Where we can find Stockfish-dev (default)

[corres]

...
I'm sorry, but I don't understand what you mean by Stockfish-dev. The last version of Stockfish before NNUE was merged can be gotten here:
https://github.com/official-stockfish/S ... 32877c47a7
Click the green Code button and then Download ZIP.
Is that what you want?

Thanks. This source really belongs to the last (20.07.31.), the old Stockfish-dev.
It lacks only the development from that date what are in the NNUE version.

There is no such thing as an official Stockfish-dev that does not include the NNUE version yet is up to date.

On CCC Stockfish Classic plays (updated 16.08.2020.), authors are the old ones without Japanese contributors. The speed of Classic is ~50 % higher than SF+NNUE with classic eval.

You will need to contact CCC and ask them what they compiled to produce that binary.

Be aware that the name a Stockfish binary gives itself reflects the date that it was compiled.

Code: Select all

/// engine_info() returns the full name of the current Stockfish version. This
/// will be either "Stockfish <Tag> DD-MM-YY" (where DD-MM-YY is the date when
/// the program was compiled) or "Stockfish <Version>", depending on whether
/// Version is empty.

O.K. but the date of update is independent from the date of compilation.
