Boris Vasilievich Spassky (born January 30, 1937) is a Russian (former Soviet) chess player and former world champion.
He was born in Leningrad.
At age 18 he won the World Junior Chess Championship held at Antwerp, Belgium, and became grandmaster.
He won the 1966 candidate's tournament and the right to challenge the world champion, compatriot Tigran Petrosian in 1966. He lost the match, but earned the chance for a rematch three years later, and this time he beat Petrosian.
Spassky's reign as a world champion only lasted for three years, as he lost to Bobby Fischer (United States) in 1972.
