Interesting SF offshoot

It plays an enormous number of chess variants (including regular chess):

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

It is truly strange that such a computer chess authority like you missed it, unless you are bumping this engine. SF-based variant engines are being there for a while under different names: Fairy-Stockfish, Multi Variant Stockfish... there are some names involved in these projects, making massive Elo gains over the time: Daniel Dugovic, Niklas Fiekas and Fabian Fitcher come to my mind, as well as some contributors like Fishtest way if I am not wrong.

Some threads can be found at TalkChess:

Fairy-Stockfish 10.3 released

250 ELO in ~ 10 months

Enjoy!

Regards from Spain.

I used to contribute cpu time to improve Fairy Stockfish.

Fairy Stockfish is used on pychess.org. One of the better variant websites.
