"you need to prove that the game ends in a 7 men table base draw"
++ Look at this game: https://www.iccf.com/game?id=1164344 it ends in a 7-men endgame table base draw, so none of black's moves need to be questioned.
no, I propose that black should have been able to win that from the starting position. disagree? prove me wrong.

"you cant prove to me that black doesnt win with perfect play on black's end?"
++ Of course we have evidence to that: millions of human and engine games especially ICCF WC Finals drawn games. White has the advantage of the initiative: 1 tempo, but not enough to win.
"by definition to prove that would be a weak solution for chess"
++ No, that is an ultra-weak solution only. a weak solution also shows how to draw.
