The name Emanuel Lasker will always be linked with his incredible 27 years reign on the throne of world chess. In 1894, at the age of 25, he had already won the world title from Wilhelm Steinitz and his record number of years on the throne did not end till 1921 when Lasker had to accept the superiority of Jose Raul Capablanca. But not only had the only German world champion so far seen off all challengers for many years, he had also won the greatest tournaments of his age, sometimes with an enormous lead. The fascinating question is, how did he manage that? Previously the answer frequently given was – psychology and luck. But this thesis has been refuted by authors who have to be taken seriously. Lasker’s secrets are obviously to be sought elsewhere.
