'''Card counting''' is a [[blackjack]] [[betting strategy|strategy]] used to determine whether the player or the dealer has an advantage on the next hand. Card counters try to overcome the [[casino]] [[house edge]] by keeping a running count of high and low valued cards dealt. They generally bet more when they have an advantage and less when the dealer has an advantage. They also change playing decisions based on the composition of the deck and sometimes play in teams.
