|Full name||Gyula Breyer|
|Born||30 April 1893
Gyula ("Julius") Breyer (30 April 1893 Budapest - 9 November 1921) was a Hungarian chess player and 1912 Hungarian national champion.
In 1912 Breyer won the Hungarian championship in Temesvar. In a 1920 tournament in Berlin he finished first (+6 −2 =1) ahead of Bogoljubov, Tartakower, Réti, Maróczy, and Tarrasch. Breyer had a plus record against Max Euwe (later world champion).
In 1921 Breyer set a new blindfold chess record by playing 25 games simultaneously. He also edited Szellemi Sport, a magazine devoted to chess puzzles, and composed at least one brilliant retrograde analysis study.
Heart disease cut short Breyer's promising chess career. He died in 1921 at the age of 28 in Bratislava. He was buried in Bratislava and after exhumation in 1987, was reburied in the Kerepesi Cemetery in Budapest.
Breyer was a leading pioneer of the hypermodern school of chess theory, which favoured controlling the centre with pressure from the flanks. He is noted for the maxim "after the first move 1.e4 White's game is in the last throes", although Breyer himself did not abandon that move. He was a friend of Richard Réti and an inspiration to other players.
He is most notably recognised for the Breyer Variation in the Ruy Lopez, which involves Black re-routing his queen's knight to d7 for increased flexibility (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.c3 d6 9.h3 Nb8 10.d4 Nbd7; see diagram). This line became fashionable in the 1960s, and a favourite of ex-world champion Boris Spassky. He is also recognised for the Breyer Variation of the Vienna Gambit (1.e4 e5 2.Nc3 Nf6 3.f4 d5 4.fxe5 Nxe4 5.Nf3 Be7), as well as the Breyer Gambit (1.e4 e5 2.f4 exf4 3.Qf3), a variation of the King's Gambit. He was an early adopter of the Slav Defense (1.d4 d5 2.c4 c6) at a time when the Queen's Gambit Declined (2...e6) was Black's most common response to the Queen's Gambit, and is credited with the Breyer Variation of the Slav (1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nbd2).
