Indian chess star Viswanathan Anand suffered a shock loss to Magnus Carlsen of Norway in the fifth round and slipped to the joint seventh spot in the Tal Memorial Tournament here.
Playing the last classical game against Carlsen ahead of their World Championship match scheduled in Chennai in November, Anand could not find a suitable plan and was outplayed by the young Norwegian in what could be termed as a rude wake up call for the Indian world champion.
Boris Gelfand of Israel joined Hikaru Nakamura of United States at the top of the tournament standings on 3.5 points after winning his second game against Alexander Morozevich.
Nakamura played his first draw in the tournament sharing the points with Russian Dmitry Andreikin. The result means that all the four Russian participants are yet to score a victory in this tournament.
With Gelfand and Nakamura in front, Carlsen and Mamedyarov are close behind on three points each. Andreikin and Fabiano Caruana of Italy share the fifth spot on 2.5 points while Anand and Karjakin are joint seventh on two points each.
While the focus of the world stayed on the Carlsen-Anand game, Andreikin did well to keep Nakamura in check. The American had won three games in a row and was raring to go but was denied any leverage by the Russian.
In other games of the day, Mamedyarov drew with Caruana while Kramnik played his third draw in five games, sharing the points with Karjakin.
Round 5 results: Magnus Carlsen (Nor, 3) beat V Anand (Ind, 2); Boris Gelfand (Isr, 2.5) beat Alexander Morozevich (Rus, 1.5); Hikaru Nakamura (Usa, 3.5) drew with Dmitry Andreikin (Rus, 2.5); Shakhriyar Mamedyarov (Aze, 3) drew with Fabiano Caruana (Ita, 2.5); Vladimir Kramnik (Rus, 1.5) drew with Sergey Karjakin (Rus, 2).
