For the first time in 10 years, there will be a World Championship without Anand, who has won the crown as many as five times.
Either Sergey Karjakin of Ukraine or Fabiano Caruana of United States will challenge Magnus Carlsen of Norway in the next World Championship match, slated to be held in November this year.
While Anand drew, Karjakin had to hold his nerves to hold a piece down endgame against Levon Aronian of Armenia and Caruana's endgame advantage did not prove enough as Peter Svidler of Russia proved equal to the American.
Karjakin and Caruana share the lead now on 7.5 points and meet each other in the deciding final round. Anand, on seven, is in sole third spot and his last round result will prove crucial in case the game between Karjakin and Caruana end in a draw.

If Anand wins, Caruana will have better tiebreak than Karjakin while if Anand also draws, Karjakin will take over in tiebreaks.
With just one round remaining, Anand will take on Svidler and the permutation and combinations do not give the Indian any chance although he can still tie for first with a victory.
Caruana played a very lengthy game and came close to winning against Svidler in a rook and Bishop versus rook endgame. However, by then the players were close to running out of quota of '50-moves' rule without any exchanges.
Results round 13: V Anand (Ind, 7) drew with Anish Giri (Ned, 13); Veselin Topalov (Bul, 4) lost to Hikaru Nakamura (Usa, 6.5); Levon Aronian (Arm, 6.5) drew with Sergey Karjakin (Rus, 7.5); Fabiano Caruana (Usa, 7.5) drew with Peter Svidler (Rus, 6.5).
