Last year saw a couple of cheating scandals in the Bridge world. A number of the worlds top pairs were accused of signalling for opening leads by how they placed the bid tray, or showing suit holdings by how they played their cards. Apparently this had been going on for a while, but it took a combination of video evidence and some serious sleuthing before the whole thing went public.
While this has parallels to chess, it is obviously not the same as cheating using an engine. The closest comparison (at least to me) is when a player receives advice from another player. This has happened on a number of occasions (some quite famously), but as far as I know, very little action is ever taken (including by me). While FIDE has taken action to deal with computer aided play, it hasn't established robust mechanisms to deal with other forms of cheating (eg outside assistance or throwing games for cash )
The Bridge establishment is of course taking all this seriously, but as far as I know the actual ethics cases are still ongoing. if you want to dig through some of the detail you can visit bridgewinners.com where there are a number of articles and posts on the topic.
