Oslo: Praggnanandhaa walked out of the playing hall in the Norwegian capital with a Round 3 win and a 2-1 score in classical chess against world No 1, Magnus Carlsen.
The five-time world champion went from objectively winning to miscalculating, shredding the prospect of even salvaging a draw.
Seven-time Norway Chess champion Carlsen has dropped 13.7 points to 2827.7 Elo and is now in last place in the tournament standings.
Praggnanandhaa's second win over Carlsen at the event was described as a 'coin toss' that could have gone either way.
Carlsen compared his loss to his now-famous table-slam and defeat to the reigning world champion.
The Indian Grandmaster appeared to have surprised Carlsen in the opening, who wound up burning through his clock and 'wimping out a bit.'
