O hráči
Overview
Iossif Davidovich Dorfman is a French-Ukrainian chess Grandmaster, author, and elite theorist born on May 1, 1952, in Zhytomyr, Ukrainian SSR, Soviet Union. Representing the French Chess Federation (FRA) since 1998, Dorfman achieved his peak classical FIDE rating of 2617 in July 2002. He holds the FIDE Grandmaster title (awarded in 1978) and is recognized as a FIDE Senior Trainer (awarded in 2004). Dorfman’s primary competitive identity is that of a top-tier classical tournament player, national champion, and one of the chess world's most influential strategic coaches. He famously served as a principal second to World Champion Garry Kasparov during his first four World Championship matches against Anatoly Karpov, and subsequently authored The Method in Chess (2001), a seminal work on positional evaluation. He has also coached several world-class players, including Etienne Bacrot and Maxime Vachier-Lagrave.
Biography & Major Career Milestones
Dorfman developed his chess skills in the highly competitive Soviet training system. He first made a major impression on the national stage at the 1975 USSR Chess Championship (43rd URS-ch) in Yerevan, finishing in thirteenth place. The following year, he won the USSR Championship First League in Tbilisi with an undefeated score of +6 =11, finishing 1½ points clear of the field to qualify for the premier national tournament.
His career peak as a player occurred at the 1977 USSR Chess Championship in Leningrad. Dorfman finished in joint first place alongside Boris Gulko with a score of 9.5/15 (+4 =11), finishing half a point ahead of three former World Champions: Tigran Petrosian, Lev Polugaevsky, and Mikhail Tal. A subsequent six-game playoff match between Dorfman and Gulko to decide the title ended in a draw (+1 -1 =4), resulting in both players sharing the prestigious title of Soviet Champion. Following this landmark result, Dorfman was awarded the International Master title in 1977 and the Grandmaster title in 1978.
During the late 1970s and 1980s, Dorfman competed extensively in high-level international tournaments:
- In 1978, he finished second to Vasily Smyslov at São Paulo and tied for second at Polanica Zdrój.
- In 1979, he shared first place at Jakarta (with Eugenio Torre and Yuri Averbakh) and tied for third at Manila.
- He took clear first place at Zamárdi in 1980.
- He won at Warsaw in 1983 with a score of +6 =8.
- In 1984, he tied for first at Lvov.
- He secured sole first place at Moscow in 1985.
- In 1986, he tied for fifth at Minsk.
Following the collapse of the Soviet Union, Dorfman relocated to France in 1990 and gained French citizenship in 1998. In his debut appearance at the French Chess Championship in Meribel in 1998, he won the national title. Throughout his career, Dorfman's deep analytical reputation made him a sought-after second. He made monumental theoretical contributions while working in Garry Kasparov’s camp from 1984 to 1990, and later directed the competitive growth of top French players.
Elite Team & Event Performance
Dorfman represented France at three Chess Olympiads, exhibiting remarkable defensive solidity:
- 33rd Chess Olympiad (1998) in Elista: Represented France on Board 2, scoring +3 –0 =6.
- 35th Chess Olympiad (2002) in Bled: Represented France on Board 2, scoring +1 –1 =8.
- 36th Chess Olympiad (2004) in Calvià: Represented France on Board 3, scoring +2 –0 =8.
Playing Style, Material Tendencies & Endgame Profiling
Dorfman is classically defined as a highly refined positional player, structural purist, and technical strategist. His playing style is fully aligned with the systematic approach he codified in The Method in Chess. This approach divides decision-making into identifying "critical positions" and drawing up a "static balance" using a regressive scale of four essential elements:
- King Position: Dorfman views king safety as the ultimate static factor. His play is highly prophylactic; he routinely prioritizes securing his own king or exploiting structural weaknesses around the opponent's king over immediate material gain.
- Material Correlation: He carefully assesses minor-piece imbalances. He posits that a bishop-for-knight exchange is generally justified only if the pawn structure is completely fixed. He historically favors the bishop pair in open or semi-open positions and values the long-term static advantage of a rook-and-bishop tandem against a rook-and-knight.
- Queen Exchanges: Dorfman treats the presence or absence of queens as a critical structural pivot, directly linking the exchange of queens to the structural evaluation of king safety.
- Pawn Formation: He systematically evaluates pawn islands, doubled/tripled pawns, central and queenside majorities, isolated or backward pawns, and color-complex weaknesses.
Dorfman’s handling of space and pawn breaks is guided by his theory of "independent evolution". When his evaluation shows a superior static balance, he avoids forcing the play, choosing instead to slowly improve his pieces, restrict his opponent’s counterplay, and accumulate small advantages. Conversely, if his static balance is inferior, he immediately seeks dynamic, high-energy pawn breaks to contact the opponent's forces, generate tactical complications, and alter the pawn structure before his opponent can convert long-term static advantages.
In worse positions, Dorfman is a resilient defender who relies on fortress construction and the exchange of key pieces to transition into defensible endgames. His endgame technique is exemplary, particularly in rook-and-pawn endings and opposite-colored bishop structures, where his precise calculation of static pawn majorities and defensive barriers allows him to efficiently convert narrow advantages or hold theoretically drawn endgames.
Opening Repertoire & Theoretical Move Orders
Dorfman’s opening choices reflect his positional preference for healthy pawn structures, space advantages, and predictable, long-term static plans.
1. As White
Dorfman's primary first-move choices are 1.d4, 1.c4, and 1.Nf3, steering games away from early, chaotic tactical skirmishes toward structured positional battles.
Against 1...Nf6 setups, Dorfman’s premier weapon is the Catalan Opening. He utilizes the kingside fianchetto to exert long-term pressure on the queenside while keeping his king highly secure:
In the English Opening (1.c4), when facing 1...e5, Dorfman adopts symmetrical four-knights setups with a kingside fianchetto to establish stable control over the central squares:
Against the King's Indian Defense, he routinely plays classical systems, using White's central space advantage to restrict Black's counterplay:
2. As Black
Against 1.e4, Dorfman relies heavily on the French Defense and the Sicilian Defense, prioritizing structural resilience and counter-attacking potential.
In the French Defense, he frequently employs Classical and Rubinstein variations, accepting a slightly passive light-squared bishop in exchange for a highly robust pawn structure:
Against 1.e4, he also plays the Sicilian Kan, keeping a flexible pawn structure that minimizes early targets for White:
Against the Ruy Lopez, Dorfman has utilized the solid Anderssen Variation to establish early queenside stability:
Against 1.d4, Dorfman primarily deploys the Nimzo-Indian and Bogo-Indian Defenses, striving to trade black-squared bishops for white knights to establish favorable minor-piece imbalances:
He also routinely uses the Queen's Indian Defense to contest control of the central e4 and d5 squares from the flank:
For symmetrical d-pawn struggles, Dorfman utilizes the semi-Slav or Slav Defense to maintain a solid, compact pawn skeleton:
