Shuffle the TRACS cards and ask a spectator to hold the deck face down in his hand. Say, “Without looking, please remove any two cards from the deck and put them in your pocket so neither of us can see them. In TRACS, a pair of cards is called a "trick". So you now have the first trick in your pocket.”

Tell the spectator to take the next two cards off the top of the deck, to turn them over and to place the trick (face up) on the table. Say, “In TRACS, a match (Red-Red or Blue-Blue) is called save and a mismatch (Red-Blue) is called a strike. Here we have a save [or strike, whichever is the case].” Turn your back and have the spectator repeat with subsequent pairs from the deck, keeping saves and strikes in separate stacks on the table. When all cards have been paired, remind the spectator that TRACS is The Game of Confidence and Consequence, and ask: “What do you think is the consequence (strike or save) of the first trick (in your pocket)? What is you confidence?”

“Well”, you say, “Let’s ask the cards. What’s your favorite color, Red or Blue?” [Assume Red]. Pick up the stack of strikes and take out all the Red cards. Lay the cards down on the table, one at a time, chanting “strike, save, strike, …”. If the chant ends on strike [save], say, “So the first trick must be a strike [save].” Ask the spectator to take the first trick from his pocket and lay it on the table face up. He will find that that the consequence (strike or save) matches your prediction.

The trick is most effective when it is done for a crowd where each member of the audience has their own deck of cards  - since you will correctly predict the "first trick" (save or strike) for every one of them.
