If the match goes to the third duel, the underdog gets to choose the setting.
If the first duel is a draw, the 2nd duel is selected by the underdog.
If the first and 2nd duels are draws, the 3rd one is random.
If the first duel has a winner, and the second duel is a draw, the underdog gets to choose the setting.
If the first duel is a draw, and the 2nd duel is won by the underdog, then the third duel is random.
If the first duel is a draw, and the 2nd duel is won by the favored, then the third duel is chosen by the underdog.
