A Chess Game
A man who had never won a game of chess with his friend, one day bet him that he could simultaneously play two chess games with him, and either win one of the games or draw both of them. He made only one stipulation, which was that they alternate their moves on two separate chess boards and that on one board he got to play black while on the other board he got to play white. He said that he was so confident that he would win this bet that he would let his friend play first. His friend accepted the challenge. How was the man able to win this bet?
Answer
The friend opened with a white move on the first board. The man then made the same opening move with white on the second board. The friend made his answering black move on board two. The man then made this same answering move with black on board one. They played back and forth with the man always using his friend's moves on one board as his own moves on the other board. This meant that the friend was playing himself and that if he won one of the games he would lose the other game, or he could draw both games. But, in no way could he win both of the games!Hide Answer Show Answer
