Indian Grandmaster R Praggnanandhaa got off to a flier and defeated Firouzja Alireza of France in the Armageddon game in the first round of Norway Chess tournament here on Tuesday. After an easy draw under normal time control, Praggnanadhaa got 10 minutes as white compared to Alireza's seven but with the condition that he had to win as a draw would have given black extra points. The Indian was clinical in his approach and carved out a fine victory in the endgame.
