A short course on betting with an edge — the math, the market, and the tools, in order. Start at the top and read straight through, jump to what you need, or ask a question in the chat on the right.
Foundations
What is a +EV bet, really?6 minPlain-English EV: the formula, the math, and why the bet you lost might still have been the right one.How vig works (and why books make money even when they're wrong)6 minSportsbooks don't need to predict outcomes. They just need to charge a margin and balance their book. That margin is the vig, and it's why most bettors slowly lose.Variance vs edge: why a +EV bet can lose, and a -EV bet can win7 minEdge is what you earn per bet on average. Variance is the noise that hides it. You need both, and you need to size for the variance, not the edge.No-vig fair odds: the number behind the number6 minWhen EV Blacksite says 'fair line is -108', that number is the market's true probability with the vig stripped out. Here's how it's calculated and why it matters.Closing Expected Value (CEV): the only post-hoc scorecard worth checking7 minWin or lose, a bet's quality is decided by how the market closed, not by the score. CEV is how EV Blacksite grades whether your bet actually beat the market.
Market structure
Moneyline vs spread vs total: what each is actually asking7 minThe three columns on every game ask three different questions: who wins, by how much, and how many points get scored.Why two books never agree on a line, and why that's the whole game6 minThere is no central truth in sports odds: every book runs its own model and takes its own money, and the gaps between them are where +EV lives.American, decimal, fractional odds, and cents formats5 minFour ways to write the same price: how to read each format, convert between them, and why there's no such thing as -50.Half-points and how a 0.5 shift moves price6 minMoving a spread from -2.5 to -3.5 looks tiny. You're buying the probability of one exact score margin, and nobody knows that number for sure.Totals: why O/U scoring is more predictable than people think5 minEvery sport's combined scoring clusters around a few numbers, which makes totals the most learnable market in betting, but not a safe one.
Reading books
How to read a bet slip across 7 books5 minEvery bet slip is the same six fields in a different costume. Here's what to verify, in what order, before you confirm.Sportsbook account hygiene: getting limited and what to do about it7 minWhy books limit winners, which habits flag you fastest, and why getting cut at one book is normal, not game over.
EV intuition
Why +EV bets cluster on underdogs (plus odds)6 minPublic money piles onto favorites, books reprice to survive, and the leftover value lands on plus odds. Here's the mechanism.Why not every +EV bet is profitable5 min+EV at log time is a snapshot, not a verdict. Here's what variance, line movement, and a systematically wrong market do to it.Liquidity, line movement, and why timing matters5 minSignals decay because other people see them too: how lines firm up toward game time, and what to do when your number moves first.Dead zones and gap edges: probability mismatches books don't price6 minBooks price each spread leg independently, and nobody prices the narrow margin where both legs die. That gap is a bettable mismatch.
Prediction markets
Kalshi 101: what it is and how it differs from a sportsbook6 minKalshi is a federally regulated prediction market, not a sportsbook. Different fees, different liquidity, and no one gets limited.Polymarket 101: crypto-native prediction markets5 minPolymarket is Kalshi's idea on a blockchain: USDC funding, on-chain settlement, and payouts that quietly differ from the advertised odds.
Using EV Blacksite
What's a "strategy" on EV Blacksite?5 minSystem, user, and custom strategies: what each one is, how signals flow through them, and why committing to a rule beats picking bets ad-hoc.Auto-resizing: what it is and when to turn it on5 minThe nightly job that regrades every strategy and adjusts your stake: the metrics it reads, the tiers it assigns, and when to lock it out.Sizing ladders: Kelly without the headache4 minWhy stake recommendations come in clean round numbers instead of exact Kelly decimals, and why that's a feature, not a compromise.The strategy simulator: what it does and when to use it4 minBacktest a filter set against historical signals, see which segments actually made money, and why the results can flip when you change one slider.Recalibrator: what changes when a line moves5 minThe line you can actually get isn't the line in the signal. The Recalibrator prices the difference, game by game, not from a static table.Paired bets: arbs, middles, and the dead zone7 minTwo coordinated legs at two books: guaranteed arbs (Double Agent), overlapping middles (Pincer), and the inverted gap (Dead Zone) nobody else prices.The API and MCP: your bankroll's research, in your own tools6 minTwo transports onto the same data (a REST API and an MCP server) so you can pull EV Blacksite's signals into your own scripts, notebooks, and AI assistant.The free preview: real signals, a few a day4 minWhat you get before adding a card: a curated, ~10-minute-delayed sample of the real product, with the full math shown, three fresh snapshots a day on one shared timer.Building your own betting agent7 minHow to build an agent that pulls EV Blacksite signals and works a book for you, the deterministic playbook that keeps it honest, and the pitfalls that quietly turn a good bet into a bad one. Do this at your own risk.
Skill-building
The craft of staying solvent5 minThe discipline pyramid, why the bet you skip pays like the bet you make, and the review loop that keeps you solvent. Access to signals is not the hard part.Reading your own bet tracker: what to look at, what to ignore5 minROI is the loudest number and the noisiest. CEV is the most honest. How to read the four headline metrics without fooling yourself.
