Early life
Day first played for Canada in the 
Chess Olympiad in 1968 on the first reserve board (+3,=1,-8) at 
Lugano,
 his first of 13 appearances, which is a Canadian record. Day played 
board three for Canada (scoring +7,=1,-2) on the bronze medal team at 
the 
World Students' Chess Olympiad, 
Mayagüez 1971. He graduated from 
Carleton University in 1972 with a degree in 
English Literature, worked for the magazine 
Chess Canada for a time, and then became a professional player. He earned his 
International Master title at the Zonal 
Canadian Chess Championship, 
Toronto 1972.
Canadian stalwart
He has been winning tournaments in Canada and North America since the
 late-1960s. He won the 1969 U.S. Junior Open. His biggest paycheck was 
for topping the field at the 1980 World Open. Day won three 
Canadian Open Chess Championships (1976, 1980, 1988). He won the Quebec Open Chess Championship three times (1974, 1975, 1979).
[1] He won the 1991 Closed 
Canadian Chess Championship. He tied for first place at the 1999 
North Bay
 International Open, the last of that series of six annual excellent 
tournaments held there. So far he has won the Toronto City Championship 
Cup five times (1977, 1980, 1983, 1984, 1995). Day has won several dozen
 weekend Swiss format tournaments in 
Ontario since the late 1960s.
Day's Olympiad appearances for Canada have spanned 30 years, from 
1968–1998, according to the comprehensive Olympiad site olimpbase.org.

 In his later years, during the 1990s, he several times volunteered at 
the last minute to fill in for players who were unable to go because of 
unforeseen circumstances. Day played at 
Skopje 1972 as second reserve (+2,=5,-3); 
Nice 1974 as first reserve (+5,=5,-1); 
Haifa 1976 as second board (+2,=6,-2); 
Buenos Aires 1978 as third board (+6,=3,-2); 
La Valletta 1980 as second board (+5,=4,-2); 
Lucerne 1982 as fourth board (+5,=2,-5); 
Thessaloniki 1984 as third board (+3,=5,-2); 
Dubai 1986 as third board (+8,=0,-3), winning the bronze medal; 
Manila 1992 as first reserve (+0,=2,-4); Moscow 1994 as fourth board (+3,=3,-3); 
Yerevan 1996 as first reserve (+6,=3,-2); and finally at 
Elista
 1998 as first reserve (+3,=0,-4). His totals for Canada in Olympiad 
play are: +51,=39,-41, in a total of 131 games, which is the second most
 by a Canadian, behind only 
Daniel Yanofsky's
 141. Canada made its best Olympiad results so far in 1976 with eighth 
place, eleventh place in 1978, and ninth place in 1980, and Day was a 
strong contributor all three times.
Day was never the undisputed top player in Canada, but he was among 
the top ten Canadian players for over 30 years, from the late-1960s into
 the late-1990s. His peak years were in the period 1978-1982, after 
which he was eclipsed by 
Grandmasters Igor V. Ivanov and 
Kevin Spraggett. Day survived a bout with cancer in the late-1990s. He served as the non-playing captain of the Canadian team for the 2006 
Turin Olympiad. He was granted an Honorary GM title by the 
Commonwealth Chess Association in 2006.
Playing style and writings
In his youth, Day often stuck close to theoretical opening lines, but
 as his style matured, he ventured into uncharted territory more 
frequently. His style is an eclectic blend of main line theory and 
offbeat systems, which makes him very difficult to prepare for. Somewhat
 unusual for a top player, he would sometimes use the mercurial 
King's Gambit. One line he picked up from Bohatirchuk was the 
Chigorin Variation against the 
French Defence (1.e4 e6 2.Qe2), and he played this with success. During his peak years, his use of the 
Modern Defence
 placed him near the leading edge of world research there; he developed 
the Pterodactyl Variation and used it with success against strong 
players. Other favorite lines were the Closed Variation of the 
Sicilian Defence, the Grand Prix Attack against the Sicilian, and the 
Old Indian Defence.
