Don't quite agree, the advantage goes up slowly, and more so if you are not using a strong (and unpublished, and complicated) count. The big mathematical advantage is that both variance and covariance are lower, particularly for the S17 version. Thus you can make up for the lower advantage with bigger bets relative to your bankroll.farmdoggy said:Pros:
-Considered a carny game, most places don't even look for card counters in this game.
-Advantage increases by more per TC than in blackjack.
Hence it is easier (and prudent) to get away with a large spread.
Yes, you really want to be a simulator jockey to play SP21. But I wouldn't say a ton of indices- just like in BJ there are a dozen really good ones and the rest are of minimal value, but they can add up. One of the curious things about SP21 is that if you use a strong playing count and enough indices, the disadvantage stops increasing at extreme low counts and even turns around somewhat because you will hit more of the multi-card and 876/777 bonuses.farmdoggy said:Cons:
-Due to more complex rules, this game is harder... The basic strategy is more complex, and it is worth it to memorize a ton of indices as more of the advantage is gained by index plays than in blackjack.
-Oh, and there is alot more information readily available for blackjack... It's been around longer, studied more from various points of view.
A couple years ago, this may have been accurate, but it's certainly not the case today, now that a book has been published and there are several ridiculous claims that the game is "better" than blackjack.farmdoggy said:Pros:

True, but you can also surrender your double downs. Anyway, Kat Walker has the variance of Sp21 at 1.36 with a covariance of 0.40, while blackjack I believe has a variance of 1.32 with a covariance of 0.48, according to http://wizardofodds.com/blackjack/appendix4.htmlEmeraldCityBJ said:I also don't necesarily agree with the comments that SP21 is lower variance. Certainly the version I typically play (which allows double-double down) is higher variance. The result of several of my sessions comes down to what happened on my max bet redoubles, and I see much wilder session results and bankroll fluctuations with SP21 than I'd ever seen with BJ. I'm not as familiar with the S17 game, but recall hearing that even with it, you double-down more frequently than you do in BJ. That alone would increase your variance.
You double much less in S17 SP21, and most of the doubles you miss are the high-variance soft doubles (<A6) which I really don't miss! Hitting all those stiffs also decreases variance, because some wins and losses are converted to pushes.EmeraldCityBJ said:A couple years ago, this may have been accurate, but it's certainly not the case today, now that a book has been published and there are several ridiculous claims that the game is "better" than blackjack.
There may be a few places at remote locations who will leave you alone on Spanish, but in areas where the game is readily available, you're just as likely to get counter-measured and/or backed off SP21 as you are on BJ. More than half of my backoffs in the past couple years have been on SP21. The idea that you can blast away aggressively and get away with it is simply no longer true.

About the only benefit to learning SP21 is to give you more options. If you live in an area or travel to an area frequently which has a lot of SP21, it might be worth the effort to learn the game. If you're not able to play the game on a regular basis, I'd look for other opportunities.

I have drawn major heat [betting light green] at several casinos in A.C., but that may be primarily because I am "persona non grata" almost everywhere.
Most people receive no heat it is true and larger than normal spreads are tolerated.

how the H.E. increase if not allow to hit for splitted Aces?
That has been changed. A complaint was filed with PA Gaming, and they agreed that multiple hits must be allowed on split aces in Sp21. If you were there in the last 2 weeks and it hasn't been changed, contact gaming and remind them.geneticfreak said:Mohegan Sun Pocono also has the single card to split aces rule.
