Chess player beat computer and was then electrocuted

[Boomer]

Alright, my roommate just told me this one, I think its total BS, but he seemed very confident and said he read it somewhere reliable. He even tried to make a bet with me that this did indeed happen, but when he tried to find the story, he couldn't.

Anyway, his story went that in 1990 or so in the Soviet Union, a man was playing chess against a computer set up in a weird way where the man moved real chess pieces made of metal against the computer (I can't quite comprehend how the computer moved pieces, perhaps there was a virtual board as well, I don't know). The man apparently beat the computer three times in a row, and when they started the next game, his pieces became electrified and when he grabbed one, he was electrocuted and died.

Someone please tell me and prove to me (so i can win the bet) that this never happened. Unless of course it really did happen, but I just find that so hard to believe.
