\"OverFootball managers often have half-baked ideas on their tactics or new players to sign, but they never instruct their team to score half-a-goal because, well, that\u2019s an impossibility.<\/p>\n

That\u2019s one of the reasons why punters get so confused about the .5 goals lines that the bookmakers offer. You can\u2019t score half a goal, that\u2019s a given.<\/p>\n

But when you understand the logic of the 0.5, 1.5, 2.5 and so on goal line, and what the numbers mean, it becomes so easy to follow and unearths a potentially profitable betting market for savvy punters.<\/p>\n

It’s the sort of thing you only need to learn once, and it’s so simple that you can never forget how it works, so this article will hopefully unlock a new betting market for anyone who has never used it before.<\/p>\n

How Does the .5 Goals Market Work?<\/h2>\n

\"Football<\/p>\n

The bookies use .5 goals as it makes it easier for punters to understand the over and under lines.<\/p>\n

So, let\u2019s look at an example. Liverpool are playing Manchester City at Anfield, and the bookmakers are offering odds of 8\/11 on Over 2.5 Goals. What does this mean?<\/p>\n

Let\u2019s break it down. If three or more goals are scored, then the game has gone \u2018over\u2019 the 2.5 line. If there are two goals or fewer, it has stayed \u2018under\u2019 the line.<\/p>\n

The game can’t end with 2.5 goals scored, so the bet will definitely win or lose.<\/p>\n

The same logic applies to all of the other \u2018half goals\u2019 that the bookmakers price up.<\/p>\n

So, over 1.5 goals pays out when there are two or more goals in a game \u2013 in this case, the unders line wins if the game finishes 1-0 to either team or 0-0.<\/p>\n

For the over 3.5 goals line, we\u2019re looking for games with stacks of goals \u2013 four or more, to be precise. That includes final scores like 2-2, 3-1, 2-3 and so on. For under 3.5 goals, you\u2019ve guessed it, three or less goals is the order of the day. Here, we\u2019ll be cheering on scorelines like 0-0, 1-0, 1-1, 2-0, 1-2 and even 3-0 to either side. All would see the unders line pay out.<\/p>\n

Using Goals Data In Our Betting<\/h2>\n

\"Over<\/p>\n

The chances are that, if you follow a particular league or competition closely, you will already have some idea of how each team plays \u2013 whether they attack and get plenty of bodies forward, or if they are conservative and defend deep with players behind the ball.<\/p>\n

Clearly, the strategy of each team determines whether they are good candidates for the overs or unders side of the .5 line. From a betting perspective, it\u2019s worth taking a look at the data, so here\u2019s how the Premier League 2021\/22 season looked after 22 rounds of matches:<\/p>\n

Even at first glance, we can get a good idea of how each team goes about their business, plus the likelihood of the overs\/unders lines paying out for any given fixture.<\/p>\n

Using a very crude formula, we can calculate how likely a game is to go over or under a specified line. Let\u2019s say Manchester United are playing Southampton. We use the data to note that United go over the 2.5 goals mark in 48% of their games, whereas for the Saints it\u2019s 55%. If we average out the two, we could say there\u2019s a 51.5% of this game finishing with three or more goals scored. However, in this imaginary scenario let’s imagine that both teams have key defensive players out injured, so we will adjust it to 52%.<\/p>\n

As we know, percentages can be used as a way of calculating implied probability, which we can then convert to fair odds that the bookies might offer (forgetting, of course, the over round they build in to their prices).<\/p>\n

So, in this game:<\/p>\n

    \n
  • Implied probability of Over 2.5 Goals = 52%<\/li>\n
  • Fair odds = 1.92 (around 9\/10)<\/li>\n<\/ul>\n

    Now, we head to our preferred betting site\/app, and look up the Over 2.5 Goals odds. We find that this is priced at 1.73 (or 8\/11), and so on this occasion we aren\u2019t getting value, because our calculated probability is lower than that being offered by the bookies.<\/p>\n

    So, is there value in the Under 2.5 Goals market? Let\u2019s run the numbers again. This time we are saying that there\u2019s a 48% of there being two or fewer goals \u2013 the opposite of the equation given that we think there\u2019s a 52% of the \u2018overs\u2019 landing.<\/p>\n

      \n
    • Implied probability of Under 2.5 Goals = 48%<\/li>\n
    • Fair odds = 2.08 (around 11\/10)<\/li>\n
    • Bookie odds = 2.10 (or 11\/10)<\/li>\n<\/ul>\n

      And so we have calculated that the under 2.5 goals line is the value play here, as the bookies are offering us better odds \u2013 albeit marginally \u2013 than we have calculated as fair.<\/p>\n

      Of course, this is a system that requires far more inputs \u2013 team news, form of the two sides, home advantage, weather, upcoming fixtures etc \u2013 for it to be considered an accurate strategic approach. But hopefully you can see how the data can shape your over\/under .5 goals bets.<\/p>\n

      Over\/Under 2.5 Goals vs Correct Score<\/h2>\n

      \"UnhappyIf we have a particularly strong feeling about the number of goals that are going to be scored in a game, is it more profitable to back the correct score market instead?<\/p>\n

      The answer, invariably, is no.<\/p>\n

      Let\u2019s take 0.5 goals first. If you back under 0.5, you are basically backing 0-0 \u2013 the odds are the same. If you back 0.5 goals, you would need to Dutch around a dozen scorelines to cover most, but not all, of the potential scorelines.<\/p>\n

      The 1.5 goals line becomes interesting when you are expecting a low scoring affair, and so would normally back the unders. Let\u2019s run the numbers of under 1.5 goals and the three correct score bets that could make this happen \u2013 0-0, 1-0 and 0-1 \u2013 from that Man Utd vs Southampton game:<\/p>\n

        \n
      • \u00a310 on Under 1.5 Goals = \u00a333 profit<\/li>\n
      • \u00a33.11 on 0-0, \u00a34.76 on 1-0 and \u00a32.13 on 0-1 = \u00a330.45 profit on any<\/li>\n<\/ul>\n

        When we try to cover every possibility, we can see that the odds are skewed to make the correct score bets unprofitable.<\/p>\n

        The only way we can make the system work is if we miss out some of the possibilities. Let\u2019s take a look at a potentially one-sided contest: Man City vs Brentford. Here, the over 2.5 goals line is priced at 4\/9, but sensing a heavy Man City victory we can play just a few of the available correct score options:<\/p>\n

          \n
        • \u00a310 on Over 2.5 Goals = \u00a34.44 profit<\/li>\n
        • \u00a34.42 on 3-0, \u00a32.21 on 3-1 and \u00a33.38 on 4-0 = \u00a318.70 profit on any<\/li>\n<\/ul>\n

          So we can see how backing selected correct scores can be a more profitable avenue than the overs line \u2013 around 400% more, in this example. But our risk is that we only have three scorelines covered, and although we could hedge in play by backing more, we soon start to erode our profit margin.<\/p>\n","protected":false},"excerpt":{"rendered":"
