Fundamentals of Sports Betting (Betting on Over/Under ‘X’ Goals) is unlike any other book you will find elsewhere. It contains insights into how mathematics and statistics are applied to bookmaking, information that is rarely (if at all) found in the public domain.
Have you ever wondered how bookmakers set their odds? They must be pretty good at it to remain trading in a high risk industry built on small margins!

It is common knowledge that the gambling industry as a whole relies to a large extent on the ignorance of its customers and, only by understanding how bookmakers think and act, will you ever be able to compete with them on a level playing field.
The Most Valuable Book About Betting You Will Ever Buy!
This course is designed to give you the essential, fundamental knowledge necessary to understand odds calculation and the bookmaker market.
It deals with relatively simple descriptive statistics and teaches you how to look at data sets, calculate your own probabilities and odds, analyse the market odds on offer, and make informed decisions when predicting football results.
Amongst the topics you will work through are distributions, deviations, graphs and charts, odds calculation, financial terminologies, risk management, and of course, how to identify ‘value’ in the betting market.
You will gain a deep understanding of the many different elements required to understand the bookmaker market and odds calculation. Many false beliefs that the majority of gamblers and fans of football have about betting will be exposed and stripped away.
Readers will also be enlightened to learn about how odds are set in the market, where to find ‘errors’ in market prices, how to evaluate data and graphs, and much, much more.
What Do You Get For The Money?
The course comes in electronic format and the bundle includes the course book (PDF*) and a Bundesliga cluster table (Excel) for studying. This course employs a didactic method of teaching, which is an educational technique. It is a very structured style of learning and as such, each section of the course should be mastered before moving on to the next.
To further encourage you to learn, there is a plethora of exercises to practice what you have learned, and the solutions to the exercises are found at the end of the book, sometimes embellished with further explanations.
All of the course lessons are presented in a pragmatic, easy-to-follow, step-by-step fashion, with no more than passing respect towards the sport of football and the passion of its fans. After all, this book has been written by a lady who loves maths but dislikes football…!
In addition, you will receive the very latest Bundesliga table for the current season, so that you can put into practice what you have learned and within the course, you will find a discount code enabling you to download for free the German Bundesliga sheet in future seasons, meaning that you will always have access to the most current Bundesliga cluster table, forever: it doesn’t matter when you bought the course.
*By the way, the PDF is a professionally formatted document and if you have a double-sided printer you can print your own book for studying.

I got a little confused with %cv adjustments
Say I got a range of fair odds 1.25 to 1.35 for over 1.5 market
What odds is considered value back bet?
What odds is considered value lay bet?
Is it the same for over and under market ?
Thanks
Hi Teck Chuan,
You only bought the course 2 days ago. It takes a genius to work through and completely understand the whole book in such a short period of time.
Therefore, please work through the course from the beginning, do all the exercises, especially everything in part one, before you even look at part two (which is about betting though; I therefore understand that you probably read this part first and are now stuck) and then you will be able to answer your own question with great confidence.
Good luck!
It’s a lot to learn, I appreciate this. But learning and comprehending takes time!
I found the first course an invaluable insight into how the markets are priced and how things work, and will certainly be looking to add this updated edition to my collection.
Everything I have purchased so far from Soccerwidow has been excellent and very good value and I would have no hesitation recommending the products to friends and family.
Many thanks!
Hello Soccerwidow,
Came across your site. Found out you got a new course to offer.
I am really interested and wondering if you do also bet based on what you teach in the course? Can I find any P/L records on your site?
Thanks,
Paul
Hi Paul,
You will find an answer to your question in the article Frequently Asked Questions – Fundamentals of Sports Betting Course. Please scroll down to the bottom, you’ll find an answer to your question there.
You may also be interested in the other ‘ethical’ questions asked by readers.
I’m looking forward to your custom,
Soccerwidow
I have just done over 100 matches of quartile betting, total goal market with %CV adjustments.
Unfortunately I have not successfully gain a positive yield. At the moment about -3% yield, 20 units fixed risk/gain staking plan.
Would you mind to help me out?
1. I took historical odds statistics/results from Betexplorer. Their match result 1×2 odds is average bookmaker odds prior to match start.
2. The leagues that I’m currently betting are MLS, Brazil, Japan, Sweden, China and Denmark.
Majority is MLS Brazil and Japan. Have I selected wrong leagues? So far hits and misses for all leagues except for Brazil.
3. I bet when 10% value, 70% hit rates appear. I have seen many instances where a back bet shows 1 – 5 % value, but lay bets shows a much higher value, 20 to 30%. Is it true that lay bets usually holds more value than back bets?
4. MLS brazil and japan has 85 matches of data, Sweden china and denmark has only 75, is 75 matches data enough? I wonder this affects my odd computations.
5. My spreadsheets will evenly divide data into 4 quartiles. Unlike what you have shown in your PDF where you divide them manually. Some 22 some 19. Do you think its ok?
6. I would like you to have a look at my spreadsheets and my betting records, if thats OK.
Please advise. I really hope to bet for long term.
Hi Teck Chuan,
Some leagues play statistically more reliable than others. Brazil definitely yes, Japan and China, no. It probably depends on their league format. But I cannot say that for sure.
