It was clear from the beginning of the fourth round that the GRENKE Open is one of the toughest chess tournaments in the world. Several players made the decision to agree on quick draws in order to save their strength for coming games. Among them were Andrey Sumets and Nikita Vitiugov, who had already finished their game before other players entered the room. Of course battles were also fought in the main field, and nine strong title holders will continue further in the tournament after the first four rounds. Among them is the Swedish Nils Grandelius pictured below.
