A friend and I wanted to make something else in GMOD other then only constructing. While making some contraptions, we started making chess contraptions, then I decided to make a map for them.
To work, download the files and extract them to your GMOD folder. In-Game, type "!load chess" (without quotes).
When the match end, clean up the map and type "!load chess" (without quotes) again for another game.
***YOU NEED VMF LOADER, OR THE PROPS WONT LOAD.***
