Return = Stake × Odds
Profit = Return - Stake
`
Example: €10 at 2.50 odds = €25 (€15 profit)

Expressed as fraction (e.g.: 3/2):
`
Profit = Stake × (Numerator/Denominator)
`
American

Bankroll Management
Fundamental rules:
- Never bet more than 5% of your bankroll on a single bet
- Define units (e.g.: 1 unit = 1% of bankroll)
- Adjust by confidence (1-5 units per bet)
- Review periodically and adjust unit size
Advanced Concepts
Value Bet
Bet with value when:
`
Real Probability > Implied Odds Probability
`
Implied Probability
`
Probability = 1 / Odds × 100
`
Example: 2.00 odds = 50% implied probability
Closing Line Value (CLV)
Comparison between your odds and closing odds. Consistently beating the closing line indicates long-term edge.
