How to make a computer vs computer game on PC?

It would be cool to have a place in lichess where you chose the variant, and make a computer vs computer game.

Well if there would be such *variant* you said , then how can we play this *variant*!!!
And why to call it variant when there is no use of human !
Ya , BOT vs BOT can be the answer of yours first doubt!

If you know, please add a comment!

A variant is a type of chess. Like Atomic or antichess.

🤨 @ajTronic Well I didn't asked the meaning of variant!!! 😐
Though for more knowledge! Thanks!!!😊

To answer the OP: To play a computer-vs-computer Chess variant in Windows, download Winboard and Fairy-Stockfish.

github.com/ianfab/Fairy-Stockfish

This will allow a large number of variants to be played in computer vs. computer matches.

Try using chess gui
Banksia or nibbler or arena
Install engines and make them play.e

Arena is a good GUI for this. Local games on your pc.

Thanks for the sugestions! But is it possible on lichess?
