I am at a loss for good blog fodder today, so how about an amusing chess-themed puzzle I recently came across? It’s a simple question: What is it that the queen cannot do that a king, rook, bishop, knight or pawn can all do? Good luck!
Come to think of it, here’s another puzzle I’ve always liked. Nothing to do with chess this time. Imagine that you are in a pitch black room. No light at all. You are seated at a table. On the table is a standard deck of fifty-two cards, stacked neatly and squared away. Forty-two of the cards are face-down, while ten are face-up. Of course, since the room is completely dark you cannot see how the face-up cards are distributed within the pack. For all you know it could be the top ten cards that are face-up, with all the others face-down. Or maybe it’s the last ten cards that are face-up. Or the face-up cards might be distributed in some haphazard way. Your task is to divide the cards into two piles in such a way that the number of face-up cards in each pile is exactly the same.
Again, good luck!
