A day after stopping Boris Gelfand 2.5-0.5 for his first win in the chess24 Legends of Chess, Viswanathan Anand crashed to a stunning defeat, by a similar margin, to an otherwise struggling Ding Liren in the eighth round on Tuesday.

Surprisingly, Anand lost both his games with white pieces rather tamely. In between, he drew with black.

In this battle involving two players out of reckoning for a place in the semifinals, Anand faltered early in the first game with a knight-retreat and soon found his castled-king on the queenside come under fierce attack. Anand saw no way of saving the position and resigned inside 25 minutes of game-time.

In the second, where Anand played black, the battle was fought on an even keel. In the third, Anand erred more than once after the opening lines of Sicilian Najdorf. His position fell apart and he lost his queen before resigning.

In the most watched game of the day, leader Magnus Carlsen let second-placed Ian Nepomniachtchi off the hook after gaining a firm grip with black pieces but crushed the Russian in the second. The third game, where Carlsen held a clear advantage, ended in a draw.

In the remaining contests, Vassily Ivanchuk and Peter Leko bounced back from defeats in the second game to draw level with victories in the third, against Anish Giri and Boris Gelfand. Vladimir Kramnik, too, came close to levelling the match at 1.5-1.5 against fellow Russian Peter Svidler but could not convert a sizable advantage into a win in the third game.

With both Russians in contention for two available semifinal spots, the winner of this match will considerably brighten the prospects of reaching the knockout phase of the competition.
