Cheating at Professional Bridge
Interesting article on detecting cheaters in professional bridge using big-data analysis.
Basically, a big part of the game is the communication of information between the partners. But only certain communications channels are permitted. Cheating involves partners sending secret signals to each other.
The results of this can be detected by analyzing lots of games the partners play. If they consistently make plays that should turn out badly based on the information they should know, but end up turning out well given the actual distribution of the cards, then we know that some sort of secret signaling is involved.

I play competitively, but am still a “beginner” as I have only been playing for a little over a decade. I play in local clubs, or in regional events. At my (low) level of play, bidding or play irregularities are common and inadvertent, and a director is as likely to be called by the perpetrating side as by their opponents. Perhaps I’m lucky, having never come across it.
In bridge, pairs do need to practice their communication, and understand the meaning of their bids during the auction and of their card play signals when defending.
An opponent can ask me about my partner’s bid or carding. And my least favorite answer to give is, “No prior agreement.” That’s bridge-speak for, “I have no effing clue what my partner’s last bid means. We never discussed what he/she just did, so your guess is as good as mine.”
