What bettors need to know, without the fluff
Ten short guides, written from what Babeth measures every day: how to read odds, where the value is, how much to stake, and how to prove you have an edge.
Value bet: definition, formula and how to find them
A value bet pays more than the true chance of winning justifies. How to calculate it, what it really earns over time, and how Babeth finds them every day.
Implied probability: convert odds into a chance of winning
Every set of odds hides a probability. How to read decimal, fractional and American odds, why they add up to over 100%, and how to recover the true chance.
Bookmaker margin (overround): how to calculate and compare it
The margin is the invisible tax every bookmaker takes on your bets. How to calculate it from the odds, why it runs from 2% to 10%, and how to remove it.
Kelly criterion: how to calculate the optimal stake for a bet
The Kelly formula gives the stake that grows a bankroll fastest without ruining it. Formula, worked example, why to bet a fraction of it, and Babeth's 5% cap.
Closing line value (CLV): the only proof of a real edge
Beating the closing line means taking better odds than the market's final price. Why professionals judge on it, how to calculate it and how Babeth publishes it.
Surebets and arbitrage: guaranteed profit, with what limits?
A surebet covers every outcome at different bookmakers for a guaranteed profit. Formula, stake split, real risks (limits, voids, errors) and where it fits.
Bankroll management: the rules that keep a bettor in the game
How much to set aside, what to stake, what drawdown to accept. Bankroll rules explained with numbers, and what 1,000 simulations show over three months.
Parlays (accumulators): why they mostly enrich the bookmaker
A parlay multiplies the odds, but also the margins. Its true probability, what the compounded margin costs, the rare cases where it has value and how to check.
Sharp bookmakers: why Pinnacle and Betfair Exchange set the benchmark
Some bookmakers price so accurately that the market copies them. Why Pinnacle and Betfair Exchange are the benchmarks, how to use them, how Babeth blends them.
