It is not enough that he never loses, drawing is also losing points, and so
would give him a finite rating.
The question is, do you need to play perfect to draw the perfect player?

Doesn't matter if it is drawn or a win, the perfect player can only be certain
of a win if he has white and the chess is a win for white, or vice versa with
black.
I suppose we could ask a different question, if chess is a win for white and the
perfect player is allowed always to play white, will he still have a finite
rating? Probably not...!
However, that is not *fair*, he should play both sides, so it is hard to prove
he would always score a 100%.
What if he playes an almost perfect player, one that only makes a mistake in 1
in a million moves? Clearly that guy will have a finite rating, and he should
stand a good chance against the perfect player, probably scoring close to 50% =>
the perfect player will also get a finite rating.
