What is Vig (Vigorish)?
Vig (also called juice, margin, or overround) is the bookmaker's built-in profit margin. It is why implied probabilities add up to more than 100%. Removing vig gives true fair odds, which is essential for spotting value and calculating accurate EV.

How to Use Fair Odds
- Compare offered odds vs fair odds to find value
- If offered odds are higher than fair odds, you likely have +EV
- Use sharp books (like Pinnacle) for stronger fair-odds baselines
- Lower-vig markets usually provide cleaner pricing
