Lost ability to concentrate as opponent was wearing a watch: Magnus Carlsen after loss

After losing to 23-year-old Kazakh Grandmaster Alisher Suleymenov at Qatar Masters, five-time world champion Magnus Carlsen said he lost his ability to concentrate after seeing Alisher was wearing a watch. He added, "I...take responsibility for my inability to deal with those thoughts properly...but it’s...incredibly frustrating to see organisers still not taking anti-cheating seriously at all."
