Youth and Early Chess Career (1995 To 2004)
Carlsen learned how to play chess when he was five years old. However, he didn’t show much interest at first. He instead amazed other people by completing activities that demonstrated his general intellectual aptitude at an early age.
At two years of age, Carlsen could solve 50-piece jigsaw puzzles. He also played with Lego sets intended for children 10 to 14 years old. When Henrik Carlsen, his father, introduced him to chess, the five-year-old was busy memorizing the areas, population numbers, flags and capitals of every country in the world. Later Carlsen completed a similar task—memorizing areas, population numbers, coat-of-arms and administrative centers—for nearly all Norwegian municipalities (there are 422 municipalities today).
