No, please don't apologise. Thank you for brining up a great point!

Running something as complex as Lichess is... unwieldy when all I wanted was something I can quickly spin up in 5 mins on nearly any server, with a simple mobile interface for my father-in-law and child, and easy-to-debug (Lichess uses websockets which are often blocked by state firewalls).

If you don't have to deal with an amorphous state actor and a very different Internet culture, then please use Lichess. :)

Out of curiosity what kind of traffic is safe?

In the context of chess I would imagine passing JSON around via EventSource/SSE should be more than enough.

		I'm not sure. The GFW is rather tricky and is known to do DPI. For now, yes we are communicating moves in exactly the way you described EventSource! Eg: { "fen": "rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1", "status": "active", "turn": "b", "white_ready": true, "black_ready": true, "spectators": 1, "in_check": false, "last_move": "e2e4", "game_over": false, "available_colors": [], "reservations": { "white": {"reserved": true, "expires_in": 0}, "black": {"reserved": true, "expires_in": 0} } }
