The Best Blackjack Betting System for Finishing a Trip with a Win? Oscar's System

Blackjack Betting Systems: The Long Run Vs. The Short Run

If you are using the basic blackjack strategy, you should not be thinking of taking insurance. In the case of card counting, however, players know when it is the right moment to make an insurance bet. If you are dealt a blackjack and the face-up card of the dealer is an Ace, you will simply have to take your chances.

Players ask me more questions about betting systems for blackjack than just about any other topic. Not betting systems for card counters—just betting systems.

I always start by going into my spiel that pure betting systems don’t win in the long run. They can make you more likely to win in the short run (in the case of Oscar's System, a lot more likely). But not in the long run. And the usual response I get is, “I don’t care about the long run. I’m going to Vegas this weekend. I just want to win on this one short run.” (Continued below)

As a matter of fact, there are betting systems that provide a player a much bigger chance of finishing a trip with a win than a loss. If you use this type of betting system, and you look over your records after years of play, you’ll see a whole lot of small wins—and one (or a few) big losses, big enough to wipe out the profits from all of your small wins, and then some. (Mustn’t forget that house edge!)

But, you don’t care about the long run. You just want a win this weekend. So, let’s look at what betting system works best in the short run. We can’t guarantee a win, but there is a logic to betting systems that can greatly increase your chances of success.

Types of Blackjack Betting Systems

There are two main types of betting systems for blackjack or any casino game—positive progressions and negative progressions. With a positive progression, the general theory is that you raise your bets after wins, which means that your bigger bets are primarily funded by money won. This is a conservative betting system insofar as a long string of losses will not wipe out your bankroll as quickly as with a negative progression.

With a negative progression, you raise your bets after your losses. This is more dangerous, since a bad run of losses can wipe you out quickly. In its favor, however, it allows you to win on a session in which you’ve lost many more hands than you’ve won. Since your bets after losses are bigger bets, you don’t have to win so many of them to come back, assuming you can avoid a truly disastrous series of losses that empties your pockets.

There are dozens of variations on betting systems that incorporate features of both the positive and negative progressions, in an attempt to create the “perfect” betting system that wins the most often with the least chance of busting out.

But the best system of this type I’ve seen for accomplishing this end was first published 40 years ago by mathematician Allan N. Wilson, in his Casino Gambler’s Guide (Harper & Row, 1965). Dr. Wilson called it “Oscar’s system,” named after the dice player who’d invented it.

How to Use Oscar's Blackjack Betting System

Here’s how Oscar's System works:

The goal for any series of bets is to win just one unit, then start a new series. Each series starts with a one-unit bet. After any win, the next bet is one unit more than the previous bet. After any loss, the next bet is identical to the previous bet. That is, if you lose a two-unit bet, your next bet is a two-unit bet until you have a win, at which point you raise your bet one unit to a three-unit bet.

That is the whole system, except for one stipulation—Never place any bet that would result in a win for the series of more than one unit. In other words, if you win a 4-unit bet, and you are now down only 2 units for the series, you would not raise your next bet to 5 units because of the 4-unit win; you’d only to 3 units, which would be all you’d need—if successful—to achieve a one-unit win for the series.

Oscar’s betting system combines the best features of both the positive and negative progressions. You can suffer much longer runs of losses without busting out than you can with a negative progression, since you don’t raise your bets after losses. Yet, a much shorter run of wins can get back your previous losses on a series, since you raise your bets following wins. It’s kind of brilliant, actually. Strings of losses hurt less, yet strings of wins pay more.

When Oscar told Dr. Wilson that he had been using this system for many years and had never had a losing weekend in Las Vegas, Dr. Wilson did some mathematical and computer simulation analysis on it. Was this possible? His findings were amazing. Using a $1 betting unit on an even money payout game, the betting progression is so slow that the player would bump up against the house’s $500 maximum bet (at that time) on only one series of every 5,000 played. On 4,999 of those series, the player would expect to achieve his $1 win target.

Since Oscar was shooting for a weekend win of only $100 (back in 1965, this was a very healthy win!), Dr. Wilson concluded that it was quite likely that Oscar had played on many weekends over a period of years with never a loss.

So, should we all start using Oscar’s system? One word of caution: Watch out for that one losing series. How much does Oscar lose when his system fails on that one unlucky series out of 5,000?

About $13,000.

You see, even though he’s just bumped into the house’s table maximum of $500, he’s gotten to this point by losing lots of bets in the $100+, $200+, $300+, and $400+ range during this horrendously long series. So, if you try Oscar’s system, you still have to be prepared to lose in the long run.

Conclusion

No betting system will ever overcome the house edge in the long run. But they’re not worthless. Professional gamblers do find opportunities for profiting from various types of betting systems in gambling tournaments, as “camouflage” to disguise an advantage play that is not based on the betting system itself, and especially in online casinos where betting systems can be used to milk the casino “bonuses.”

To actually win at normal casino blackjack in the long run, however, you have to start by counting cards--not because card counting is the best or most profitable way to win at blackjack, but because the principles behind card counting are the same principles that are behind every type of professional gambling at blackjack, even methods that don't require counting.

