Nc6 is sometimes called the Kevitz-Trajkovic Defence[, alternatively the Black Knights' Tango or Mexican Defence. In the Nimzowitsch Defence, 1.e4 Nc6, the Kevitz Variation continues 2.d4 e5. In the 1940s, Kevitz analyzed a new idea in the Ruy Lopez, Marshall Attack, after 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 d5 9.exd5 Nxd5 10.Nxe5 Nxe5 11.Rxe5 c6 12.Bxd5 cxd5 13.d4 Bd6 14.Re3, which prepares 15.h3 in the event of 14...Qh4. Kevitz was respected by his chess rivals as an original player, thinker, and analyst. He was active in tournament play until age 78 in 1980, the year before his death.

Johannes Hermann Zukertort was born on the 7th of September 1842 in Lublin, Poland. His early chess career had a lot to do with Adolf Anderssen against whom he played two matches. He lost in Berlin 1868 (+3, =1, -8) and won in 1871 (+5, =0, -2) and it was on the strength of this second match that he was invited to play in the London tournament of 1872. He finished in 3rd place behind Wilhelm Steinitz and Joseph Henry Blackburne. He lost a short match against Steinitz after this and became a naturalized British citizen in 1878. The peak of his career came with his
victory in the London tournament of 1883, 3 points ahead of Steinitz and 5 1/2 points ahead of Blackburne who came 3rd. In 1886 he and Steinitz played the First World Championship Match. The strain proved too much and Zukertort not only lost the match (+5, =5, -10) but his health was seriously affected. He passed away from a cerebral haemorrhage after playing a game in Simpson's Divan in London in 1888. In Breslau Zukertort met the leading chess player Adolf Anderssen and studied with him. Among many other notable matches he played with Anderssen, he defeated him in 1866, lost in 1868 by a score of eight wins, three losses, one draw, and finally defeated him convincingly (5-2; no draws) in a match in 1871.[4][5] In 1867 he moved to Berlin and in 1872 to London. In that year, he played Wilhelm Steinitz in London, losing 9-3 (7 losses, 1 win, 4 draws).[5] Although Zukertort lost both his matches against Steinitz, he proved that he was superior to other opponents throughout the late 1870s and early 1880s.[6] During this period top-class tournaments were rare[7] and Zukertort's best performances were mostly in matches, notably against Anderssen in 1871 and Joseph Henry Blackburne in 1881 (6 wins, 2 losses, 5 draws).[6][8] Nonetheless Zukertort was one of the most successful tournament players of his time: 3rd behind Steinitz and Blackburne at London, 1872; 1st at Cologne and 2nd at Leipzig in 1877; tied for 1st with Simon Winawer at the Paris International Chess Congress in 1878 and beat Winawer in the play-off; 2nd at Berlin in 1881, behind Blackburne; tied for 4th at Vienna in 1882; 1st at London in 1883, 3 points ahead of Steinitz.[3] Zukertort's win in the London 1883 chess tournament was his most significant success: he won his games against most of the world's leading players, scoring 22/26, and he finished 3 points ahead of Steinitz, who was second with 19/26.[9] This tournament established that Steinitz and Zukertort were clearly the best two players in the world, and led to the World Chess Championship match between these two.[10] The 1886 World Chess Championship match lasted from 11 January to 29 March 1886. After building up a 4-1 lead Zukertort wilted, lost 4 of the last 5 games and lost the match by 1212-712.[11] After this defeat, Zukertort's health suffered and he was a greatly weakened player for the remaining two years of his life. Diagnoses of his ailments include rheumatism, coronary heart disease, kidney problems, and arteriosclerosis. His results after the 1886 match declined steeply: 7th at London and 3rd at Nottingham in 1886; 15th at Frankfurt and 4th at London in 1887; lost a match in 1887 against Blackburne (1 win, 5 losses, and 8 draws); 7th at London in 1888.[3] Poor health and lack of physical stamina appeared to be one of Zukertort's two long-term weaknesses: some commentators attributed to illness the severity of his defeat in the 1872 match against Steinitz;[12] in the 1883 London tournament he won 22 of his first 23 games, enough to give
him an uncatchable lead, but lost his last 3 games; and he initially built up a 4-1 lead against Steinitz in 1886, but then his performance sharply deteriorated.[13][11] His other weakness was that, while no one had greater attacking flair, Zukertort never approached Steinitz' understanding of positional play and Steinitz often out-maneuvered him fairly simply.[7] Unlike the majority of attacking players, Zukertort preferred openings such as 1. c4 and 1. Nf3 that were closed or semi-closed and offered the possibility of transpositionsin fact in the early 1880s 1. Nf3 was known as "Zukertort's Opening", 40 years before it became known as the Reti Opening.[7][14] In his prime Zukertort also excelled at playing while blindfolded. In 1876, he played sixteen games simultaneously while blindfolded, winning twelve and losing only one.[3] Later life Zukertort died 20 June, 1888, in London from a cerebral hemorrhage after playing a game in a tournament Simpson's Divan, which he was leading at the time.[3] He is buried in Brompton Cemetery in London. Trivia It is said that Steinitz and Zukertort, present at the same dinner party, both rose in response to a toast to the "greatest chess-player in the world". Research by Edward G. Winter suggests that this story has been embellished.[15] [Event "Tnmt, London"][Site "Tnmt, London"][Date "1883.??.??"][EventDate "?"][Round "?"][Result "1-0"][White "Johannes Zukertort"] [Black "Joseph Henry Blackburne"][ECO "A13"][WhiteElo "?"][BlackElo "?"][PlyCount "65"]1. c4 e6 2. e3 Nf6 3.
