Naps Of The Day - How To Choose Value Selections

The term NAP in betting parlance is synonymous with the phrase Best Bet Of The Day. 

online betting

The purpose of this blog is to provide some suggestions for readers on methods to identify a nap of the day or best bet of the day, irrespective of the sport in which the punter has an interest.

Most serious punters will have developed tried and trusted methodologies and systems for selecting potential investment opportunities within their preferred sports.  

We know finding winners can be very hit and miss but research is always needed. 

This research will often include an in-depth analysis of data elements, such as current form, including ratings of the individual, or team.


  •  Class, or historic form of the individual, or team
  •  Head to head results between the participants of the event
  •  The previous record of the team, or individual at the venue, or course
  •  Suitability of the venue, or course
  •  Suitability of the prevailing weather and/or ground conditions
  •  The starting position for the individual, or team
  •  Historic trends for the specific event, or type of competition
  •  Likely tactics of the individual, or team

Plus a myriad of other factors which may play a part in determining whether an individual or team are worthy of consideration for a bet that day.

Once the punter has applied their preferred methodologies to the various sporting events of the day, they are likely to have produced a shortlist of potential bets and may believe that they have finished the task and will place a bet on each selection without further analysis.

However, most shrewd punters are likely to undertake further analysis in order to ascertain the answers to the following 3 questions:

  • 1. Does each of the selections warrant an investment?
  • 2. What stake should be wagered on each selection?
  • 3. Which selection should be the NAP/Best Bet Of The Day?

The stated purpose of this blog is to provide suggestions on methods that may be used to identify the punter's NAP/Best Bet Of The Day,

In my opinion, they should be applied prior to the placement of a wager on any event, as without undertaking further analysis it will be impossible to determine which of the shortlist of selections should be elevated to the highest status. (nap)

I will discuss each of these questions in turn and provide a short case study 

I hope this will highlight the benefits of undertaking further analysis, rather than taking the view that each potential selection should be backed without further thought. 


Does Each Of The Selections Warrant An Investment?

This is often one of the most difficult questions for punters to answer subjectively.

Many will have spent significant time and effort analysing the available data to determine in their opinion the most likely outcome of a particular race, or event.

online betting

In my opinion, the term ‘value' is much overused by media pundits when discussing the chance of a competitor in a specific race. 

Every punter who wishes to make a long term profit from their wagers should always consider whether their investment offers value and if not, they should seriously consider whether it is wise to place that bet.

In many cases, the punter will have developed an emotional link with that particular outcome during the analysis process and will be keen to place a bet, as not doing so would represent a waste of the time and effort that was required to arrive at their conclusions.

However, in my opinion it would be better to keep the betting bank intact rather than place a wager on an outcome where the odds available to the punter are less than the true chance of the outcome occurring.

To put it bluntly, how many of us would be prepared to wager our hard-earned cash on the toss of a normal coin, where the odds on offer for either head or tails being the outcome were 5/6?

We know that the chance of either heads or tails prevailing is 50% either way, so why would we accept 5/6, which suggests that either outcome has a 54.5% chance of occurring?

Likewise, should not be prepared to back a particular outcome of an event at 7/4, which represents a 36.4% chance of occurring, when they believe that the true chance of being successful is 33.3%, or odds of 2/1

This is fine in theory, but the biggest problem that many punters face is how to accurately assess the true odds of a specific outcome occurring

Emotional Link

After studying the racecards have you convinced yourself that a selection will win? Have your emotions taken over?

Followers of the excellent football betting guru Kevin Pullen in the Racing Post will be aware that he is a very competent statistician, who appears to have access to an amazingly detailed database containing information relating to many different aspects of individual football matches, 

He can interrogate to ascertain the likely outcome of an event, usually from more than one angle, which he then compares against the best odds available from the bookmakers to determine whether the odds on offer are better than the chance of the event occurring.

Here is Kevin Pullen's reasoning for placing a bet on a recent Scottish Premier League match, with the headline 

“Celtic games will not always supply high scores"

"At the odds it is worth betting on a modest number of goals today when Celtic receives Kilmarnock. 

Back under 3.5 at 23-20 with Coral.

Celtic home games this season have produced some exceptional scores. 

And as you would expect, they fired in most of the goals. 

Twice the aggregate score hit six, once it reached five and twice it was as high as four. 

