Duncan Suttles

Duncan Suttles (born 21 December 1945) is a Grandmaster of chess who was the strongest Canadian player between the eras of Abe Yanofsky and Kevin Spraggett. He is one of the few over-the-board grandmasters who also holds the title of Grandmaster of International Correspondence Chess. Suttles has been inactive in over-the-board play since the mid-1980s. He currently serves with the software firm Magnetar Games, as president and chief technologist.

Early years

Suttles was born in San Francisco, California, but moved to Canada as a child. He was of National Master strength by his mid-teens, which was unusual for Canadian chess at that time. His early mentor was mathematician and master Elod Macskasy.''Chess on the Edge'', by Bruce Harper and Yasser Seirawan, Chess'n Math Association publishers, Montreal 2008.

Suttles made his first appearance in the Closed Canadian Chess Championship at Brockville, 1961, at age 15, and scored 3/11., the Duncan Suttles results file. Suttles won the British Columbia Championship in 1963 and 1966. In his second Closed, he scored 8½ from 15 games at Winnipeg 1963, finishing just above the middle of the strongest and youngest field yet seen in a Canadian final. Suttles tied for 3rd–5th places in the 1964 Canadian Open Chess Championship in Toronto, and as the top junior, qualified for the 1965 Junior World Chess Championship.''Chess on the Edge'', by Bruce Harper and Yasser Seirawan, Chess'n Math Association publishers, Montreal 2008, p. xii. He took part in The Gijon International Chess Tournament (1965), achieving 2nd behind Luis Bronstein. At home in Vancouver for the 1965 Canadian Championship, Suttles scored 8/11 and finished second, behind eight-time champion Daniel Yanofsky. As a dual Canadian-American citizen, Suttles was also eligible for the United States Championship, New York City 1965–66, in which he finished last with 2½/11, an event won by Bobby Fischer.

Suttles attended the University of British Columbia, and represented the school in inter-university chess competition. He earned his undergraduate degree in mathematics, and began doctoral-level studies, but did not complete his PhD.

Represents Canada

Suttles represented Canada at the Junior World Chess Championship, Barcelona, 1965, but was drawn into a strong preliminary group which included the eventual winner, Bojan Kurajica, and could only score 1½/4, failing to advance to the finals. Suttles did manage to win the B final, ahead of Raymond Keene. Suttles represented Canada in the qualifying Interzonal event for the World Chess Championship at Sousse, 1967, scoring 9½/21 for 15th place. Suttles won the Canadian Chess Championship held at Pointe-Claire 1969, after a playoff match with Zvonko Vranesic in Toronto, which Suttles won by 2½–1½. He took another crack at the Interzonal level at Palma de Mallorca, 1970, scoring 10/23 for a tied 15–16th place, but he did not qualify for the final Candidates' matches that would choose the title challenger.

Olympic stalwart

Suttles appeared at age 18 on the Canadian Olympiad team for Tel Aviv, 1964, for the first of his eight selections, including six in a row, over a period of 20 years. He usually played a large number of games in these team events, close to the maximum. Here are his complete results; his totals for Canada in Olympiads are: (+49 −30 =43), for 57.8 percent. He also played board one for Canada on its bronze medal–winning team at the 1971 Student Olympiad.

* Tel Aviv 1964: 1st reserve, 5½/10, +4 −2 =3;
* Havana 1966: 4th board, 10/18, +8 −5 =5;
* Lugano 1968: 2nd board, 11½/17, +7 =9 −1;
* Siegen 1970: 2nd board, 8/16, +3 −3 =10;
* Mayagüez Student Olympiad 1971: 1st board, 6½/11, +6 −4 =1, team bronze;
* Skopje 1972: 1st board, 9½/17, +6 −4 =7;
* Nice 1974: 1st board, 10½/19, +8 −6 =5;
* Valletta 1980: 2nd board, 3/8, +2 −4 =2;
* Thessaloniki 1984: 1st board, 5/11, +4 −5 =2.

Grandmaster

Suttles became a Canadian citizen in 1966, and married his wife Dobrila in 1968.

