Quite small, but larger than a nano (barely)

I have other similar hides around but this one is a little higher up the difficulty scale (hint, hint).

In cards, you really gotta know the right time to bluff.  A good bluffer can use this to his advantage.  I am not sure if there is such a thing as a double bluff, but when there are two folks bluffing and one guy holding great cards, there sure can be some good rewards for one of the players.  I will leave it to you to decide which one should win this one.

When you get to this site, stop and look around.  The double bluff should be apparent.
