Playing two computers

What to do and how to connect cables so that two computers play with each other using a chess program.

You need a chess GUI to play tournaments for chess engines via a network.

I suggest using Banksia GUI (BSG). It is easy, perhaps, the easiest way to do that. All your computers should be on a local network and you could use anything to connect them, from cables to WIFI. Typically, all your home/office computers use the same WIFI and that is enough for a local network (you don't need any cable). Your computers can run with any main OS supported by BSG: Win, Mac, Linux. You just need to check firewall/network permissions to make sure those computers can see and transfer data to each other.

After running BSG on each computer, go to the menu Connect/Local network to open the panel, assign it a name and click on the button "Connect". You will see some new engines with double-colon prefixes such as "rm::Jane::" from other computers (e.g., "rm::Jane::Stockfish 241005"). Just pick them (similar to the way you pick a local chess engine) to create a new tournament and all done. BSG will automatically do the rest for you.

The below image is the Local network panel on BSG. The image is a bit outdated but you could have a glance at it:

Thank you for your answer. Unfortunately, your program is not suitable for this. There's still an error that I reported and you haven't fixed it.
