Can Superfun 21 be beaten with the Zen count for single decks as found on Casino Verite or even the High Opt 2 count? If you flat bet, but are using a powerful playing strategy like Zen or High Opt. can you still make money? I know Arnold Snyder recommends the Red Seven count to beat this game but I don't use Red Seven, I use Zen and can memorize the #'s for single decks easily. How much of the pack is acceptable for a dealer to cut off in single deck?
