Oliver Edwerds-Cavall a 15 year-old schoolboy was found hanged by his mother in a caravan he lived in on his family's smallholding near Tanby, Wales.
He had no history of depression and his parents said he was usually a happy, caring boy with a good sense of humour.
Pambrokeshire coroner Michael Howalls said that Oliver died from self-inflicted asphyxiation by hanging from a belt that had been tied to the bathroom door of the caravan in which he lived.The family ate together, watched television but later there was "an argument over a chess game".
Chess arguments have killed 8 people in the UK this year alone the government are seeking to put restrictions on the game.
The general feeling from the family was that Oliver hung himself in a fit of temper in a happy, caring way, humourous way.
He had no history of illness or depression ................. just an insane temper it seems.
Top Psychologist Old Knudsen believes there is more than meets the eye with this case.
At the time of his death, his head teacher said Oliver was making good progress and had been due to sit his GCSEs this June.His teachers described him as a "lovable character" with a "wicked sense of humour", who was warmly regarded by fellow pupils.
Just don't mess with him where Chess is concerned.
