What a tiny lovely thing! I catched a glimpse of it in Cologne, while we were waiting for the tramway. a black-and-white Mini car, whose name is "Check Mate"
I saw this in Chessbase. A stamp from the Central African Republic which celebrates one of the greatest world champions: Mikhail Botvinnik. The most interesting thing is that it includes the diagram of the critical position in the game Botvinnik - Capablanca, in the AVRO tournament played in Brussels in 1938. Kasparov wrote that this game represents the transition from the era of talented players to the era of study and preparation. I guess most of chess players have played the game through and know which the next White move is.
