Vladimir Liberzon

 Vladimir Mikhailovich Liberzon (ולדימיר מיכאילוביץ' ליברזון; Влади́мир Миха́йлович Либерзо́н; 23 March 1937, in Moscow – 4 August 1996) was a Russian-born Israeli chess grandmaster.

Biography
Liberzon played in several Soviet championships, his best result being fourth at the 36th Championship, Alma-Ata 1968/69. Other results were less notable; his first entry led to a lowly finish at Tbilisi 1966/67, whereas he achieved solid mid-table performances at Moscow 1969 and at Riga 1970.

In tournaments he was first in Moscow (Central Chess Club-ch) in 1963, 1964, and 1965, fourth at Kislovodsk 1964, fifth at Yerevan 1965, second at Leipzig 1965, first at Zinnowitz 1967, first at Debrecen 1968, second at Amsterdam 1969, third at Dubna 1971 and third equal at Luhačovice.

Liberzon was the first grandmaster from the Soviet Union who was allowed to emigrate to Israel in 1973. Consequently, he became Israel's first grandmaster. He won the Israeli Championship in 1974.

Having transferred nationality, he continued to score well in international competitions, finishing first at Venice 1974, first at Lone Pine 1975, second equal at Netanya 1975, second equal at Reykjavík 1975, first equal at Beer-Sheva 1976, first equal at Netanya 1977, 3rd at Amsterdam 1977, first equal at Lone Pine 1979, and fourth equal at Beer-Sheva 1984.

Liberzon played for Israel in four Chess Olympiads.
 * In 1974, at first board in 21st Olympiad in Nice (+4 –3 =8);
 * In 1976, at first board in 22nd Olympiad in Haifa (+2 –2 =6);
 * In 1978, at second board in 23rd Olympiad in Buenos Aires (+1 –2 =6);
 * In 1980, at first board in 24th Olympiad in La Valletta (+2 –2 =5).

He was awarded the International Master (IM) title in 1963, and Grandmaster (GM) title in 1965.

According to William Hartston, in The Independent, Liberzon was known for his disciplined professionalism and this made him one of the most consistent performers on the tournament circuit of the 1960s and 70s. His move to Israel was in all likelihood a catalyst for the great chess advances that occurred there in subsequent years. In terms of memorable games, Hartston cites the following effort, from Moscow 1963. It is the rarest of lessons in attacking chess, given that his opponent is none other than tactical maestro and former world champion, Mikhail Tal. Most instructively, Liberzon makes the opposite-coloured bishops work in his favour.
