How does clumping fair when the casino is using auto card shufflers? Good question!! In my experience shuffling machines do not eliminate clumping, nstead they help preserve it. Recognize that casinos understand that if all cards were purely random, Basic Strategy enhanced with card counting alone would beat Blackjack. If shuffle machines truly randomized cards, therefore, the casinos would not use them. Casinos are not stupid. Clumping produces a huge casino advantage. This is far more important to the casino than the convenience of shuffle machines. You can see, follow, and take advantage of clumping even with the continuous type shuffle machines.
