Also of note is Leela Chess Zero, which is essentially the open source, weights available reimplementation of AlphaZero, trained using decentralised training among other things, I believe. A lot of the work Deepmind did with AlphaZero had to be painstakingly redone by the community and it took years. I'd feel bad if I didn't mention them too, they've done a great job. I'm working on my own weird ideas within this space that are quite different from both stockfish and leela zero(but partially taking inspiration from both) but that's still very much under construction...
