ChessBase Christmas Puzzle Contest

Puzzle 1 – Dec. 27


Proof game 4: Position after White’s 7th move

In this example it is important to remember that the position must arise after White's seventh move (there are a number of solutions after Black's seventh). [December 27]

Puzzle 2 – Dec. 30

Recently a friend told me the following story about the death of his grandfather: "My grandparents used to go to church on Sundays. One day during the sermon, which was long and dry, my grandfather fell asleep. That week he had been reading a novel about the French Revolution and began to dream that he was a rich aristocrat living in a beautiful chateau in France. Suddenly there was a commotion outside. A mob of peasants appeared, stormed the house, grabbed him and tied him up, dragged him to the market square, where there was a platform with a guillotine set up. My grandfather was led up the stairs, a priest muttered a few words to him and then his head was placed in the cradle of the guillotine. A hooded executioner approached and reached up for the lever that releases the blade. At that moment my grandfather was snoring quite loudly, so my grandmother reached out and pinched him on the back of his neck to wake him up. This was such a shock to my grandfather that he suffered a heart attack and died on the spot."

My reaction to the story of my friend: "I don't believe a word of that. You made it up." Why did I react in this way, how did I know the story is not true. [December 30]

The solution is not, as some have suggested, that one cannot dream while one is snoring (people can). It is also not the fact that the executioner reached up for the lever, which is much too high for him to reach. Inaccuracies in a dream do not constitute a logical fallacy that invalidate the story – – if the grandfather had been reading Star Wars he could have easily dreamt that he was about to be decapitated with a laser sword. There is a more basic and elementary reason why we know that the friend's story is not true
