What Are Blackjack Side Bets?Side bets are bonus bets placed on a round of Blackjack on outcomes beyond whether the player or dealer will win. The majority are staked at the start of the round before the cards have been dealt alongside regular bets and many have fixed odds that usually offer greater payouts than the simple 2:1 rewarded for beating the dealer.Play Blackjack at Pinnacle Casino

Finding a niche market in betting can often lead to value. This can be anything from specialist knowledge of handball betting to extensive experience in betting on Japanese baseball. Providing you know more than the bookmaker, there is money to be made.  &lt;Bet on soccer at Pinnacle&gt; They also make for interesting and potentially profitable bets, as they can be a little more reliable

A corner is one of the most inexplicably exciting events in soccer. Only around three per cent of them lead to a goal, but you can guarantee that the attacking team’s fans will roar their approval and encouragement if their team are awarded one. Read on to find out how you can benefit from betting on corners.

Poisson Distribution is a mathematical concept for translating mean averages into a probability for variable outcomes across a distribution. For example, if we know Manchester City average 1.7 goals per game, so by putting the Poisson Distribution formula tells us that this average equates to Manchester City&nbsp;scoring 0 goals 18.3% of the time, 1 goal 31% of the time, 2 goals 26.4% of the time and 3 goals 15% of the time.

What is Expected Value?The amount a player can expect to win or lose if they were to place a bet on the same odds many times over, calculated through a simple equation multiplying your probability of winning with the amount you could win per bet, and subtracting the probability of losing multiplied by the amount lost per bet.A simple example of Expected Value (EV) put into practice -&nbsp;if you were

In my <a href="https://www.pinnacle.com/en/betting-articles/educational/interview-with-joe-peta-stock-trader-turned-professional-bettor">interview with Pinnacle</a>, it was clear they embraced the attitude I suggested was needed to truly expand the industry as a whole, and, as a result, attract the same type of analytics-based bettor that led to a participation explosion in poker and fantasy sports. There is no better example of this than Pinnacle’s&nbsp;<a href="https://www.pinnacle.com/en/betting-articles/educational/why-pinnacle-doesnt-close-or-limit-accounts">Winners Welcome</a> policy, as well as their cogent explanation of why a market maker in any market should embrace the presence of, what we refer to on Wall Street as, “smart money.”&nbsp;
The Winners Welcome policy is spelt out in a series of articles in Pinnacle’s <a href="https://www.pinnacle.com/en/betting-resources">Betting Resources</a> section - something that encourages customer participation in sports betting through education. Given the questions that have resurfaced both in the interview and from readers about my bet sizing strategies, this appears to be the perfect forum to formally discuss the topic further.

<h3>Wall Street trading applied to betting</h3>

Before I get into the merits of the bet sizing method I used versus the widely followed Kelly Criterion (Kelly) it’s important to recognise the importance of the cross-pollination of ideas across different industries or disciplines.&nbsp;
When I joined the accounting firm of Arthur Andersen, the consulting division illustrated the importance of evaluating best practices across industries by pointing out that Southwest Airlines improved the turnaround time of its fleet between routes not by studying other airlines but instead, the process of NASCAR pit crews.
<blockquote>In the last ten years, a period covering economic booms and historic busts, the value of an investment in the S&amp;P 500 has fluctuated 0.85% a day.</blockquote>
For my part, I bring to this discussion a Wall Street background to managing an investment portfolio, regardless of the underlying assets. First, let’s establish that while everyone wishes to make money when they place a bet, the vast majority of sports betting falls under the heading of entertainment, not investment. The rest of this piece focuses on sports betting performed by a professional as an investment vehicle, perhaps with others as passive investors, like the fund I ran for the 2012 MLB season in Las Vegas.
<h3>The importance of correlation</h3>

The aforementioned structure falls under the financial industry heading of an ‘alternative asset’. Like backing a number of aspiring golfers attempting to make the PGA Tour or a handful of poker players on the tournament circuit, these are inherently attractive investments to their backers because the returns of the investment are uncorrelated with traditional stock and bond markets. Hence the term, ‘alternative assets’.&nbsp;
The appeal of a sports investment fund is that truly uncorrelated investments are difficult to find. Investing in rare wine or comic books may seem uncorrelated to fixed income and equity markets but all it takes is a crisis in the latter for investors in the former to learn that their investments weren’t uncorrelated at all.

