This is the blog post that introduced me to the idea that human + computer might be better a computer alone: https://rjlipton.wordpress.com/2015/07/28/playing-chess-with...

It's called Freestyle Chess or Advanced Chess. Humans have beaten the best computers this way, but I'm not sure it is clear that human + computer outperforms a computer alone consistently.

Incidentally, that's a great blog to browse if you like chess and math/CS theory.
