Alexander Alekhine, alcohol and a cat
Alexander Alekhine first drank heavily during the tournament at Bled in 1931, and drank heavily through the 1934 match with Bogoljubov. On October 3, 1935 the world championship match began in the Netherlands. Alekhine drank no alcohol for the first half the match, but later took a glass before most games. Alekhine abstained from alcohol altogether for five years after the 1935 match.
Hope you all right now, Alexander. In this life, we will never forget You!
