The smartest bet is always zero.
The second smartest, you can check.
Fair prices, above-fair flags, arbitrage alerts, and Kelly sizing. Every number worked out in front of you, step by step, on one board.

§1 · the lesson plan
What the board does
A board that shows its work
Every book's price, side by side. Best price underlined in teal chalk. Above-fair prices boxed in yellow. Stale lines flagged in pink, with the time the book last moved. Nothing here is more certain than its timestamp, so the timestamp is always shown.
Fair value, derived
Odds include the book's cut. Teacher's Bet strips it out (three de-vig methods in Quant mode, plain English in Simple mode) and measures every price against the sharpest line in the market. When a book pays above fair, you see how much, and why.
Sizing you can interrogate
Kelly-formula stake sizing, and you can replay every step. Your numbers go into the derivation and the answer gets circled in chalk. When your inputs contain no edge, it says $0, the honest answer.

Teacher's Bet is an analytics tool for informational and entertainment purposes only. It does not accept wagers, hold funds, facilitate bet placement, or give betting advice. All outputs are calculations on user-supplied inputs. No feature of any tier guarantees any outcome.

Fair questions
Do you sell picks?
No. Teacher's Bet never says "bet this." Every output is arithmetic on inputs you supply or on posted odds, with the full derivation shown. If our math says a price pays above fair value, we show you the benchmark, the method, and the timestamps. You decide what that's worth.
Can Teacher's Bet guarantee profit?
No, and be suspicious of anything that says it can. Even arbitrage, the closest thing to a sure thing on paper, carries real execution risk, and the tool says so every time it flags one. Fair math beats confident promises.
Where do the odds come from?
Commercial odds feeds, with every quote stamped with when it was pulled and when the book last moved it. Until live feeds ship, the board runs on clearly-labeled demo data.
Why should I trust the math?
You don't have to. You can check it. Every result has a "Show the work" button, the methods are documented in plain language on the Learn page, and the math library itself is public source code.
