Bogoljubow had won Bad Kissingen 1928 before Capablanca, Euwe, Rubinstein, Nimzowitsch and Reti. Alekhine accepted his challenge. A match was played in six German and Dutch cities. The winner needed 15 1/2 points and six wins. Alekhine got $6000 plus expenses. The remaining money was for Bogoljubow. Both former Russians had become 'renegates' in the eyes of the Soviets.
