They will have to be careful about whom they invite because this sadly seems ripe for cheating.

I know there will be cameras on the players and analysis software will be used to catch anomalies, but with this much money on the line I don’t think those measures will be enough to discourage bad actors.

It's not strictly true that chess is the only sport that is the same whether played over a board or online, poker comes to mind, and in fact most board games would qualify.

Regardless, as a chess fan it's great to see them adapt to the current circumstances.

Online poker misses a lot of non verbal communication (intentional or not)

Live tells aren’t taken that seriously or considered a significant factor outside of laymen.

That said I do think the dynamics of poker change more than most other board/card/table games when going from live to online or vice versa, with my extremely limited understanding of chess, go, and Magic.
