Card magic - 2 of a Kind (for beginners)

Effect: The magician picks out two cards. He has a spectator cut the deck. He flips over the cards that he picked, then he flips over two cards of the deck that was cut. The cards match.

Secret: Before you begin the trick it would be good to shuffle the deck so the specator doesn't think you have rigged the pack in any way.
Tell them you will pick two cards. Go through the deck making sure you look at the bottom and the top cards of the deck.
Pick out a card that matches the bottom card. (If the bottom card is a Four of Hearts, you would pick out the Four of Diamonds to match it.) Then pick out a card that is the same as the top card.
Ask the spectator to cut the deck once(a simple cut).
Take the first card, the one on top of the original top of the deck, and flip it over. Flip the bottom half of the deck over completely. Flip over the cards you picked.
They all match!
