From the Sydney Morning Herald:
Initiated into chess early on by his father, as a boy Magnus nevertheless preferred other pastimes that he explored on his own.
Aged two, he could recite all car brands; as a five-year-old, he built monumental creations out of lego; then he moved on to memorising the world's countries, their flags, capitals, and areas.
But he was soon brought back to chess by the desire to beat his older sister at the game.
