Sergey Karjakin played a brilliant exchange sacrifice on the way to defeating Magnus Carlsen in a classical game for the first time since Game 8 of their World Championship match in 2016. It was a dramatic turnaround for Sergey, who the day before had lost to Ian Nepomniachtchi after reacting badly to a novelty. In Round 5 Nepo overcame Richard Rapport in Armageddon, while a gamble from Alireza Firouzja paid off with a classical win over Aryan Tari.
