Alexey (Aleksei) Stepanovich Suetin (16 November, 1926-10 September, 2001) was a Russian chess Grandmaster and a chess writer.

He spent most time of his life in Moscow and was a mechanical engineer by profession. He was awarded the International Master title in 1961, becoming a Grandmaster in 1965. His philosophy: "mastery is not enough; you must dare, take risks".

In 1955, he played at the World Student Team Championship as a member of the Soviet team, winning individual and team gold medals with a score of 80 %.

In the 1906s and 1970s he achieved stunning results at several tournaments. He won at Sarajevo and Copenhagen in 1965, Uzice 1966, Hastings 1967/68, Havanna 1969, Albena 1970, Kecskemét 1972, Brno 1975, Lublin 1976 and Dubna 1979.

He participated in seven Soviet championships from 1958 to 1966, reaching his best result in 1963, when he tied for 4-6th place (behind Stein, Spassky and Kholmov), then, in 1965 he also finished equal 4-6th place (behind Stein, Polugaevsky and Taimanov).

Until 1971, he was a trainer of Tigran Petrosian, assisted him preparing for the matches, including Petrosian’s world championship final victory of 1963. He was regarded as Moscow senior coach for many years, seeking and developing promising, talented chess players, such as Vassily Ivanchuk and Andrei Sokolov.

Although he was less prominent, his playing career stretched into the 1990s and beyond. At Hastings 1990/91 he won the tournament of the challengers, but he was, like Efim Geller, a chain-smoker and didn’t agree with the 1990 FIDE directive that banned smoking in tournament halls.

He was a famous commentator of the game from 1965 and correspondent for Pravda. His voice was often heard on Moscow radio and through the television during the 1970s and 1980s.

He won the Senior World Championship in 1966.

Suetin wrote many chess books, which concerned mostly the middle-games and the openings. Some of these: Modern Chess Opening Theory, Three Steps To Chess Mastery, A Contemporary Approach To The Middle-game, French Defence. His last book, Chess through the prism of time was published in Moscow, in 1998.

His wife was the Woman Grandmaster Kira Zvorykina and in 1951 their son, Aleksandr, was born. They lived in Belarus for some years, participating frequently in the national championship. Suetin won the championship six times; he and Zvorykina had the Men's and Women's titles contemporaneously in 1960.

According to the Chessmetrics, he had a score of 2701 as the highest Elo-point during his career.