To you request to have a look at your spreadsheets… This is something I must unfortunately refuse. We have so much work that we don’t know what to do first; I cannot add anything more. Sorry! However, ask your questions here, and I’ll reply as much in detail as possible.
Best wishes,
Elena
Hey there why is japan not a good choice?
I compare leagues with 5 years average relative deviation. is that good enough?
focusing on any market which has 3.5% and below deviation.
Hi TeckChuan,
Japan may be a good choice or not. Truly, I don’t know. Each league follows different patterns. What applies to one league does not necessarily applies to another.
We mainly concentrate on the EPL and Bundesliga, and what I can say for sure is, that Japan has different patterns to those two leagues. But is is impossible to know every league in and out. For everybody, also for us. Therefore, as you are probably more interested for the Asian leagues that for the Europeans, then there is no reason why not to specialise on them. Just be careful to ‘mix and match’ in an intelligent manner, not randomly. Stick to a few leagues, learn everything about them, and become a master.
Best wishes,
Soccerwidow
Results
Excluding Sweden, Denmark and China leagues,
41 matches of Major league soccer, yielded about 9%
12 matches into Brazil league, yielded 29%
13 matches into Japan league, yielded 2.4%
MLS, Brazil and Japan has about 85 matches for quartile analysis.
I would say this looks pretty promising. Thank you soccerwidow
Well done!
Keep reporting 🙂
Hi,
I’d like to know whether we can use the same stats and math to find value about 1X2?
This course is the first of a series of books educating the ‘Fundamentals of Sports Betting’.
There are more topics planned such as ‘Betting on Home, Draw, Away’, ‘Asian Handicap’, or ‘Betting In-Play’, and so on. Of course, it will take a while until all of these books have been written and published, but we reassure you that more course books are on their way.
For the first volume we have chosen the Over/Under goal market because this is the easiest betting market to teach statistics and maths without the need to dive any further into much more advanced formulas and concepts. You will need a basic grounding before moving on to more complex calculations for bet types with multiple options such as 1×2, HT/FT and the Correct Score market.
To answer your question… yes and no… The 1×2 market uses more or less the same stats and maths, but to reliable find value there is more to consider than explained in this Over/Under Goals course.
I do not understand this part. please help.
I bet when 10% value, 70% hit rates appear. I have seen many instances (betfair exchange) where a back bet shows 1 – 5 % value, but lay bets shows a much higher value, 20 to 30%. Is it true that lay bets usually holds more value than back bets?
Hi TC,
you cannot generalise that lay bets hold more value than back bets. It all really depends on the market price offered for the bet.
Please continue working through the course, repeat the exercises, until you really understand everything.
Just as an aside, I asked a trained actuary to read through the course and provide me with comments as we are currently looking for a publishing house. Here is one of her comments:
Probably four different times, I tried to jump ahead and not do some portion of the earlier exercises, because I was convinced I knew the probability calculations already. And even though I do, I found I really needed to just work through everything methodically if I really wanted to understand it. I bet other readers probably try to do the same thing! However, going through everything slowly and steadily, it is very well laid out and each piece builds on the next, just as it is intended to.
Therefore, please, work and work and work through this course, and continue working. You may even have to repeat the exercises several times in order to understand everything. Please really work from the beginning to the end, don’t skip a single chapter.
Good luck!
Hello,
May I know prerequirement to read this e-book?
In order to keep this book down to a reasonable number of pages I have assumed that readers have had a little experience with statistics in the past. For example, you are familiar with terms such as ‘mean’ or ‘median’, can handle some graphs, and you may vaguely remember having seen a ‘distribution’.
I have also anticipated that readers have a basic knowledge of mathematical operations and recognise signs used in algebra such as ‘x’, ‘y’, the summation sign, etc. Furthermore, I have assumed that the reader understands fundamentals such as finding the square root of a number, or squaring a number (or at least know where to find the right buttons to press on your calculator), and so on.
But please don’t worry if you are challenged by maths or regard yourself as extremely rusty; I do explain things as thoroughly as possible as we go along.
Of course, you’ll need a computer to read this PDF document, and having a calculation program such as Excel will certainly also help working through the exercises.
Hi there,
On Page 67 there’s a link: ‘Soccerwidow Value & Probability Calculator’, however it isn’t clickable on OSX. Could you tell me where it leads? 🙂
Thanks!
Hi Stan,
here’s the link: True Odds & Value Detector: League Games with H2H History
Perfect, thanks! 🙂
Another question: on page 69 you mention ‘Consistency with statistics is of vital importance’ with regards to using an unbroken chain of 25 matches, however, does this same principle apply to the H2H matches? Or can these be from any year as long as there are 6 or more in total?
Of course, it would be better if you could get 6 consecutive matches, or even 10, but teams have the habit of dropping out of a league and coming back again. Therefore, just 6 (or more) from the last 10 years is enough. There isn’t a way round it.
Thanks! And just to make sure – if a team has dropped out of a league 1 season due to degradation and got back in the next, would this render all future statistical analysis useless due to the break? Following the ‘consistency’ mantra seems to suggest so…?
Or, can I interpret the ‘consistency’ better by reading it as ‘never skip any available data’?
….ow, rereading that I meant the 25 streak, not the H2H games since you answered that 🙂
