MadChess 2.1 Released

  By

I have released version 2.1 of my chess engine. I built this version of MadChess using .NET Core, Microsoft’s new cross-OS development platform.

If you are feeling adventurous and would like to build Linux or Mac binaries, please refer to Getting Started with .NET Core on Windows / Linux / MacOS for instructions on how to build .NET Core applications. I have configured the MadChess project to build a self-contained application. All binaries required to run… Continue Reading
