Peter Biyiasas

Biyiasas tied for 1st–4th places at Norristown 1973 at 7½/11, along with Kenneth Rogoff, Bruno Parma, and Herman Pilnik. He struggled in his first super-strong tournament, the 1973 Petropolis Interzonal, with 6½/17, for 15th place, as Henrique Mecking won. But he stayed on in Brazil for the São Paulo event, and placed respectably with 6½/13. Biyiasas won the British Columbia Diamond Jubilee Open in 1973, and repeated in 1974 and 1976.

Biyiasas made an excellent tied 3rd–4th at New York City 1977 with 8½/14, as Leonid Shamkovich and Andrew Soltis won. In the Canadian Zonal, Toronto 1978, he finished 2nd with 10/15, as Jean Hebert won. He was granted the Grandmaster title in 1978 for his strong New York and Buenos Aires Olympiad performances.

Biyiasas has been retired from competitive chess since 1985. He was married to Ruth Haring, a Women's International Master. They have three children, Lauren, Tina, and Theodore. His current FIDE rating is 2450. The site chessgames.com has a selection of 140 of his games.

Biyiasas won several tournaments in the San Francisco area, while visiting, and after moving there. These included four titles in the Carroll Capps Memorial (1981, 1982, 1983, and 1985); and four titles in the Arthur Stamer Memorial (1978, 1979, 1982, and 1984). These events were organized by the Mechanics Institute Chess Room. During a four-month period in 1981, Biyiasas played 17 five-minute games with Bobby Fischer, who was staying in his apartment at the time. Fischer, although he had been absent from competitive play for nine years, won all 17 games. Biyiasas said that he didn't think Fischer had lost anything in form, despite the layoff.

Biyiasas scored 7½/14 at Hastings 1978–79 to tie for 7th–10th places, as Ulf Andersson won. He won the 1979 Paul Keres Memorial tournament in Vancouver. He immigrated to the US in 1979, working in San Jose, California as an IBM computer programmer. Biyiasas scored 6½/15 at Hastings 1979–80 for 13th place, as Andersson won again. One of his strongest career results came in a very strong field at Wijk aan Zee 1980, where he made 7½/13 to tie for 4th–6th places, as Browne and Yasser Seirawan won. He scored an excellent 2nd place at Zrenjanin 1980. He played in the United States Chess Championship at Greenville 1980, finishing just below 50 per cent.

He notched a strong third place at the 1974 Pan American Chess Championship in Winnipeg with 11/15, as Walter Browne won. He tied with Kim Commons for the American Open title in 1974. He repeated as Canadian champion in the Zonal at Calgary 1975 with 12/15, half a point ahead of Kevin Spraggett. This earned him another Interzonal chance at Manila 1976, but he again found the company too strong, finishing with 6/19 for 17th place, as Mecking won again.

Biyiasas won the Zonal Closed Canadian Championship, Toronto 1972, with 12/17, half a point ahead of Lawrence Day and George Kuprejanov. For this, he earned the International Master title, as did Day and Kuprejanov. It marked an enormous leap in class for him in just one year, from second reserve on the Canadian student team to national champion.

Biyiasas was born in Athens, Greece, moved to Canada as a young boy, and grew up in Vancouver. He won the first of his four British Columbia chess championships in 1968; he would repeat in 1969, 1971, and 1972. He played in the 1969 Closed Canadian Chess Championship in Pointe Claire, and finished in the middle of the field, as Duncan Suttles won. Biyiasas was of National Master strength by this time. He represented Canada as second reserve on its bronze medal-winning team at the 1971 World Students' Olympiad in Mayagüez, Puerto Rico, where he scored 5/7 (+4 −1 =2). He graduated from the University of British Columbia in 1972 with a bachelor's degree in mathematics. He won the first of his three British Columbia Open titles in 1972, and repeated in 1976 and 1978.
