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.
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.
