Rugby Betting Theory...Value, Best Odds and Staking Strategy

What is value?

by Neville Hanbury

How can you tell if a price represents good value or not?

Well the simplest definition is that value is where you win from the bookies in the long term.

While the above is true, it doesn't tell the full story, so lets try and tackle it in more basic terms.

What does value mean in everyday terms? Well a reasonable definition might be that you achieve more worth from a purchase than it costs you. For example, you are prepared to pay £25 for a nice shirt, but you see one for £20 - that's value and you buy it. Why? Because you consider £25 a 'fair price' to pay for £25 'worth' (in your opinion) of clothing.

A similar principle applies in betting - you are buying a chance to win some money, you have a price you are prepared to pay and if you get it for less than this then you have value. The difference of course is here we are comparing payouts, so the higher the better.

Again, an example might help us to understand.

Lets say I think Bath will beat Bristol in a Guinness Premiership league game. I might decide that I am prepared to bet £2 to win £1 on this game, i.e odds of 1.50 (or 1/2 in 'traditional format'). I go to my local bookies and check the price they are offering. Lets say it is 2.00. I now have value - why? Because now I only need to stake £1 to win £1, i.e I am getting value over what I was prepared to pay. In fact anything above 1.50 would have been value.

But, lets say that instead of playing Bristol, Bath were playing Leicester, away in the Heineken Cup. For argument's sake, lets say I was prepared to bet £10 to win £1, i.e. odds of 1.1.

Now to most people (except the most die-hard of Bath fans) this would seem like over-enthusiasm to say the least, but lets persevere with the analogy nonetheless. If I was offered anything over 1.1 for Bath to win, I would take it as I have value.

Wait! I hear you holler, Bath should be about 3.00 not 1.1 for this game. Well, this is a case of beauty being in the eye of the beholder. If you think the fair price is 1.1 and you are being offered 3.00 then you should jump at it, as you have value.

Spot a contradiction?

'Value' is where you win from the bookies in the long term

Didn't I say that 'value' is where you win from the bookies in the long term? How does that equate with the 'stupid' bet above, which if it was representative of my betting would see me in the poorhouse sooner rather than later.

Well the answer lies in the fact that there are no absolutes in rugby betting, everything is based on estimation The bookies estimate the fair odds, as do you. When there is a difference you bet on where you see value.

Lets look at another example.
Lets say someone says to you that they will bet you £1 at evens (i.e. you win £1 or you lose £1 if you are right or wrong respectively) that it rains on Easter Sunday next. Would you take the bet? Well it depends where you live and what the climate is like, not to mention the long term weather forecast . On balance, in most countries, and with no further information you might decide to take this bet, figuring that the chance of rain on Easter Sunday is less than 50%, i.e you think you have value.

Now lets say he offers the same bet that there will be be no snow on Christmas day. Again, you would probably reject this, as you think there is less than 50% chance of snow.

How about if he offered you 100/1 (ie. he pays you £100 for your £1 stake if he is wrong) that there is no snow on Christmas day? Well if you lived in London (for example), then you might calculate that there is about a 1 in 20 chance of snow on Christmas day based on meteorological records. What should you do?

You should accept the bet, as you have value.

Before you go any further lets say another friend offers you a bet at a price of 1.02 that the The All Blacks will beat Romania this weekend.

Now, you may be thinking, hold on, I have just bet on something that only has a 1 in 20 chance of happening, surely if I take the 'sure thing' that is The All Blacks winning I will be better off.

Well the answer is no! What you have to ask yourself is do Romania really have as little as a 1 in 50 chance of winning (or drawing). Unless the answer is yes (and it surely won't be!) then you shouldn't take this bet as there is no value there.

Lets look at what is likely to happen. The All Blacks will probably win, and there probably won't be snow on Christmas day in London.

So, does that mean the advice above is a load of poo?

