My Friend has 3 cards face down on a desk. One is a queen and other two are kings. He knows which card has queen and king. You can ask my friend one YES or NO question, but when you do, you need to point to one of the cards. If you point to an king, he will tell the truth, if you point to the queen, he will randomly say YES or NO. You have to find one of the kings.

Tell me what question you need to ask my friend?
