You could wand the players, for instance.
In an earlier tournament a witness claimed the following about the metal detection / wanding:
"...the machine went off close to her pants, and the arbiter still let her play."
https://www.chess.com/news/view/patrycja-waszczuk-cheating-2-year-banIt is a little bit funny but some people seem serious about having their opponents underware searched.
I have noticed some patterns in these reports from the Chess world:
There are already security measures in place but this does not appear to uncover anything. For example people are still found to have phones with them despite metal detection.
Usually there has been a growing rumor or suspicion regarding the banned player for some time.
The punishments seem to be fairly light and limited in scope. For example in one case a person banned from playing rated tournaments appears to have kept their arbitrator credentials.
There is also a trend of relaying on statistical tests. In these cases players can forfeit games because statistical tests indicated probability that there are some computer moves. This happened for example in a student world championship were the would be female student world champion forfeited all her games in the final, no appeal was allowed per the tournament rules and it was not referred to the disciplinary commission. The theory appears to be that this will deter cheaters, because their games are likely to be forfeited, and that forfeiting an occasional game (or the world championship title) is a small inconvenience as long as there is no further disciplinary action.
