Malcolm Pein concludes his coverage of the final of the Skilling Open with a game which resulted in Magnus Carlsen’s birthday blues.
The reigning World Champion may not have appreciated the ‘present’ of defeat, but Wesley So was clearly intent on spoiling the party.
Malcolm’s Daily Telegraph column gives the looks at the decisive game and invites the reader to fond the winning line.
Malcolm Pein on…Carlsen’s Birthday Blues
Wesley So spoiled Magnus Carlsen’s 30th birthday and inflicted a rare defeat in online matchplay on the world champion as he secured the $30,000 (£23,000) first prize at the Skilling Open on Chess24.
The second leg continued in the same vein as the first, with Carlsen winning game one and So levelling the score. Game three was a rollercoaster that could have gone either way and ended in the first draw of the match. Carlsen played white in game four and quickly exchanged pieces to ensure the contest went to a two-game Blitz play-off. This tactic worked for Carlsen at the 2018 world championship, but not this time, as So struck what turned out to be the decisive blow in game five.
