This is a most excellent place for technology news and articles.
I usually take the chess/checkers idiom to be more like "the left hand didn't know what the right hand was doing" Not that one is smart and one is dumb, but that they're going in completely different directions and playing by different rules.
Hmm, maybe I've learned the meaning wrong. English isn't my first language :)
No, you have the meaning right.
