Topalov’s defeat has meant that Anand can win the title if he manages to beat Topalov in the final round on Thursday.
Playing with white pieces, Anand displayed excellent technique to outclass Hammer in 36 moves in an English opening game. The 45-year-old Indian grandmaster’s win has meant that he has remained undefeated in the tournament so far.

With this win Carlsen now stands in place sixth behind Fabiano Caruana. Following his loss to Anand, Hammer finds himself in 10th and last place behind Maxime Vachier Lagrave , Aronian and Alexander Grischuk. The final round takes place on Thursday.
