Russian chess player faces jail after video shows her allegedly poisoning opponent with mercury

In scenes reminiscent of the game's 20th century heyday, where dark rumours of subterfuge and sabotage swirled around countless Russian players, a chess player has been suspended from the game and faces up to three years in jail for poisoning her opponent… on camera. 

Everything happened at the Dagestan Chess Championship on August 2 and was first reported by a Russian Telegram channel before reaching government media.

In the event, Osmanova began complaining that she was unwell, nauseous and dizzy around half an hour after the game began. Doctors were called, who concluded that poisoning may have been the cause, and after reviewing the security footage (which can be seen below), the police were called and Abakarova was arrested.

The victim Osmanova later said she felt «terrible, disgusting, and morally depressed» after realising she had been poisoned, adding that another player had also fallen ill. «I still feel bad,» Osmanova told Russia Today. «In the first minutes, I felt a lack of air and a taste of iron in my mouth. I had to spend about five hours on this board. I don’t know what would have happened to me if I hadn’t seen
