There are several sources of PGN files, my favorite one is https://database.lichess.org/. It takes about 30 minutes to parse 190 GB file on normal HDD.\n\nProgram has been written in C# for .NET Core 3 platform. It uses [CommandLineParser](https://github.com/commandlineparser/commandline) (to parse parameters) and [ShellProgressBar](https://github.com/Mpdreamz/shellprogressbar).\n\n# Usage\n\n```\n-i, --input             Required. PGN input file to process.\n-o, --output            Required. ABK output file.\n-p, --plies             (Default: 2147483647) Maximal number of plies to parse.\n-e, --elo               Minimal average ELO of players to parse the game.\n-t, --time              Minimal initial game time (in minutes) to parse the game.\n-m, --multithreading    Enable support for multithreading.\n--help                  Display this help screen.\n--version               Display version information.\n```\n\n# Example\n\nInput: `PGN2ABK.exe -i .\\lichess_db_standard_rated_2013-01.pgn -o .\\generated.abk -p 20 -t 15 -m`\n\nOutput:\n![Output](https://i.imgur.com/J4FcrwN.png)","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftearth%2Fpgn2abk","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftearth%2Fpgn2abk","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftearth%2Fpgn2abk/lists"}
