Red Seven Count ( blackjack)

An unbalanced counting system devised by Arnold Snyder and included in his book, Blackbelt in Blackjack, which strikes good balance between power and ease of use. It gets it's name from the fact that the player counts only the red sevens as plus one and assigns a zero value to the black sevens. The other values assigned include plus one for 2's, 3's, 4's, 5's and 6's and minus one for ten valued cards and aces.