Day was the Games Editor for Chess Canada Magazine and wrote the 
tournament book for the 1972 Closed Canadian Championship. He wrote a 
booklet on The Big Clamp opening system and co-authored a 1982 book on 
the Grand Prix Sicilian line with English Grandmaster 
Julian Hodgson. He wrote a book about the life and games of the late Canadian International Master 
Bryon Nickoloff (1956–2004), a close friend, published in 2007 by 
Chess'n Math Association.
 He is constantly updating his own selection of games, for eventual 
publication. Day became the chess columnist for the high circulation 
Toronto Star
 newspaper in 1976, and has written a popular weekly column ever since, 
now more than 1,500 in total, usually featuring some newsy information 
from around the chess world (peppered with his insightful analysis), a 
Master game with notes, and a chess problem, the answer to which is 
provided the following week. Since the late 1960s, he has been a 
successful contributor to Canadian chess magazines, respected widely for
 his great stories blended with incisive notes.
Notable chess games
- Lodewijk Prins vs Lawrence Day, Lugano Olympiad 1968, Sicilian Defence, O'Kelly / Maroczy Variation (B40), 0-1
 A highly unusual tactical game sees the young Day grab the initiative 
early on against the veteran GM, and then drive his King all the way 
down the board before castling long to force mate!
- Lawrence Day vs Duncan Suttles, Canadian Zonal Championship, Pointe Claire 1969, Modern Defence (A41), 1-0 Day and Suttles are both Modern Defence gurus, so this game is a clinic for the aspiring student.
- Kevin Spraggett vs Lawrence Day, Toronto Labour Day Open 1977, Modern / Sicilian Defence, Pterodactyl Variation (B27), 0-1 Day kept a solid edge in head-to-head games against Spraggett into the early 1980s; this one is typical of their early rivalry.
- Lawrence Day vs Ivan Morovic Fernandez, Buenos Aires Olympiad 1978, King's Gambit, Fischer Defence (C34), 1-0 Day developed many new ideas in the King's Gambit, and here he shows one of them to the Chilean GM.
- Kevin Spraggett vs Lawrence Day, Toronto Open 1980, Ruy Lopez, Closed / Smyslov Variation (C91), 0-1 In a patient strategical battle, Day fights hard to come out on top against stout resistance.
- Lawrence Day vs Pal Benko, Continental Open 1980, Sicilian Defence, Grand Prix Attack (B21), 1-0 Day co-authored a book on this line, and here he uses it beautifully to defeat a two-time World title Candidate.
- Jonathan Mestel vs Lawrence Day, Lucerne Olympiad 1982, Modern Defence, Pterodactyl Variation (B06), 0-1 Another Pterodactyl drags the English GM into a mire of dire complexities.
- Igor V. Ivanov vs Lawrence Day, Grand Manan 1984, Old Indian Defence (A55), 0-1
 Ivanov was Canada's new star after defecting from the talent-rich USSR,
 but here he finds out that Canada has some chess talent too.
- Ron Livshits vs Lawrence Day, Canadian Zonal Championship, Kingston 1992, Owen's Defence (B00), 0-1
 Day uncorks the unusual Owen's and takes on huge defensive 
responsibility. The young Livshits sacrifices several pawns, and seems 
ready to break through, but he eventually overreaches, and has to 
concede defeat.
- Lawrence Day vs Ognjen Cvitan, Moscow Olympiad 1994, Sicilian Defence, Closed Variation (B25), 1-0 Day is one of the world's great exponents of the Closed Sicilian, and here he takes off a much stronger and younger GM.
- Lawrence Day vs Dmitry Tyomkin, Ontario Open, Brantford 2004, Sicilian Defence, Closed Variation (B23), 1-0 Another clinic in the Closed Sicilian shows the young GM that Day, although getting older, still packs a pretty mean punch.
