(We will never really know how good Vera was. She was killed in a bombing raid in 1944, at the age of 38. However, she was clearly the best woman player of her time, better than most men and the equal of some of the great male players. Vera played and beat Max Euwe, Samuel Reshevsky, C.H. Alexander, Frederick Yates, Edgar Colle, Karel Opocensky, Sir George Thomas and Sultan Kahn. In 1929, She was invited to the Carlsbad International Tournament which included such players as Jose Capablanca, Savielly Tartakover, Aron Nimzowitsch and Max Euwe.)