The average number of goals per game has been almost four.

That is unusual.

Over the previous 15 seasons, the average number of goals in Celtic's Scottish Premiership home games was just over three. 

That excludes games against Rangers, who before their financial meltdown had a budget that enabled them to compete for honours with Celtic. 

Old Firm games yielded low scores more often.

During those previous 15 seasons, 63 percent of Celtic's home games against opponents other than Rangers featured fewer than 3.5 goals.

Kilmarnock games, it must be said, have generated a slightly higher than an average number of goals for about half a dozen seasons. Even during this time, however, there have been fewer than 3.5 goals in four of their seven fixtures at Celtic Park.

Celtic are able to spend about as much on players as the other 11 Premiership clubs put together. 

Leigh Griffiths, Kris Commons (who is unwell today), Stuart Armstrong, Nir Bitton, and James Forrest have been running opposing defences ragged.

It is possible that Celtic's home games during the rest of the season will also average almost four goals. If that happens odds of 23-20 for under 3.5 goals today will not represent value for money and the bet will probably lose.

It is more likely, however, that things will settle down a bit and that between now and May there will be more low scores to add to the 2-0 defeat of Ross County and a goalless draw with Hearts. 

And that is why it is worth backing under 3.5 goals today between Celtic and Kilmarnock.”

From the level of detail supplied by Kevin Pullen, he is clearly a punter who takes time to fully analyse potential wagers and is highly unlikely to commit to a bet where the odds on offer are worse than the chance of his chosen outcome occurring.

In many respects, the outcome of the bet is immaterial in the context of this blog, as the quote has been included to highlight the need for punters to assess whether their selection is worth backing,

However, Kevin's followers would have been very content with the 0-0 draw at full time.

Clearly, any punter who has access to a similar level of data in respect of their chosen sport and uses the information wisely has a great opportunity to ensure that they are making value wagers.

Value Betting

Does your selection truly offer real betting value?

However, many punters are unable to access this level of information and therefore need to find an alternative method for assessing whether their potential selection offers value and the chance of long term profits.

There are probably plenty of possible options for assessing value, many of which I will not have encountered during my punting exploits, I have in the past used the following 3 methodologies, which I hope may be of assistance to readers.

Some of the most shrewd racing enthusiasts produce their own betting forecast for the races in which they may decide to have a financial interest.

To produce a personal betting forecast for a race, the punter will assess the chance that each competitor has of winning the event and will express this as a percentage 

so, that the sum of the chances for all runners in the race equals 100.

For example, the punter may produce a personal betting forecast for a 5 runner race as follows:

  • Horse A: 50%
  • Horse B: 33%
  • Horse C: 9%
  • Horse D: 5%
  • Horse E: 3%

Which equates approximately to the following odds for each contender

  • Horse A: Evens
  • Horse B: 2/1
  • Horse C: 10/1
  • Horse D: 20/1
  • Horse E: 33/1

To assist punters, tables are widely available which express probability in terms of betting odds.

These odds represent the minimum odds at which the punter believes that a bet on each of the contenders would break even in the long term.

However, the bookmaker will be betting to a bigger percentage to include a profit margin (known as an Overround), which in the case of this race we will assume to be 10% which means that the aggregate odds on offer will add up to 110%, as follows:

  • Horse A: 55.5% which equates to 4/5
  • Horse B: 28.5% which equates to 5/2
  • Horse C: 12.5% which equates to 7/1
  • Horse D: 8.5% which equates to 11/1
  • Horse E: 5.0% which equates to 20/1


Based on this example, the bookmaker is offering worse odds than the punter would be willing to accept on 4 of the 5 contenders.

stats

The punter would only place a wager on the race if Horse B had been the original selection, in which case he would secure odds of 5/2 in respect of a runner which was believed to be a 2/1 shot.

This is an effective method of evaluating value in a specific race and I am sure that a similar process could be developed for most other sporting events, 

In my opinion, there are a couple of fairly significant drawbacks, which require careful consideration:

Firstly, the punter must have a high degree of experience and knowledge to be able to accurately assess the chance of winning for each contestant and also be confident in their own abilities to produce an accurate betting forecast.

Secondly, it would not be too onerous to complete this task for an event with only 5 contestants, image the time that would be required to assess each contestant in the Grand National where the maximum field size is 40 runners, or produce personal betting forecasts for 5, or more events in one day.