Not really (I hope)

The reason? Well lets imagine that you (and your descendants ) accepted the snow bet every year for 100 years. It is likely that it there will be a White Christmas more than once, so over the 100 years you will make a profit.

Similarly, if you bet on The All Blacks every time in matches like this, you can be sure that there will be an upset more frequently than once every 50 games and consequently you will lose money.

So that is the contradiction resolved. In rugby betting one can only ever estimate value. The proof of the pudding is that if you make a profit in the long term than you have been achieving value.

In fact we can take it further to state that it is impossible to make a profit in rugby wagering without achieving value!
So in essence value means spotting where the odds are in your favour!

There are of course many other issues involved in successful rugby betting, such as managing your money, estimating 'fair odds' etc, some of which are discussed as follows...

Shopping around for the Best Prices

by Neville Hanbury

Understanding why prices taken can make or break a bet.

In 'real life' we can often be quite lazy about shopping around for the best value, often assuming that there will be little difference in price between shops for the same item.

Sometimes this is correct and sometimes not so correct. Equally we have to consider the convenience factor. If I'm in the supermarket doing my weekly grocery shopping the extra hassle of a trip to another shop easily outweighs the benefits of the few pence I might save on a tin of baked beans for example.

The amount of time involved in checking the prices somewhere like this before deciding which bookie to use is time well spent

The same was true of 'conventional' rugby betting for example, the drudgery of traipsing round several bookies to find who had the best odds on the upcoming match mightn't be worth it to the average punter.

However with internet betting there are a host of sites, e.g. http://www.oddschecker.com/, http://www.betbrain.com/, which specialise in listing up-to-date prices from a huge selection of bookies. The amount of time involved in checking the prices somewhere like this before deciding which bookie to use is time well spent.

Let's look at two examples to illustrate the point.

1. Imagine I am betting on the Ospreys against the Cardiff Blues. Bookie A is offering a points spread of -3 @ 1.91(i.e if the Ospreys win by more than 3 points I am returned 1.91 times my stake), while bookie B is offering a spread of -4.5 at the same odds.
Now if the Ospreys win by more than 5 points then I win the same amount with either bookie, so it seems like no big deal. However consider what happens if they won by exactly 4 points. A bet with bookie A would win, while one with bookie B would lose!  The bookies may have some information that you don't have, so their spread may be more accurate.

2. I am placing two bets this weekend, both on tennis.
Match 1 sees Roddick taking on Fish (bookie A offers 1.91 on each one, while bookie B offers 2.05 on Roddick and 1.75 on Fish).

Match 2 sees Kuerten taking on Agassi (bookie A giving 2.1 and 1.7, with bookie B giving 1.91 on each).

By taking the best prices I can win money with only one of the competitors winning, while by taking only one bookies prices, I am limiting myself.

The above is especially important in matches you perceive as one-sided as there tends to be greater fluctuation in the odds. For example it is not uncommon in rugby betting to see a long shot side at 8.00 with one bookie and 12.00 with another.

The difference between a £7 profit and an £11 profit if your longshot comes in needs little more emphasis.

Bear in mind also that we are not dealing with an exact science here, we are dealing with estimation of a complex phenomena with many dependant factors.

Take the example of the rugby bet above. Lets say we had done our estimations of the likely spread and figured that the Ospreys were likely to win by 15 or more.

In such a scenario, we might think it doesn't really matter whether we get -3 or -4.5, the overwhelming likelihood is that the Ospreys will win far more easily than the indicated spread.

Stop! First of all, the bookies may have some information that you don't have, so their spread may be more accurate.

Also, even if they are wrong, there are a multitude of things that could go wrong for you. Lets say that in a freakish run of badluck the Ospreys lose their star player shortly after the start of the game, followed by his replacement 5 minutes later.

Their expected (your expectation!) dominance doesn't materialise and they scrape home by 4 points. Wouldn't you be sick if hadn't shopped around for the -3 points?

