Flat Betting
Definition
Flat betting means wagering the same fixed amount on every bet regardless of perceived edge or confidence. It is the simplest staking strategy and is popular because it limits downside risk and removes emotional decision-making from bet sizing.
Example
You decide every bet is exactly 1 unit ($50). Whether you see 2% edge or 8% edge, the stake stays the same. This reduces variance but may sacrifice some long-term growth compared to Kelly-based approaches.

Kelly Criterion
StakingThe Kelly Criterion is a mathematical formula that determines the optimal fraction of your bankroll to wager on a bet with positive expected value. It maximizes long-term growth rate while minimizing the risk of ruin. Many bettors use fractional Kelly (e.g., half or quarter Kelly) to reduce variance.
Bankroll Management
StakingBankroll management is the practice of setting aside a dedicated sum of money for betting and following strict rules on how much to wager per bet. Proper bankroll management protects you from going broke during inevitable losing streaks and ensures long-term survival.
Unit Size
StakingA unit is a standardized bet size expressed as a percentage or fixed amount of your bankroll. Using units allows bettors to compare performance regardless of bankroll size and helps maintain discipline in staking.
Staking Plan
StakingA staking plan is a systematic approach to determining bet size. Popular plans include flat staking (same amount every bet), proportional staking (percentage of current bankroll), and Kelly staking (optimal fraction based on edge). The choice of plan affects both expected growth and variance.
