# Gensfen
`gensfen` command allows generation of training data from self-play in a manner that suits training better than traditional games. It introduces random moves to diversify openings, allows reduced pruning, disabling of TT for less interference between searches, and fixed depth evaluation.
`gensfen` command allows generation of training data from self-play in a manner that suits training better than traditional games. It introduces random moves to diversify openings, and fixed depth evaluation.
As all commands in stockfish `gensfen` can be invoked either from command line (as `stockfish.exe gensfen ...`, but this is not recommended because it's not possible to specify UCI options before `gensfen` executes) or in the interactive prompt.
`gensfen` takes named parameters in form `gensfen param_1_name param_1_value param_2_name param_2_value ...`.
It is recommended to set the `PruneAtShallowDepth` UCI option to `false` as it will increase the quality of fixed depth searches.
It is recommended to keep the `EnableTranspositionTable` UCI option at the default `true` value as it will make the generation process faster without noticably harming the uniformity of the data.
`gensfen` takes named parameters in the form of `gensfen param_1_name param_1_value param_2_name param_2_value ...`.
