Imagine that you have a 9 by 9 chessboard and an unlimited collection of dominoes. The upper left corner, lower right corner, and the square in the very middle of the chessboard are all cut out with an exacto knife. Is it possible to tile the remaining part of the board with dominos? Remember that each domino must cover exactly two squares of the chessboard either vertically or horizontally.
Think you have the answer? Then send me an email at sbr@wfu.edu.
Good Luck!
