This game was played during the Canada Day Open in 1999, held at Dalhousie University in Halifax, Nova Scotia. The tournament is a traditional celebration of Canada’s national holiday, bringing together a mix of local masters and dedicated club players in a competitive open format.
Harold Uuetoa, a seasoned player in the Canadian chess circuit, is known for his presence in Atlantic Canadian tournaments.
Alvah Mayo is a respected figure in the Nova Scotia chess community. Mayo is known for his resilient and tactical style, often finding creative solutions in unbalanced positions.
The match took place on July 1, 1999, the opening round of the tournament. In the first round of an open, higher-rated players typically face tricky opponents who are looking to cause an early upset. There was an air of festive energy due to the holiday, but on the boards, the tension was high. Mayo chose the Queen’s Pawn Game (Modern Defense style), a choice that frequently leads to sharp, non-traditional struggles.
The game is an explosive encounter featuring an early Queen sacrifice and a prolonged struggle where Black’s minor pieces eventually overwhelmed White’s heavy material.
The Tactical Explosion The game deviated from theory early when White played 4.Be3, allowing Black to strike at the center with 4…Qb6. The tension peaked at move 6: White played 6.Nd5, threatening the Queen, and Black responded with the shocking 6…dxe3!, giving up the Queen for a Knight and a devastating initiative.
After 7.Nxb6 exf2+ 8.Kxf2 axb6, the board was completely transformed. Black had only two minor pieces for the Queen, but White’s King was exposed on f2, and Black’s pieces were perfectly coordinated.
Mayo demonstrated great patience, using his Knights and Bishops to harass White’s position. By move 19, White’s Queen was forced into awkward squares. Black utilized the open a-file and b-file with his Rooks to create constant threats. The engine notes that while the material favor sat with the Queen, the practical difficulty for White was immense.
The game swung decisively in Black’s favor when White allowed the infiltration of the Black Rooks. After 33…c3, the pressure on White’s queenside became unbearable. Mayo liquidated into an endgame where his Bishop pair and Knight completely dominated White’s Queen.
The final sequence was clinical. Mayo used a series of checks with his Bishop on e5 and g1 to paralyze the White King. By move 48, with his pieces perfectly centralized and White’s position collapsing, Uuetoa resigned.
