Giri's Short King

Carlsen's reluctance to stay on board one in Doha brought there Kramnik, who on his turn freed it to the young and shiny Anish Giri.

One Mistake

The only decisive game in round two of the Shamkir Tournament was the one between the world champion and the Azerbaijani's highest rated representative. Mamedyarov committed just one mistake in the opening but this proved one too many:
