As far as I'm concerned, the #SinquefieldCup is finished after this round. I see nothing wrong with a tournament ending in a tie any more than I do with a game ending in a draw. It's as silly as using a tie break on an individual game.
#grandchesstour Why have any tie breaks? What's wrong with defender retaaining title on a tie? It makes no more sense than a tie break for individual games that end in a draw.
