Question:
Is it possible for several variables to come together to make an otherwise unfavorable situation successful, even if just for a short time?
Even for a short period of time? You can double your 16's vs dealer ace and it might work for a short time. You will often see people you might consider horrible blackjack players win for a short time. Then again it is perspective, is a day, week, month, year etc etc a short or long time?
I've been testing this with friends around a 6-deck shoe... a lot. More often than not, it works. And with double-downs and splitting pairs, the final payback is even better than it would be with straight doubling the bet on a loss.
When you double you should always have an advantage on that hand, so doubling having a better payoff is not surprising. The same is true on most splits and even on those splits where you do not have an advantage the purpose of splitting is losing less, so again a better payoff. What you discovered is just playing martingale and ignoring advantageous situations is foolish.
I'm exploring a few of the variables; some I can't test until the next trip to the casino.
For example, I'm looking for the right amount of people at the table. So far, heads-up with the dealer seems like a 50-50 proposition, whereas having a small number of additional players... say, 2 to 3... spreads out the losses.
How many people on the table:
If you do not count you will lose long term, so the more people on the table, the less hands you play, so the less you lose.
If you count and the count is positive, the less people the better because you will get more hands in a positive situation.
If the count is negative you want to play less hands. So you want more players or you just leave the table.
How many decks is optimum? I've been practicing with 6-decks, but would 8 or 2 be more advantageous? I need to explore this more.
The fewer decks the less the disadvantage to the player, if the rules are the same. But take into consideration which game you will be playing most often and work on that. There are a few good single deck games and many good double deck and six deck, but there are tons more bad ones, so learn to recognize the good from the bad.
What's the best seat? So far, this is working well (in practice) no matter which chair I choose, and I've moved all over just because friends have complained that I always get the best cards. Still, they're aware of what I'm trying to do and helping me with these rehearsals.
If you know which seat will get the ace on the first card that is the seat you want. Otherwise there are seats better for hole card play and good seats for signaling a partner. There really is no best seat.
Might this work better or worse with an auto-shuffler? I don't like the idea of being dealt back the same cards that have just been picked up from the table, but I need to at least test it if I want an answer.
Blackjack is math. Short term, luck has its place but winning long term is nothing but math. You can not use math against an auto shuffler.
How much cash should I start with? Obviously, the more you can risk the better you can stay with any system, but with less, I've been able to turn around a bad streak by having an earlier cut-off point. Starting with $2,000, betting $10, I might start over after losing 5-6 hands, with $1000, I may want to give up after losing four hands. If things go well, I might make up my $80 loss in just eight more hands, and make it back to where I left off. I've had things go bad on me (in practice) too -- like splitting three cards, and doubling-down on one, then losing, and then, the next very hand the dealer gets Blackjack. It happens, but not a lot.
If you were a friend or relative, based upon your not counting and this post my very strong reccommendation would be for you to start with 0. It will save you money.
Still, I'm learning a counting system... I just need something to do until I'm comfortable enough to start employing it.