However, there are a couple of easier options that can be used ‘off the shelf' in a similar way, which do not require anywhere near the amount of time.

The first option is to use the betting forecast that is provided by the Racing Post or another provider that produces reasonably accurate forecasts for every race.

.At a glance, most punters should be able to compare the forecast odds with the prices on offer with the bookmaker, or betting exchange 

They will be able to calculate whether they are able to place a bet at odds that represent value.

However, there are a couple of drawbacks to using such betting forecasts, in that they are produced the day prior to the race and therefore do not take into account late-breaking news such as nonrunners or going changes. 

Betting Forecasts

A good test is to regularly check how horses starting price odds differ from the overnight forecast.

The forecast may need to be recalculated but this task should not prove too onerous, especially when compared to the time and effort required to produce a personal betting forecast from scratch.

The second off the shelf option is available to punters via the various odds comparison sites that can be accessed via the Internet. 

There are numerous different methods that can be adopted when using the data available on the odds comparison sites, the simplest being to identify the median (average) odds for the selection in an event and then back it at the best odds that are available.

The main problem with this method is that whilst it ensures that the punter always obtains the best odds for their selection, which is a step in the right direction in the journey towards ensuring value betting, there is no process to determine whether that price is better than the percentage chance of the selection winning the race.

This problem can be resolved either by comparing the best odds on offer for the selection against the betting forecast published in the media, in just the same way as I detailed earlier when discussing the production of personal betting forecasts.

However, my preferred option, which works for all sports, not just horse racing, is to identify the mid-price on the odds comparison site, from which I then calculate the percentage chance of winning that those odds represent.

I then deduct a predetermined percentage from this figure depending on the sport and number of contestants due to participate in the event, which in reality represents the percentage chance of the contestant winning the event.

percents

The resultant calculated percentage can then be turned back into betting odds, which represents the minimum odds at which the punter should be prepared to place a wager

If the minimum acceptable odds cannot be bettered on the odds comparison site, then the punter should not place a bet, but if the best odds available on the site are higher than the minimum acceptable price then the punter should place the bet at the best odds that are available. 

Here is an example which may help to explain this process:

The median odds available for a contestant on the odds comparison site is 3/1.

This represents a 25% chance of the contestant winning the event. If the predetermined deduction is 20% of the original percentage chance, then 25% minus (25% x 20/100) equals 20%.

This represents the minimum acceptable odds of 4/1, so the punter should only place a bet on the selection if the best odds available are better than 4/1.

Update: I have recently developed what I believe to be a more robust methodology for assessing value horse racing selections, which can be accessed here - Introducing the VALUE CALCULATOR


What Stake Should Be Wagered On Each Selection?

I am often amazed that so many punters who clearly have a strong understanding of the sports that they regularly bet on and are capable to recording a good strike rate appear to place random stakes on their selections, 

This often results in them making an overall loss in the long run.

placw your bets

This phenomenon is often best observed in high street bookmaking shops where punters will place bets based on the amount of money that they have in their pocket at the time of placing the bet, which leads to them placing larger stakes when they are flush and lower value bets when they have less cash in their pocket.

Lack of consistency in the value of bets staked is one of the main reasons why many punters return an overall loss, although with a little self-control, they should be able to at least reduce the level of loss and perhaps even make a profit.

For the purpose of this blog, I shall presume that readers have already set aside an affordable betting bank and are aware of the need to ensure that the value of their betting bank is sufficient to cope with the inevitable losing runs, which all punters will suffer from time to time.

Many punters that have adopted a structured approach for their betting will place the same amount on each selection, which is a simple and relatively safe staking plan and is the method used by OLBG to determine the winners of their excellent monthly betting competitions.

Another simple staking plan that is often used by punters is to place a predetermined percentage of their betting bank on each selection, which means that the value of their bets will increase after they select a winner, but will decrease after a loser. Again, this is a relatively safe method, as the betting bank will never be wiped out during a significant losing run, but unfortunately lower stakes placed on subsequent winning bets make it very difficult for the punter to bring the betting bank back to the level prior to the start of the losing streak.

How Much Should You Bet?

Do you place bets based on how much money you have available in your account?

