I am not asking if it is proven that chess is a draw with best play although I think it has been proven to my satisfaction.
If someone can find even one game where one side or the other won with out the other side making a mistake that would go against what I believe.
I believe from 62 years of playing chess and thousands of my own games that chess is a draw unless one side or the other makes a mistake.
I would suggest that out of billions of chess games that one cannot find even one game which was won or lost without one of the players making a mistake. If anyone thinks they can find such a game please post it here.
