This is probably the oldest form of cartomancy, dating back to the 16th century at least. People would cut the deck to pull one card, essentially to test whether their luck was running high, before making a decision. Similar principles led to the development of solitaire games in the 17th century.
Shuffle the deck. Cut it and reveal the card at the bottom of the upper stack.
