I would expect someone to be actually good at chess to put down their Elo rating. For someone just putting it as a hobby, I wouldn't expect much, especially when it comes to the "boring" stuff like memorizing openings.
In the same way that there is usually a difference between what high level athletes and hobbyist write. The former usually mention something concrete (champion of..., XXX league, a time or score, ...) while the latter just mention the sport, often among other things.
If someone had bad education credentials (bad school, dropout, etc) but they put a high SAT score on a resume that would be a pretty concise way of communicating "it wasn't because I'm dumb"
It’s possible that the received signal would be “I test well, but I struggle to complete a structured, long-term course of action”, which probably isn’t that beneficial.
I'd still prefer that to "I both test poorly and struggle to complete a structured, long-term course of action" which is just as likely an interpretation if you left it off.
At the end of the day, anything could be bad if viewed with sufficient cynicism, and you can't control how others will interpret what you present, you can only control the information which is presented.
