" networks Results vary depending on how the tests are performed. I use a database with opening variants to see if the opening book can play those variants.

Try playing with the books by activating only 8 full plays for serious games, with long time controls or with depth of movement greater than 25 depht

All right. Thx.

And... CiChess_041020+nn-140820SV-1035____3705 Elo, have a power of 3705 Elo at his default values?

PLEASE IF YOU CAN TO SEND ME THE STRONGEST ENGINE WITH EMBEDDED NNUE FOR Android ARM 7 WITH ELO OVER 3600. HERE. AND STOCKFISH 12 NNUE WITH LAST NETWORK. ( NO Stockfish POLYGLOT 12 NNUE, because isn't functional on my Tablet ). Thx a lot, a lot men.

Thank You.

And when you make an engine duel with Kain New Bin Book or another book, you put the path of book in Book File, and leave the option BEST BOOK MOVE ON?
