From a standard pack of cards, I remove four cards, one of each suit, and one of each of he ranks Jack, Queen, King and Ace. I lay them out in a line face downwards. Now, you have been given the following facts:

(a) The Heart isn’t next to the Club.

(b) No card is next to its immediate senior in rank.

(c) The colors of the suits alternate.

(d) The king and Queen are facing opposite directions.

Identify the four cards and their correct order.

Generally speaking a problem should have a unique solution unless it is other wise posted in the problem.  The correct cards is unique but their order is not.  Especially the statement and "their correct order", which suggests one solution.  I disagree with the posted solution as well.  At least looking at Microsucks Freecell deck in windows XP.  The KC and the QH face the same direction.  I enjoyed working the puzzle but was disappointed in the two or four possible solutions.
