Advanced Chess

The article isn't very clear in explaining whether computer+human is ever any better than computer alone.

I guess this line

> A computer engine (Zor) ends first in the freestyle Ultimate Challenge tournament (2017)

implies that in the most recent tournament a computer-alone placed first.

In which case, what is the point of the human? Or, rather, if you are playing as a computer+human, why would you ever not pick its first choice?

(And this seems even more true now that Google's AlphaZero chess engine is out, which appears to be blowing the other engines out of the water, which were themselves beating humans trivially.)

It lists the best of the computer assisted players at 2755 rating until 2013, well below current world champion Magnus Carlsen rated 2876.
