Alexander Mikhailovich Chernin (Russian: Александр Михайлович Чернин; born March 6, 1960 in Kharkiv, Ukraine) is a prominent chess master and a former Soviet Champion now living in Hungary.
As a youth, he frequently succeeded in tournaments and climbed rapidly through the junior rankings to participate at the very highest level. At Skien in 1979, he entered the World Junior Championship and finished runner-up to Yasser Seirawan. A short while later (January 1980), he played in the European Junior Championship at Groningen and won the event (ahead of Zurab Azmaiparashvili).
These prestigious successes soon led him to an International Master title and more importantly, laid the foundation stones for his continued development over the next few years. There were many tournament victories, either outright or shared, including Irkutsk 1980, Copenhagen 1984 (and 1986 with Vasily Smyslov), Stary Smokovec 1984, Polanica Zdroj 1988, Prague 1989 and Marseilles 1990 (with Evgeny Bareev). Also of note were the second places achieved at Cienfuegos 1981 and Reggio Emilia 1986/7.
The pinnacle of his playing career undoubtedly occurred in 1985, when he became a Grandmaster, won the Soviet Championship (jointly with Viktor Gavrikov and Mikhail Gurevich) and scored well in the Gammarth (Tunisia) Interzonal for a place in the Montpellier Candidates Tournament. Unfortunately, his World Championship Candidacy went no further, as he could only manage a mid-table finish. He was however a double gold medal winner in the same year, taking team and individual honours at the inaugural World Team Championship, held in Luzern, where he represented the USSR.
Into the 1990s, Chernin was still performing well in international competition; first at Dortmund 1990 (ahead of Boris Gelfand) with further successes to follow at Buenos Aires 1992, Gothenburg 1996 and Aubervilliers 1996 (the latter, a rapid event).
Chernin relocated to Budapest in 1992 and became a Hungarian national a year later. He has represented his adopted country many times; for instance at the Olympiads of 1994 and 1996, but also at three European Team Chess Championships, the latest being in 1999, when he won a team silver medal.
Into the new millennium, he has played less often, but was joint winner of the 2001 Corsica Masters, losing out to Viswanathan Anand in the final play-off game for the champion's title. He is also involved in coaching, his best known student being the young Italian-American master Fabiano Caruana. In 2004 he was awarded the title of FIDE Senior Trainer.
Alexander Chernin is a renowned theorist and has written analytical articles for New In Chess amongst other publications. In the chess openings arena, he is a noted expert on the Pirc Defence and in 2001, co-authored a repertoire book with Lev Alburt, named Pirc Alert!.
