Borislav Ivkov

Ivkov earned his National Master title in 1949 at age 16, by placing shared 4th–7th in the Yugoslav Championship at Zagreb, with 11/19; the winner was Svetozar Gligorić. Ivkov earned his first international event opportunity at Bled 1950, sharing 5th–6th places with 7½/14; the winner was Miguel Najdorf. In this tournament, which featured some of the world's best players, Ivkov defeated well-known stars such as Hermann Pilnik, Milan Vidmar Jr., and Vasja Pirc. After this impressive debut, he was selected to represent Yugoslavia in team matches against the United States and the Netherlands in 1950 and against West Germany in 1951. Ivkov won the inaugural World Junior Chess Championship in 1951 at Birmingham; this tournament was established for players under age 20. He continued his progress with two solid showings in Yugoslav Championships: at Sarajevo 1951 he tied 10th–12th places with 9½/19 (winner Braslav Rabar), and at Belgrade 1952 he tied 7th–9th places with 10/19 (winner Petar Trifunović). At Opatija 1953, Ivkov scored 10/17 for a shared 4th–6th place; the winner was Aleksandar Matanović. Ivkov was still eligible by age in 1953 to try to repeat his World Junior success; at Copenhagen he won his preliminary group with 7/9, but scored only 3½/7 in the finals to place tied 3rd–4th, as Oscar Panno and Klaus Darga tied at the top. == Rapid rise ==

Ivkov shared 4th–5th place (with Petrosian) at Belgrade 1954 with 11½/19; this was his strongest event to date, the first Yugoslav event to welcome Soviet players following the end of World War II. The winner was David Bronstein. Ivkov earned the International Master title. Ivkov broke through into the group of the world's elite players with two brilliant results in strong tournaments in Argentina. He won at Mar del Plata 1955 with 11½/15, ahead of Najdorf, Gligoric, Szabo, Luděk Pachman, Panno and Pilnik. Then he won again at Buenos Aires 1955 with 13/17, ahead of Gligoric, Pilnik, László Szabó, Bisguier, Luděk Pachman, Rosseto, Panno and Donner. In the Yugoslav Championship at Novi Sad 1955, Ivkov had his best national result to date with a shared 3rd–4th place on 10½/17; the winner was Karaklajic. Then at Zagreb 1955, he tied 2nd–3rd places with Matanovic on 12½/19; the winner was Vasily Smyslov. Ivkov earned his Grandmaster title in 1955. At Hastings 1955–56, Ivkov finished 3rd with 6½/9 behind winners Viktor Korchnoi and Friðrik Ólafsson. He represented Yugoslavia in the World Students' Olympiad at Uppsala 1956; on board two he scored 5/9 (+2 =6 −1), and Yugoslavia won the team bronze medals. == National team stalwart ==

Ivkov earned the first of his 12 selections to the Yugoslav Olympiad team in 1956, and was a member of the national team continuously through 1980 with a personal score of 82 wins, 13 losses and 76 draws (70.2%). This was during the golden age of Serbian chess, a period when Yugoslavia (led by Serbian grandmasters like Gligorić, Ivkov, Trifunović, Matanović, Matulović, Ljubojević etc.) was usually among the top three chess countries. He won a total of ten team medals and four board medals during his career. • Moscow 1956: board 3, 12/16 (+9−1=6), board silver, team silver; • Munich 1958: board 3, 9½/15 (+7−3=5), team silver; • Leipzig 1960: board 3, 12/16 (+9−1=6), board bronze, team bronze; • Varna 1962: board 4, 13½/16 (+11−0=5), board gold, team silver; • Tel Aviv 1964: board 2, 11½/16 (+8−1=7), team silver; • Havana 1966: board 2, 10/15 (+8−3=4); • Lugano 1968: board 2, 9/14 (+5−1=8), team silver; • Siegen 1970: board 2, 10/13 (+7−0=6), board gold, team bronze; • Skopje 1972: board 2, 12/18 (+6−0=12), team bronze; • Nice 1974: board 3, 12/17 (+8−1=8), board 4th, team silver; • Buenos Aires 1978: board 4, 3/7 (+1−2=4); • Valletta 1980: board 2, 5½/8 (+3−0=5), team bronze. With 14 team and board medals at Chess Olympiad, Ivkov set an all-time record among Serbian and Yugoslav players and become the fifth-most decorated player in the Olympiad history (tied with Garry Kasparov) behind Mikhail Tal (15), Paul Keres (15), Tigran Petrosian (16) and Vasily Smyslov (17). At the same time, his 10 team medals are the second most all-time (tied with Petrosian) behind Svetozar Gligorić's 12. Ivkov made his first appearance at the European team level in the inaugural event at Vienna 1957, and was chosen on five further occasions. He won four team medals and three board medal in Euroteams events. According to the site olimpbase.org, Ivkov's totals in Euroteams play are (+10 =29 −4), for 57 per cent. • Vienna 1957: board 3, 3½/6 (+2−1=3), team silver; • Hamburg 1965: board 1, 5/10 (+2−2=6), team silver; • Kapfenberg 1970: board 2, 4/7 (+2−1=4); board 4th, team 4th • Bath 1973: board 2, 4½/7 (+2−0=5), board gold, team silver; • Moscow 1977: board 6, 4/7 (+1−0=6), board silver, team bronze; • Skara 1980: board 3, 3½/6 (+1−0=5), board silver. Ivkov also participated in 16 editions of the USSR versus Yugoslavia matches from 1956 to 1979, more than any other Yugoslav or Soviet player. == Yugoslav Champion, international victories ==