.In my opinion, there is nothing wrong with punters using either of these staking plans, but there are some interesting alternatives that the more adventurous punter may wish to consider, as in theory it makes sense to place larger bets on selections which offer the most value in terms of the odds that can be secured when compared with the chance the selection has of winning the event, as derived by the various methods in the previous section of this blog. 

One of the best options for maximising the benefit of knowing the level of value that can be attributed to a specific wager is to deploy the Kelly Criterion, which I am sure many readers will have come across in the past.

John Kelly was a telephone engineer, who wrote a paper in 1956 which suggested that someone in his position could place a delay on the telephone line that linked his local betting shop to the outside world, which would enable the engineer to know the result in advance of the betting shop.

He could place a no-lose wager on the winner. 

In this scenario, John Kelly suggests that the engineer would wager 100% of his betting bank on the winner of the event, 

There was no chance of the wager losing and then goes on to determine the percentage of the betting bank that should be wagered when the punter believes that they can secure differing advantages based on the odds available, against their estimate of the chance of their selection winning. 

The mathematics to determine the percentage of the betting bank that should be wagered can be simplified as follows:

Calculate in percentage terms the chance that the selection has of winning the event.

  • Multiply this figure by the competitor's actual odds.
  • Subtract the probability of the competitor losing.
  • Divide the result by the competitor's actual odds.

Here is a worked example based on a selection which is believed to have a 25% chance of winning an event, but can be backed at odds of 4/1:

  • Chance of winning: 25
  • Multiplied by current odds of 4/1 equals 100
  • Subtract chance of losing: 75 equals 25
  • Divided by current odds of 4/1 equals 6.25%
  • The punter should, therefore, wager 6.25% of the betting bank on this selection.


However, there are a couple of potential issues which must be considered with this method,

The resultant percentages that the punter should wager can be significantly large as in the case of a contestant with a 60% chance of winning that is available at evens requires a wager of 20% of the betting bank.

percents

The punter needs to be confident of their ability to assess the chance of their selection winning, as a relatively small error can have a profound impact on the size of the wager 

In the above example where a reduction in the selections chance of winning to 55.6% would result in the bet size reducing to 11.2% of the betting bank

One method that can be used to reduce the risk of the potential issues mentioned above would be for the punter to divide the size of the wager by say 50%, which whilst reducing the possible winnings, will also reduce the risk of wiping out the betting bank if a sustained losing run occurs.

However, my preference is to calculate the percentage of the betting bank, but then use that figure to determine the value of the bet as follows:

  • 0.0 to 4.9%: no bet (provides an additional margin in favour of the punter)
  • 5.0 to 9.9%: 1 pt
  • 10.0 to 14.9%: 2 pts
  • 15.0% or more: 3 pts

This method again reduces the potential profits from winning bets but also minimises the risk of significant losses, whilst still offering the punter the opportunity to differentiate between good, very good, and exceptional value wagers.

There are plenty of alternative staking plans that punters may consider using, 

But the most important point to remember is that if the publicised returns through using the plan appear to good to be true, then the plan probably rates as a high risk strategy, 

This may jeopardise the betting bank if a set of results go against the punter. 



Which Selection Should Be The NAP/Best Bet Of The Day?

Chance Once again, many punters select their naps based on the misguided impression that their flagship bet of the day should be the selection which has the best chance of winning and will often nap their shortest priced selection,.

They believe that they should strive for a high strike rate with their flagship bet of the day.

They will therefore nap and often place their largest bet of the day on a selection which may not warrant a bet if the odds available are shorter than the chance of the selection winning the event, or if the selection does offer value, it may not be the best value selection of the day. 

However, punters who have calculated whether their selections warrant a bet and if so the level of stakes that should be placed on each bet, should have little difficulty identifying their nap of the day, as it should be the selection that offers the best value and hence on which the biggest bet is to be placed. 

A cursory look at the Racing Post Horse Racing Naps table will invariably show that the most successful tipsters in this competition tend to have a much lower strike rate than their more prolific rivals, but by tipping value selections they record a bigger level stake profit over the duration of the competition.

A similar situation is often seen when reviewing the historic monthly OLBG Horse Racing Naps competition tables and the monthly tipster tables for other sports, where value seekers often outperform punters with high strike rates.

 Perhaps there is an element of luck involved in individual cases, but the weight of evidence suggests that over a prolonged period of time, value seekers who also employ a structured staking plan will outperform punters who concentrate on achieving a high strike rate, but take little or no account of whether their selections warrant a bet and who employ a random staking plan for their wagers. 

