MIKO (also known as the Three and a Half of Clubs trick) is a comedy prediction card effect where the magician declares he has a card in his pocket that is half the value of the spectator's card. When the "Seven of Clubs" is announce the magician feigns disappointment before turning over a specially printed Three and a Half of Clubs card.

It was marketed in 1943 by Harold Sterling. He named the trick to honor Milt Kort who had recently left to join the United States Army.
