I'm surprised no one has mentioned the famous Titiov exploding head incident. From that bastion of scrupulous journalism, the WEEKLY WORLD NEWS, May 24, 1994:

Doctors are blaming a rare electrical imbalance in the brain for the bizarre
death of a chess player whose head literally exploded in the middle of a
championship game!

No one else was hurt in the fatal explosion but four players and three
officials at the Moscow Candidate Masters' Chess Championships were sprayed
with blood and brain matter when Nikolai Titov's head suddenly blew apart.
Experts say he suffered from a condition called Hyper-Cerebral Electrosis
or HCE.

"He was deep in concentration with his eyes focused on the board,"says
Titov's opponent, Vladimir Dobrynin. "All of a sudden his hands flew to
his temples and he screamed in pain. Everyone looked up from their games,
startled by the noise. Then, as if someone had put a bomb in his cranium,
his head popped like a firecracker."
