This is the game of checkers (or Draughts). I am 'o' and you are 'x'.You move by typing the 'From' and 'To' coordinates and pressing the'Move' button. The bottom left corner is a0 and the top rightcorner is h7. If you want me to go first, or if you can't move,leave the 'From' and 'To' boxes empty and press 'Move'. After you havetaken one of my pieces, you will be asked to move again. If you can'tmove, leave the 'To' box empty and press 'Move'.
To keep the program to a reasonable size, it does not check for all possible illegal moves - so you can cheat!
