An old man who plays chess in the evenings at Starbucks asked me if I knew how many moves to count until a match is considered to be a stalemate when one player has only his king remaining?
He had been playing for many years and was now having a friendly argument about this with his opponent.
“Ten, I think” I said to him, he replied that he thought it was 25 and he turned back to his table and the game. I told him to wait, I could look it up on the internet. Being an old man he hadn’t thought of that and he liked the idea. What we discovered was that the correct and official answer is 50.
