Russian chess player poisons rival's board with mercury

In world first, Russian chess player poisons rival's board with
mercury

At least it wasn't novichok.

Russia is no stranger to unique poisonings. State agents have been
known to use everything from polonium-laced tea to the deadly nerve
agent "novichok" when making assassination attempts against both
defectors in the UK and internal political rivals like Alexei Navalny.
But a new "first" in the long history of poisonings was opened this
month in the Russian republic of Dagestan, where a 40-something chess
player named Amina Abakarova attempted to poison a rival by depositing
liquid mercury on and around her chess board.