How much should I bet?

by Neville Hanbury

Like your stake medium rare or burnt to a crisp? Rugby4profit's surgery is open...

How much should you bet? How long is a piece of string?

The answer to the above question depends on four things, but the question you must ask yourself first is: do I have value?

We discussed value earlier up the page, and we will assume that you have digested and understood it.

The four things that determine your stake size are:

    1) How much money you have available to bet, i.e. your rugby betting bank.

    2) The actual odds being offered by the bookmaker or exchange

    3) Your personal preference/tolerance for safety/risk

    4) The amount of value or 'edge' you have, i.e. how wrong do you think the bookies odds are

Lets take them in turn:

1. Your rugby betting bank

1a) You should only bet with money that you can afford to lose. Seems obvious, but surprisingly easy to fall foul of. Beware of betting this month's mortgage money on a 'sure thing' etc!

1b) The next part is also fairly obvious, the more money you have available in your bank the larger your stake (bet) size can be. Because this is a personal issue (e.g. £1000 might be a huge some to one person and a minor sum to another), it is often easier to describe the bank as 100 'points' where a point can be 1p,£1, £100 etc. or as a percentage % of confidence 100% being unbeatable confidence!

1c) You need to decide whether you are going to vary your definition of a 'point' every time the bank changes (i.e. every time you make a bet), periodically (e.g. once every month or year), or systematically (e.g. every time it increases or d ecreases by £10, 20% etc).

2. The odds on offer

Many people prefer something called 'level staking' where the same amount of points are placed on every bet, regardless of the odds offered. Thus, whether I was betting on something at 1/10 or 100/1 I would use the same stake size. The big advantage is simplicity.

However we should bear in mind that on average longshots (as defined by the odds) will tend to win less often, so I am likely to lose more money betting on longshots than on short-priced favourites.

To counteract this phenomonen, many punters like to use something called 'fixed profits' staking where you stake to win a constant amount, e.g. 5 points per bet. In this scenario you would be 50 points on a 1/10 shot and 0.05 points on a 100/1 shot. If they win the returns are (One tenth of 50 points=5points, and 100 times 0.05 points=5points respectively). Fixed profits staking is generally preferable to level staking. It is slightly more tedious to calculate the stake size, but you will have less fluctations in your bank.

3. The level of risk you are comfortable with

Some people are cautious by nature, some people are risk takers by nature. Your staking should reflect what you are comfortable with. You should consider the average odds at which you bet, the number of bets you tend to have 'riding' at any given time etc when you are deciding how much to bet. Imagine you have 3 really bad days (i.e. virtual or absolute wipeouts!) in a row - which can very easily happen!

Calculate how much of your bank you would have left after this at various stake sizes and choose according to what level of risk you are comfortable with. The trade-off of course is that lowering the risk for the bad times, also lowers the size of the pay-off in the good times, but thats life! Its a very personal thing that only you can decide. However, until you are an experienced bettor it is probably better to be conservative initially.

4. The amount of value or 'edge' you have

Lets say I have 2 bets (A & B), both being offered at a price of 10.0. By my calcuations the 'fair odds' for A are 5.0 while those for B are 2.0. An extreme example it should be noted - if you get this kind of discrepancy your estimations are almost certainly wrong - the bookmakers are not THAT bad at their job! By your reckonings A has a 20% chance of winning and B has a 50% chance of winning, even though they are both offered at the same odds - 10.0.

It stands to reason that I should bet more on B than I should on A. In the case of A I have an 'edge' (offered odds/fair odds-1) of 10/5-1=2-1=1=100%, while in the case of B I have an 'edge' (offered odds/fair odds-1) of 10/2-1=5-1=4=400%.

A mathematician named Kelly worked out that the optimal stake (i.e. that which made your bank grow fastest) was sized as:

Edge/(Odds-1)

In the above example we would take 11.1% of our bank on A and 44.4% on B