<h3>Evaluate your betting with the S&amp;P 500</h3>

If nearly all financial markets are correlated, what is it exactly that they are correlated to? In America, the market benchmark against which all other assets are measured is the S&amp;P 500. Representing the vast majority of the American economy, the 500 companies that comprise the S&amp;P 500 also make up an investable instrument that is the equivalent to a concept instantly familiar to analytics-based baseball bettors, the replacement player.&nbsp;
Except for investors, the concept of the replacement player is even easier to grasp than it is in baseball. Buying shares in the S&amp;P 500, through a readily-tradable ETF (Exchange Traded Fund) or mutual fund, can be achieved at virtually no cost. Just as there is a baseline performance expectation for the replacement player in baseball, so is there in the financial markets.
<blockquote>Assuming your 2% edge is exactly correct, there is a greater than 10% chance that your fund will be down at least 40% at the end of one year.</blockquote>
Investors should expect the S&amp;P 500, based on decades of performance, to return 8% a year over the long-term1. Of course, the returns won’t be smooth; market fluctuations and economic cycles introduce a high degree of variance in the short- and medium-term returns of the stock market and result in a measure of quantifiable risk.
Essentially, across the entire spectrum of financial investments, higher expected return comes with more short-term risk. Fortunately, we can measure that risk, or variance, exactly. In&nbsp;the last ten years, a period covering economic booms and historic busts, the value of an investment in the S&amp;P 500 has fluctuated 0.85% a day&nbsp;- data provided by Bloomberg from over nearly 2500 trading days from 2007-2016.
So an 8% expected annualised return has a recent historical variance of 85 basis points a day. If you can find an investment that returns 8% with less variance, or ideally, find an investment that returns more than 8% a year with the same amount of risk (as the world’s most popular benchmark for stock market investing) you’ve created a superior alternative to equity investing that you can legitimately market to others as a viable investment.

<h3>What's wrong with the Kelly Criterion?</h3>

The problem with using Kelly is that no matter what you calculate your expected return to be, your variance will be ridiculously, and to my eye, “uninvestably” high.
Take, for example, the most common illustration of the Kelly approach to bet sizing, the ability to lay even odds on a coin flip featuring a weighted coin with a 52% chance of landing on heads. Kelly suggests a bet on heads of 4% of your bankroll.&nbsp;It is empirically correct that this wager size maximises profit but it results in an unacceptable level of variance if you are endeavouring to professionally manage a sports betting fund for others.
<blockquote>Go back and look at your log of bets of a long period of time, ideally something around 250 betting days, and calculate what bet size would produce a daily variance of 85 bps.</blockquote>
The stock market is open 250 days a year and if you bet baseball on a daily basis from Opening Day through the World Series, you’ve got a season approaching that length with nearly 2,500 games to choose from. Imagine spotting a 2% game each day to invest in. After 250 days, assuming your 2% edge is exactly correct (much more realistic in say, blackjack card counting than modeling sporting event outcomes, but that’s a topic for another discussion) there is a greater than 10% chance that your fund will be down at least 40% at the end of one year. That is, to repeat what I wrote in the preceding paragraph, unacceptable as an investment vehicle.
I can’t tell you what your exact bet size should be; correct staking varies by expected edge, the variance of that edge, and the number of bets placed etc., but I can tell you how to evaluate your results from a post-mortem perspective. Go back and look at your log of bets of a long period of time, ideally something around 250 betting days, and calculate what bet size would produce a daily variance of 85 bps. If your return under that sizing strategy is greater than 8%, you may truly have created an alternative asset suitable for soliciting outside investors.&nbsp;

<h3>The Kelly Criterion and risk management</h3>

One more thought on Kelly as it relates to the business of risk management.&nbsp;A 2% edge is meaningful – entire casino empires have been built on a similar edge. For example, the standard, 38-slot roulette wheel offers the house an edge of 2.6% on a bet that pays even money. In this case, Kelly suggests the optimal bet size is not 4% but 5.2% of bankroll! The Wynn Resorts Corporation is worth more than $9b based on its stock market capitalization; MGM Resorts International is worth in excess of $16b.&nbsp;Ask yourself this: Would Steve Wynn ever let someone come into his casino, walk up to a roulette wheel, and bet $500 million on black? Could Warren Buffet place a nearly $1b roulette bet in an MGM-owned casino? No. And it’s the same reason you, if you are seriously betting on sports as an investment for yourself or others, should never rely on the Kelly formula to determine your bet sizes.
