I just whipped up a chess server, running on wss://chorus.mikedilger.com:444/ using all ephemeral events, no access control required.
I was having a horrible week, doing huge coding but getting no wins and probably have to throw out my efforts. I really needed a win. So I did this chess thing which was (for me) easy with super rapid progress.
Here is the protocol, anybody can write a client for this. People connect and get paired up and play each other. There is no fancy Elo score matching yet. Nor did I write a client yet. Just the server... which is currently running and listening for chess events tagging this pubkey(hex): dbb45efeb8cc10e6f75fdff7e561e7db39cc7ba6592f4c22e26f3ee36b2e7bc2
(NIP-64 is not related to this work... yet)
Please somebody write a nice client.
