Daniel Yanofsky was Canada’s first grandmaster. In 1939, just 14 years old, he played for Canada at the Buenos Aires Olympiad. Yanofsky was the sensation of the tournament, making the highest score on second board. In this game he unleashes a pretty rook sacrifice to win a game which was highly praised by World Champion Alexander Alekhine