Ivkov narrowly missed becoming Yugoslav champion at Sombor 1957 when he scored 14/22 to share 2nd–4th places behind Gligoric. But he had a setback at the 1957 Wageningen Zonal tournament, failing to qualify for the Interzonal stage by making only 8½/17 for 9th position. He recovered with his first Yugoslav title at Sarajevo 1958, sharing the title with Gligoric on 12½/19. This victory set off a string of tournament triumphs over the next five years. Ivkov won at Sarajevo 1958 with 7/11. He won at Belgrade 1959 by 2½ points with 9/11. In a strong field at Dresden 1959, he shared 3rd–4th places with 10/15 behind winners Efim Geller and Mark Taimanov. Ivkov shared the win at Lima 1959 with Pachman on 10½/13, and again shared the win at Santiago 1959 with Pachman. At Mar del Plata 1959, he shared 3rd–4th places with Bobby Fischer, behind winners Pachman and Najdorf. Ivkov shared the victory at Beverwijk 1961 with Bent Larsen on 7½/9. At Belgrade 1962, he was second on 8/11 behind Gligoric. At Havana 1962, Ivkov scored 14½/21, but had to content himself with sixth place, as Najdorf won. Ivkov qualified from the 1963 Halle Zonal tournament into his first Interzonal the next year. At Halle, he tied 3rd–4th places with 12/19, then defeated Karl Robatsch by 2–0 in a playoff for the last berth. At Beverwijk 1963, he shared 3rd–5th places with 11/17, as Jan Hein Donner won. Ivkov won his second Yugoslav title at Zenica 1964 with 15/21, shared with Mijo Udovčić. At Havana 1963, he scored very well with 15½/21, but this was only good enough for a shared 5th–6th place, as Korchnoi won. Ivkov shared 2nd–3rd places at Belgrade 1964 on 11½/17 behind Boris Spassky. At Beverwijk 1964, he was 4th with 10/15 behind Estonian winners Paul Keres and Iivo Nei. Then at Sarajevo 1964, he finished 3rd with 9½/15 as Lev Polugaevsky won. == World Championship Candidate ==

Ivkov qualified from the 1964 Amsterdam Interzonal to the Candidates' matches the next year, with a score of 15/23. But he lost his first-round/quarterfinal Candidates' match at Zagreb to Bent Larsen by 5½–2½. He played at the Interzonal level four more times, but did not advance further. He narrowly missed moving on at age 46 in 1979. • 1967 Sousse: 11/21, 11th out of 22; • 1970 Palma de Mallorca: 10½/23, 14th out of 24; • 1973 Petrópolis: 9/17, tied 9th–10th out of 18; • 1979 Rio de Janeiro: 9½/17, 6th out of 18.

At Capablanca Memorial in Havana 1965, Ivkov shared 2nd–4th places with Geller and Fischer, and defeated Fischer for the second time in their game; the winner was Smyslov. In fact he was leading before he blew an easily won game against Gilberto Garcia, the latter of whom had lost most of his games at that point; this would have been his greatest victory. Ivkov shared 2nd–3rd places in the Yugoslav Championship at Titograd 1966 with 11½/18 as Gligoric won. Then at Zagreb 1965, Ivkov scored perhaps his most impressive career victory, sharing the title with Wolfgang Uhlmann on 13½/19, ahead of World Champion Tigran Petrosian, Lajos Portisch, Larsen, and Bronstein. Ivkov won at Venice 1966 with 5/7. He ended 4th at Beverwijk 1966 on 10/15 as Polugaevsky won. Ivkov won at Eersel 1966 with 4/5.

He tied 2nd–3rd places at Bauang, La Union 1973 on 6½/9 behind Kavalek. Then he shared the title at Amsterdam 1974 on 10/15 with Vlastimil Jansa and Vladimir Tukmakov. == Later years ==

Ivkov fell out of the top 40 after 1975, and appeared less frequently in major events. But he still had some notable results later in his career. He was 2nd at Štip 1977 with 8½/13, behind Hort. At Bor 1984, he shared 2nd–4th places with 8½/13 behind winner Slobodan Martinovic. He won the traditional Capablanca Memorial tournament, played at Cienfuegos in 1985 with 10/13.

Ivkov tied 2nd–4th places in the 25th anniversary Paul Keres Memorial at Vancouver with 7½/10, behind winner Vladimir Epishin. He was awarded the International Arbiter title in 1986.

With his wife Olga María Kesic, Ivkov had a son and a grandson. With his second wife, Branka Vujnovic, he had two children. Ivkov died on 14 February 2022, at the age of 88. == Legacy and playing style==

Ivkov defeated five World Champions: Vasily Smyslov, Mikhail Tal, Tigran Petrosian, Bobby Fischer, and Anatoly Karpov. He also scored wins over most of the top players of his era, except Mikhail Botvinnik and Paul Keres. Head-to-head, he was dominated by such stars as Gligoric, Tal, and Larsen. Ivkov's style is classical, and he opened regularly with both 1.e4 and 1.d4 during his peak years, making him problematic to prepare for. As Black, he replied to 1.e4 with the Sicilian Defence, the French Defence, and 1...e5, showing a wide repertoire which he handled well. While usually tending toward solid positional play, Ivkov could switch to fierce tactics when given the opportunity. During his peak years, he played in many high-class tournaments, and was almost always near the top of the table. == Notable games ==
