I know you think a recording fixes everything and sets the bar high. All it takes is a bathroom break to consult an ai on a phone or other laptop (and that has happened in the chess world). Maybe that’s all a player needs to turn a game around at a critical point.
You can try to tell players they’re not allowed take bathroom breaks or smoke breaks etc. But what if someone knocks on your door and you’re home alone, what if you’re expecting a delivery, or have some other reason to need to answer it. The rest of the world doesn’t stop for two hours because a go tournament is on.
I you think the bar is high here, but people who want to cheat go to great lengths. Streamers who want a world record in speed running manipulate footage. And since this is just a recording you could probably edit it well enough to cover up things. In speed running some cheaters were only caught when very niche things like the audio file not looking normal but sounding very normal. Jump to ~10:49 below
Historically or? The Women’s Championship, http://gocentre.londongo.club/events/ewc-2021/, requires everyone to record.
All players must video record their play (example video ) and be able to provide these on request.Players unable to provide a video of sufficient quality on request might forfeit the game and/or be disqualified from the tournament.
This was mentioned at the top of the other thread we discussed in
