Expected value, usually shortened to EV, is the reason a bet can be sensible even when it loses, and reckless even when it wins. It compares the chance of an outcome with the price you are being offered.
What expected value means
A football bet has positive expected value when your estimated probability is higher than the probability implied by the odds. Decimal odds of 2.00 imply a 50% break-even point. If your honest estimate is 55%, the bet has value. If your estimate is 45%, it does not.
Confidence is not enough
Most betting mistakes begin with a confident football opinion. You might believe a team is likely to win, but the market may already agree. If the odds are too short, you are paying full price for a popular story.
- A 70% chance at 1.30 is poor value because the odds imply about 76.9%.
- A 45% chance at 2.40 is value because the odds imply about 41.7%.
- A winning bet can be bad process if the price was wrong when you placed it.
Why EV needs patience
Positive EV does not remove variance. Football has red cards, injuries, deflections, poor finishing and low-scoring randomness. A good EV process is judged over a run of comparable decisions, not one result.
How Ressq uses EV
Ressq uses EV as a filter, not a slogan. A market has to clear the probability-price comparison and pass evidence checks before it deserves attention. That is why some fixtures produce no recommendation at all.
