        file.ini    - Read configuration from this file (after reading nocheto.ini)

Debug

Use --debug to debug nochetodbeval. This is for developing purposes only, you probably wouldn't need to use it.

Config

Use --config filename.ini to read configuration file.

Nochetodbeval always read ~/.nocheto/configs/nocheto.ini file first and then the file required by --config option. So you can use this to create ini configuration with different configuration for different usage.

The filename can be absolute path (i.e. ~/.nocheto/configs/tweak.ini) or just a basename (i.e. tweak.ini) in which case the full path is assembled from this basename and ~/.nocheto/configs/.

Chess 960^1.1.0

Use --chess960 to evaluate chess960 positions (default is evaluating standard positions.)

So, to evaluate all positions in database, you must run nochetodbeval twice. Once with and once without --chess960.

Engine

Use --engine engine to change engine used for play and analyze games. It is recomended to use this options, in case you changed engine in nocheto.ini for playing in nocheto.

Go (seconds)

Use --go seconds to change number of seconds to think about one position. It is recomended to use this options, in case you changed goseconds in nocheto.ini for playing in nocheto.

Threads

Use --threads number to change number of threads used by engine. It is recomended to use this options, in case you changed threads in nocheto.ini for playing in nocheto.

The value should by the same as number of processor units your computer have.

Not every engine actually use this value. But stockfish does.