By Henry Tamburin
One of the most often asked questions from players about blackjack strategy, is 'how should I bet?' You've got several options and I'll discuss them in this article and offer my recommendation.

Flat Bet Blackjack Strategy

This means betting the same amount all the time. Most players don't like to bet this way because they figure if the dealer wins more hands then them they'll never win any money. Also players feel it's boring betting this way. They prefer the thrill of sometimes betting more in the hopes that when they do so, they will win the hand and make a nice profit.

Here are the facts on the flat betting blackjack strategy. If you bet say $5 on every hand in a standard multiple deck game the house will have an edge of 0.5% against the skilled basic strategy player. That means you will lose on average 0.5% of every wager you make. So if you bet $10 on every hand and average 80 hands per hour you will have made a total of $800 worth of bets. The casino expects to earn 0.5% of the $800 or $4.00. Of course the more likely result is that you'll win or lose much more than $4 after an hour of play. But on average you can expect over time to lose at the rate of $4 per hour.

Let's take an example of a player flat betting $10 on every hand. It's is a conservative betting strategy that leads to a relatively low theoretical loss rate. The fluctuation in this player's bankroll will also be low which means the likelihood he'll have a big winning or losing session is not great.

Progressive Betting Blackjack Strategy

This is where things get interesting. The Progressive betting blackjack strategy is when players vary their bets in some way from one hand to the next rather than always betting the same amount on every hand. There are all different types of betting progressions but they all have one common denominator. You either decrease or increase your next bet depending upon whether the hand you just played won or lose.

Win progressions encourage you to increase your bet size after a winning hand. For example you make a minimum bet of $10 and if you win, you raise your next stakes on next hand to $20.

There are all different kinds of win progressions. The most common is a 1-2-3-5 progression. This means you increase your bet by the above multiples after each winning hand but as soon as you experience a loss, you start the progression over with a 1 unit bet.

Proponents of win progressions will tell you that you'll win more money if you win 5 consecutive hands compared to the amount you lose if you lose 5 consecutive hands. Of course what they don't tell you is that you never know when that 5 consecutive winning hand streak will occur.

There are also betting progressions in which you increase your bet following a loss. These Martingale type betting progression are dangerous and you should never consider using them.

There is also hybrid betting progressions, which have you increase your bets following a win, but after two or three success wins you lock up some profit and gradually regress your bets. The creativity of progressive bettors is never ending.

First of all, blackjack strategy for betting progressions do not change the 0.5% house edge one iota. There has never been a correlation between the hand just won (or lost) and you chance of winning the next hand. In other words using the criteria of the result of one hand (W/L) to base how you bet on the next hand has no scientific validity. So betting progressions in the long run don't work in the sense that they won't improve your long-term chances of winning.

But here's what betting progressions will do. First off they increase the fluctuation in your session bankroll compared to flat betting. This means you can win more using a betting progression compared to flat betting but you can also lose more. Secondly, betting progressions will increase the amount of money you wager per hour compared to flat betting. If a $10 bettor uses a 1-2-3-5 betting progression, his average bet will $20. Over an hour he will average $20 times 80 hands or $1600 worth of bets. The casinos expected win is 0.5% of $1600 or $8. In other words a $10 progressive bettor stands to lose twice as much per hour as a $10 flat bettor.

Here's a tip to save you some money in the long run if you insist on using a betting progression. Instead of starting your progression at $10, start at a lower amount (ie. $5). This will reduce your average bet to $10 per hour and cut you hourly theoretical loss rate in half.

But in the long run flat betting and betting progressions don't work in the sense they won't change the house edge against you and you will lose in the long run. So what betting system works? That my friends is card counting.

Blackjack Betting Strategies And Tips

Betting When You Have The Edge (Card Counting)

With card counting you know when you have the edge based on the change in the composition of the decks and therefore you'll know when it's the right time to bet more. So unlike betting progressions that are based on whether you win or lose the previous hands, card counting is based on the mix of cards that were played on previous hands. If more small value cards were played in previous rounds, there are more big value cards left in the unplayed cards and the edge shifts from dealer to player. This would be the best time to bet more.

But I'm realist. Not a whole lot of average blackjack players have the time or mental concentration during play that is required to master one of the popular point count card counting systems. These are readily available in blackjack books. But even though millions of blackjack books have been sold since Ed Thorp's classic book, Beat The Dealer (circa 1962) first revealed card counting to the masses, the number of players who can successful win money in the long run at blackjack number in the hundreds and thousands.

So what's the answer to betting at blackjack for the average player? I asked Don Pronovost that same question about four years ago. Don is a software developer that markets blackjack training software. He spent the better part of two years and a trillion computer simulated hands looking for the solution to this dilemma. What he developed is Speed Count.

Blackjack Betting Strategies That Work

Speed Count is unlike any conventional card counting system. It's much simpler to master and requires much less concentration when you play. And unlike progressive betting systems, Speed Count will give you a verifiable advantage over the casino You can read about Speed Count in Frank Scoblete’s book, Golden Touch Blackjack Revolution.

Now that you know the scoop on betting at blackjack, I wish you many aces and faces the next time you play.
