What is Value Betting?
Value betting is the process of placing bets when the odds offered by a bookmaker are higher than the true (or efficient market) probability of the outcome. Over time, consistently betting on positive expected value (+EV) edges can lead to profit, even though short-term variance can be high.

Core Idea
You win in the long run by consistently taking odds that imply a probability lower than the real probability. If a team has a real 55% chance to win (true odds 1.82 decimal) and a bookmaker offers 2.00, the expected value is positive.
Edge = (DecimalOdds * TrueProbability) - 1
EV% = Edge * 100Quick Examples
- True probability 60% (0.60), offered odds 1.80 (implied 55.6%) → Edge = (1.80 * 0.60) - 1 = 0.08 => +8% EV.
- True probability 45% (0.45), offered odds 2.40 (implied 41.7%) → Edge = (2.40 * 0.45) - 1 = 0.08 => +8% EV.
