# Can you figure out how this card trick works?

I gave this problem to ChatGPT but it did not figure out how it works.

I ask you to choose a card from the deck without looking at it and say that it will be the ace of spaces. After you choose a card, I look at it and say that it is the ace of spades. I then tell you to choose a second card without looking at it, and say that it will be the 10 of diamonds. I look at the card and say that this is correct. I then say that I will choose the 7 of clubs. After I choose a card, I turn over all 3 cards and they are indeed what I said they were.

There’s any number of ways you could do it. First, you never didn’t have control of the deck AND you were choosing the cards, so you could have simply pre-arranged them.

Second, you had control of the cards AFTER they were drawn as well, which means you could have simply switched them afterwards.

Third, the deck could be in random order and you changed nothing, but had some kind of marking or indicator on the back of the card that told you what it would be before you drew.

Marked deck

Come on guys! If I do the trick a second time, I will again start with the ace of spades, but the other two cards will probably be different. Hint: I get to see two of the cards and get to choose the third one.

The trick is done with an ordinary deck of cards. A marked deck would do no good, because I say what card will be chosen before you choose it.

Okay, here is how it works. You are going to be embarrassed by how easy it is. It does not require a marked deck or much skill.

I know beforehand where the ace of spades is. I keep a hand on it and make it unavailable for selection. Let’s denote the first card chosen (which will definitely not be the ace of spades) as card 1. I then announce that the next card you choose will be card 1, when in fact it is some other card, card 2. I then say that the card that I choose is card 2, when it is in fact the hidden ace of spades. The three cards selected match the 3 cards that I announced – ace of spades, card1 and card 2. The order in which they are chosen is different from the order I announced, which I cover up by giving the 3 cards a shuffle before turning them over.

I don’t think I would have figured that out. Maybe if I saw the procedure or visualized it more and had more brains. I once did a card trick when I slowly shuffled a deck of cards and ask the participant to stop me at any point and that the top card would be the Ace of spades. When I stopped and handed them the deck without looking and proceeded to walk away leaving the person totally befuddled. But I still can’t figure out how it works. I promise I didn’t make 52 attempts. Just 2 ;P

It is a simple trick I used to do to astound my nephews.
