Problematics | I hold the four aces

Over a year and a half, we have solved enough puzzles together to agree that tough does not necessarily mean best. He now calls upon the fourth victim: “Pick up Pile D and deal the top three cards face down on the table.” Victim #4 does as instructed. “Deal the next card on top of Pile A, the next on top of Pile B, and the next on top of Pile C. When that is done, place the remainder of Pile D on top of the three cards you dealt on the table.” Once these instructions are followed, the smart alec returns to Victim #3. Then place the remainder of Pile C on top of the three cards you dealt on the table.” The pattern is becoming familiar now. The trickster instructs Victim #2 to deal three cards from Pile B face down on the table, then one card each on top of Piles C, D and A, and finally place the remainder on top of the three cards dealt on the table.
