Doug, So it isn't the case (no pun intended)  without the extra characters (cards) you can't win, like in poker, and so you fold.

If you think of a piece of paper with the uppercase alphabet written at the top of the page, and the lowercase alphabet at the bottom, and then folding the page in half so that the uppercase letters are on top of the lowercase letters (or vice versa), that's kind of the image.
