Shane has the #1 Fargorate in the world at 820 at this time. I just stumbled upon this quote from Magnus Carlsen, the highest rated chess player ever:
"For me right now I think being the world number one is a bigger deal than being the world champion because I think it shows better who plays the best chess. That sounds self-serving but I think it’s also right."
It's definitely more difficult to become the top-ranked player in the world than it is to win a world championship.
