Suppose you wanted to rebalance the rules of chess so that the black pieces had equal odds. You really only need to achieve this at the superhuman skill level, and then you could let the matchmaking algorithm could do the rest of the work.
You’re making this up. Chess is not solved.
It’s also largely irrelevant to my point.
I think it is highly likely that perfect play results in a tie for both sides.
Saying black can at best tie against perfect play is not the same thing as saying both players can at best tie when facing perfect play.
