The “He’s playing chess and everyone else is playing checkers” thing is done.
It’s really, really done. There may have been a time when this metaphor seemed clever and biting, but I doubt it. Either way, it’s become a meaningless bit of syllabic drivel. It’s stupid-speak. Unoriginal and lazy.
If you use this overused, hackneyed expression, you are just as overused and hackneyed.
While we’re at it, all references to someone playing “three dimensional chess” are also finished. This is just as overused and stupid as the chess and checkers thing.
Please think of something new and more clever to say or shut the hell up.
