Riddle solved: Capablanca missed several drawing opportunities

About a week ago Karsten Müller invited readers of his latest endgame riddle to take a close look at the 34th game of the World Championship match between Alexander Alekhine and José Raúl Capablanca in Buenos Aires 1927. It was the last and the decisive game of the match – Alekhine won in an instructive rook ending. Zoran Petronijevic and Wolfram Schön had a very close look at this historically important game and present interesting discoveries. | Photo: Capablanca (right) and Alekhine at the World Championship 1927, the man in the middle is the arbiter Carlos Augusto Querencio | Source: Wikipedia
