Card Steering – Card steering is an advanced technique where the player cuts the decks in such a way so as to allow for specific cards to appear during the first rounds after the reshuffle. This is usually done with favourable cards like aces. The player would wager larger amounts of money at the start of the next shoe since they know when the favourable card is to be dealt.

Card Steering is not a new blackjack technique but it does require skill. What happens is a team of players take over the entire blackjack table.