Suttles was already of Grandmaster strength by 1968, and in fact qualified for the grandmaster title at the Lugano Olympiad. However, he was denied the title on the basis of a technicality, that he had played (and won) one more than the required number of games in the event. Instead, Suttles settled for the International Master title, earned in 1967 at the Sousse Interzonal. He finally achieved the Grandmaster title at the San Antonio tournament of 1972, gaining the last half-point he needed against Armenian Grandmaster and former world champion Tigran Petrosian.

He won the Canadian Open Chess Championship at Ottawa 1973. He also won the 1973 '' La Presse'' Open in Montreal. Suttles tied for first place in the U.S. Open Chess Championship at Chicago 1973, scoring 10/12 and defeating GM Walter Browne in the last round.''Chess on the Edge'', by Bruce Harper and Yasser Seirawan, Chess'n Math Association publishers, Montreal 2008, pp. 216–19. Suttles placed clear second in the 1974 Canadian Open Chess Championship in Montreal with 9½/11, losing only to the winner Ljubomir Ljubojević.

He won the Western Canadian Open, Vancouver 1981, defeating Tony Miles and Yasser Seirawan in the final two rounds. He won his final Canadian event, the 1984 Vancouver Futurity.

While taking a break from over-the-board chess, he won a pre-computer era high level correspondence chess tournament, the Heilimo Memorial, played from 1978–1981. He was awarded the title of International Grandmaster of Correspondence Chess in 1982, making him one of the very few players to hold GM titles both for over the board chess and chess by correspondence.

Playing style and legacy

In his youth, Suttles was strongly influenced by Aron Nimzowitsch, and became well known due to his preference for hypermodern openings. He was perhaps the world's leading advocate of the Modern Defence from the mid-1960s, and showed that this line, a universal defence against any White opening move, was fully playable, which had not been the case before his time. The line was nicknamed the 'Rat', for the Black fianchettoed bishop which kept dodging around in its holes! As White, Suttles favoured 1.e4, with a predilection for the Closed Variation against the Sicilian Defence, and the baroque Vienna Game after 1.e4 e5. He occasionally played the English Opening (1.c4) as well. By the early 1970s, he was frequently opening with 1.g3 as White, aiming for a reversed Modern Defence, another new opening idea. His unique skills – such as the avoidance of main opening lines, use of a defensive kingside fianchetto, development of knights to unusual squares, and sudden eruption of tactics – are well illustrated by the selection of games listed below, which are all characteristic of Suttles at his best.

Suttles was the leader in a group of strong young British Columbia masters mentored by the veteran Macskasy. The players competed hard head-to-head, but also worked together, learned from each other, and employed original playing styles to largely dominate Canadian chess for the better part of a decade. Other members of this group from the late 1960s included Peter Biyiasas, Bruce Harper, Jonathan Berry, and Robert Zuk.

In the book ''The World of Chess'' (1974), authors Anthony Saidy and Norman Lessing described Suttles as the 'most original strategist since Nimzowitsch'.

A significant project, entitled ''Chess on the Edge'', includes the largest annotated collection of his games, more than 600 in all. Simultaneous publication of the three volumes took place in March, 2008, with the publisher being the Chess'n Math Association. FM Bruce Harper, one of Suttles' students, led the effort, with assistance from GM Yasser Seirawan, Dutch IM Gerard Welling, and GMC Jonathan Berry.

Another Modern execution of a strong European; the game is finally decided after a very long endgame.

Duncan Suttles vs Borislav Ivkov, Belgrade 1969, Modern / Hungarian Opening (A00), 1–0
One of the first games for this new variation, and it turns out successfully for White.

The rising star Browne, an eventual six-time American champion, learns painfully about Suttles' exploitation of weak squares.

Duncan Suttles vs Pal Benko, Hastings 1973–74, Modern / Hungarian Opening (A00), 1–0
It was Benko himself who had first introduced this variation in the early 1960s, but here Suttles shows off a few new twists.

Miles, after losing this game, would go on to use this variation himself with success.

Yasser Seirawan vs Duncan Suttles, Vancouver 1981, English Opening (A21), 0–1
Seirawan was one of the world's top young players, and he would develop a style which resembled that of Suttles.
