Can metal detector detect a gram of Silicon(except transistor I think there are non metallic replacement for everything)? Also, many players bring their own beverage in their container. Seems pretty steep to ban everything for a small minority of cheater.

Can a computer small enough to contain a chess engine be fitted into one gram?

The players beverages would also have to be taken out of their original container and transferred into a tournament-provided container.

IBM has 1mm * 1mm chip comparable in performance to 1990 Intel, likely much lower in weight than 1g along with photovoltaic cell for power[0]. I don't think this is enough for beating Magnus, but it could at least find tactics.

It is like hearing about ambassadors who dont implement strict rules to defend the embassy against spies.
