The AVRO tournament of 1938, sponsored by a Dutch radio network, was a double-round affair among eight of the strongest players in the world. The most memorable game of the event was Botvinnik's victory over Capablanca.  The “Iron Logician” systematically advances in the center, inviting his opponent to capture an irrelevant flank Pawn, and he caps his play with a brilliant ‘diverting’ sacrifice at move thirty.
