About this course
Red 7 is Arnold Snyder's answer to the same problem KO solves, removing the true-count conversion. Its landmark is zero. Count red sevens as +1 and black sevens as 0 (half the sevens, an average of +½ per seven), start at −2 per deck, and when your count crosses zero you have the edge. Raise bets at zero, play stronger at +2. No division anywhere.
This course stands alone. If you are choosing your first system, compare it with KO on the comparison page, since they fill the same role. Bankroll, game selection, and cover are in the Card Counting course.
