There are no relation between math and chess.
Is chess easier or harder than math?
How can you say high level math is significantly more difficult than chess when it is humanly impossible to come anywhere near playing a perfect game of chess? Bobby Fisher tried and he never was able to. Any super gm is definitely intellegent enough to be a math genius easily.
Chess tests every single part of your intelligence and you can play your whole life and never even be able to play a half decent game.

chess does NOT test every part of one's intelligence nor does math
there are a lot more gm's than there are stephen hawkings
Stephen Hawking of course being the Kobe Bryant of math having won 5 Fields Medals

Chess has a limited scope and mainly the art of recognising and building patterns in a well defined system. Mathematics is unlimited in scope and can expand in any direction that the mathematical mind wants to go. I think mathematics are much harder than chess.

Chess and math have a lot similarities in the way you are thinking ! Eg, if you have to solve a problem or to find the best move, the way you are thinking !!

As you've said in your opening post, gotta have love in order to succeed in either. But i'd say Math is harder (Analytical Geometry is the highest math i'd achieved in high school) as studying Rueben Fine's Practical Chess Openings-in Descriptive Notation-was definitely easier.
Chess is easier... even if you mess up your opening moves you could still end up winning the brilliancy prize
, not so with maths forget your theorem and your solution is ziltch.
