This sounds similar to an article I read about major league pitchers, who must learn to avoid "tells" for the pitch they are about to throw, while opposing teams pour over video of their previous outings looking for those tells.

Some pitchers even said they would deliberately perform a "tell" that opponents had identified then throw a different pitch.

Same thing happens in football with audibles. I wonder how many teams are feeding videos like these to AI and asking it to find patterns that might be tough for humans to see. If an AI thinks there's a pattern, verifying shouldn't be too hard either.

My personal favorite example of this in football

Legendary variation from pro tennis between to HoF players, https://www.independent.co.uk/sport/tennis/andre-agassi-bori...

In the exact same way, in cricket there is a style of bowling called legspin and bowlers who use that style have a particular type of ball called a “googly” which turns in the opposite direction to a normal legspin ball. Because legspinners sometimes have to do weird wrist contortions to get this ball to work, batsmen practise trying to “pick” this ball by noticing these tells (mainly whether they can see the back of the bowler’s hand).

So really crafty legspinners sometimes try to develop two versions of the googly: one with a deliberate tell and one without a tell.

Here’s an example of probably the greatest legspin bowler of all time doing exactly this, although with a different ball (a “flipper” or topspin ball) not a googly https://youtu.be/DlyG5wnW7I0?si=O463NAdV6NAAB3cG
