Consider the final state of the game. The discard pile, where the ties go, has an equal number of red and black cards. Therefore the total number of cards remaining--in the win piles of each player--consist of an equal number of cards.  Therefore both players have the same number of pairs. Thus every play of this game results in a tie, which is a loss for the challenger.
