Yeah, by definition!!!
Richard,
Grand Vic Elgin offers 6D, H17, DAS with a WHOPPING 66% pen! That's a SCORE of 8.13 and N0 > 120,000 for play-all with a 1-16 spread. Backcounting brings the SCORE up to a miserable 21.91. You may not want to invest too much time looking for counters as, by definition, APs who only count are quite unlikely to play there. Also, since the house edge over a BS player is 0.63, many good players, APs or not, will avoid this game.
Many pit lurkers will read this and think of it as a positive. However, we all know that games with better rules generate more overall revenue. After all, why would the ploppies play the game if they didn't think it was beatable? You can only hold players by the ankles and shake the money loose from their pockets for so long before they stop volunteering their cash. They may play the slots in pursuit of a jackpot, but they'll have little reason to play games that offer neither a jackpot or a potential of small wins. Then what will you all do for a living?
By the way, Richard, if you want to know what we need in a game, your game with S17 has a play-all SCORE of 14.64 (yes, S17 is better for counters). Your game with LS and H17 has a SCORE of 15.40 [LS helps APs as well as casinos (it's frequently misplayed)]. As you noted, deeper pen means greater revenue for the casino while allowing more potential for APs. This is win-win as well. Many wanna-be counters will lose more betting into nothing, and ploppies will press their bets as the count drops. And deeper pen (1 deck cut off) brings the SCORE of your game up to 28.08. Not great for play-all, but something to play into (fine for backcounting). Win-win for all.
