Ireland's Red Black Shuffle
by Allan Ackerman

This is an overhand shuffle that allows you to retain cards in their respective half. Say you have all black cards in the top half of the deck and all red cards in the bottom half of the deck. This shuffle will keep all the red and black cards together. But it is not a complete false shuffle, because each half by itself is shuffled. This is a very useful move for effects like Out Of This World, Oil and Water, and other others.