Hopefully, the following true story will provide further evidence.

A Short Case Study

Approximately 25 years ago, I was working in a small team with 4 colleagues on a major project, which required a level of mathematics which far exceeded our combined capabilities.

A consultant was therefore added to the team who was in my view a mathematical genius and at the end of the week on the Friday, the whole team including our new recruit went out to the local Public House for a quick drink after work, which was the regular custom for the team. 

All of the regular members of the project team were devoted sports fans who especially enjoyed betting on horse racing, so the conversation during our Friday evening drinking sessions tended to gravitate to which horses we thought would win the following day.

Horse racing

This proved to be a very enjoyable end to the working week, but we were a little concerned that our new recruit, who I must point out was a young lady, with no interest in horse racing would take to our Friday evening ritual

Indeed for the first couple of weeks she said very little during our discussions, but despite our protestations that we would be happy to chat about other subjects, 

She told us to continue to discuss horse racing, as she found the topic interesting.

On the third Friday, after a few drinks, our new colleague amazed the rest of the team when she stated that she would be able to make a bigger profit than any one of us, despite knowing little about horse racing, so we took up the challenge and each of us handed over £20 to her to provide her with an initial stake with which to bet. 

Our only stipulation being that she should explain the reasoning for her bets for the following Saturday during the Friday evening drinking sessions.

The following Friday, our new colleague joined us for a drink armed with copies of various weekly horse racing publications, plus the Evening Standard which covered the following day's racing and provided a betting forecast for each race on Saturday and information of the current odds for the main events which she had collected from local bookmakers prior to joining us in the Pub.

She then presented to us a list of horses that the tipsters had selected for the races on Saturday and explained using probability tables and the odds that were currently available, which of the tipsters selections warranted a bet and through use of the Kelly Criterion the size of bet that she would be placing on each selection.

She made a small profit on the first Saturday, but after a month the initial £100 betting bank had increased to just over £200, despite the fact that our colleague had backed only 5 winners from 35 bets placed. 

Horse racing

It was a similar story the following month and by the third month, the rest of the team had stopped backing the runners which we thought would win each race and instead were following the selections of our new recruit.

The discussions on Friday night had also subtly changed in so much as we stopped discussing which horse was the most likely winner of the race and had started to debate which of the various tipsters selections offered value at the odds on available.

We all became converts and quickly learned similar techniques to those discussed earlier in this blog and were sufficiently adept at identifying value to continue to make our betting pay.

Despite the fact that the project was completed a couple of months later and the team was split up with our new recruit leaving at the end of her temporary contract.

At her leaving party, she admitted to the team that her father owned a provincial Casino and that she had completed her thesis for her degree at university on the probability factors associated with gambling on Casino games, 

So whilst she knew nothing about horse racing, she fully understood the theory of value betting.

This was a lucky coincidence for me and my 4 fellow team members.

Summary

 Irrespective of the punter's choice of sport on which to bet, there are a number of golden rules that they need to consider prior to placing a wager on their selections, which in turn will automatically identify the Nap/Best Bet Of The Day, namely:

  • 1. Method for selection of the contestant as a likely winner?
  • 2. Does the selection warrant a bet/do the odds offer value?
  • 3. If so, what stake should be placed on the selection?
  • 4. Which selection offers the best value and should, therefore, be napped?


I am sure that plenty of punters will be deploying alternative methodologies to answer the above questions, but for those readers who wish to try out some of the ideas which have been discussed, why not apply the tests to the Horse Racing Naps that appear on the OLBG tips page, to ascertain whether the most tipped naps offer value based on the above ideas.

A similar exercise can be undertaken using one or more of the OLBG tips pages covering other sports if horse racing is not your favourite sport.

Better still, if you don't already enter the monthly OLBG Horse Racing Naps competition or the other OLBG tipping competitions, why not have a go, as they are free to enter and there are plenty of great cash prizes to be won each month. 

Finally, once you are confident that your methods are effective, apply them prior to placing your wagers with the bookmakers and on the betting exchanges. 

I hope that readers have found this blog of interest and please feel free to provide feedback (good or bad) or provide comments below if you wish to share details of the methods that you use to assess your selections, as I am sure that other readers would find them of interest.
