That is the title of this ten-page paper by Dr Tom Murphy VII (!), a computer scientist whose homepage is http://tom7.org/. The abstract of Dr Murphy’s beautiful paper consists of one word, and the paper is dated 1 April 2019, but it’s no April Fools’ prank, or is it? Below is the paper’s esoteric research question:
“… what if you are forced to be one of the chess pieces [in a life-or-death chess match]? That is, your little soul inhabits one of the 32 pieces or pawns and your soul is vanquished if that piece is eliminated. Now it doesn’t matter whether you’re good or bad at chess,because you don’t get to pick what happens in the game. What matters is that your piece lives to the end of the game, when all surviving pieces are set free. Which piece should you want to be?”
Hmmm … Where have we seen this before? Maybe here.
