The shuffling and carding does nothing to the placement of the selected 3 cards. It will always end up in position 6,22,38 on the 52 card stack. After removing each card to place them open and close ( odd is open and vice versa), the new positions are 8,16,24. Next iteration, the positions are 2, 6,10. Again, next iteration, 2,4,6. Last iteration, they are 1,2,3! Voila! Venture Hi · 2 years ago
