Related: World champion Magnus Carlson recently resigned a match after 4 moves as an act of honor because in his previous match with the same opponent, Magnus won solely due to his opponent having been disconnected.
His opponent, Ding Liren, is from China, and has been especially plagued by unreliable internet since all the high level chess tournaments have moved online. He is currently ranked #3, behind Magnus Carlson and Fabiano Caruana.
