Fausti was one of the standout players of the World Cup, becoming the youngest participant in the event. He advanced past the opening round after winning the tiebreaks against GM Ante Brkic. In the second round, after drawing both classical games, he was eliminated in the tiebreaks by GM Vidit Gujrathi, the world’s number 27 at the time. Although his run ended there, his performance was historic, gaining Elo points and leaving a very positive impression on the international chess circuit.
