After identifying a card counter, the casino has several options. In terms of altering the game procedures, the house can take action in several ways (all detrimental to the card counter).

Probably foremost, the house can shuffle earlier in the pack. As the penetration is decreased. the card counter faces a progressively steep uphill climb. Recall that deep penetration into the pack is desirable for card counters.

Another countermeasure is to restrict a player to flat betting. Clearly, a betting ,spread of sonic sort is required for a card counter to be successful, and if a casino imposes flat betting, this is bad news for your card-counting career at this establishment.

A casino can also introduce more decks into the game. Remember, fewer decks are preferable for players.

The house may resort to preferential shuffling, which means the dealer shuffles at will. In its worst form, a floor man or dealer counts down the deck and preferentially shuffles the pack when the count becomes favorable to the player. III our opinion, this is unethical, as it changes the expectation for the game even for players who are not counting, and hence, are oblivious to what is happening to them.
