Two decades of IBM tournament

The Amsterdam Chess Open stands in a long tradition of strong tournaments in the Dutch capital. The period between 1961 and 1981 in particular saw two decades with wonderful, annual tournaments in Amsterdam, sponsored by IBM. As the tournament continued to grow, big names such as Boris Spassky, Anatoly Karpov and Jan Timman were among the winners. Chess journalist Peter Doggers wrote a lengthy article about the history of the IBM tournaments.
