Magnus Carlsen won the Norway Chess Tournament for a fourth time in a row after beating Veselin Topalov in Armageddon on Friday. The world champion would not have grabbed the title had Shakhriyar Mamedyarov defeated Teimour Radjabov in their classical game. Radjabov held the draw despite having almost no time on the clock, allowing Carlsen to once again win his home event. | Photo: Lennart Ootes
