If ICCF had solved chess, all games could be agreed drawn before starting. The fact that they aren't indicates that the people @tygxc relies on don't believe him.
[It is of independent interest what will happen to ICCF now. Will they continue having tournaments without wins for a while, then get bored and stop?]
Fair enough, it would merely underline what we already know.
And while there is no GM team solving chess, I agree with the point that if there were a win, there would be no reason it would have to be easy to find. It could exist in a part of the 32-piece tablebase never visited by computers or people.
