Former trading floor · Risk analyst · Author
Fifteen years quoting lines, advising syndicates and sitting in casino operations taught me where the money actually goes. I wrote it down so other people would not have to learn it the expensive way: Sharp Logic on sports betting, Against the House on casino games.
The route
Six steps, in order. No dates, because the years are not the interesting part.
Early 2010s. The desk quoted lines rather than taking retail bets, so the job was pricing risk, not chasing customers. That is where you learn that the price is a product, and the margin is baked into it before anyone clicks anything.
Europe and Asia. Mostly unglamorous work: staking rules, exposure limits, record keeping, deciding when to stop. The professionals I worked with were far less exciting than the ones in the forums, and far more solvent.
Game design, RTP and volatility, then the operational side: the floor, the surveillance room, later online operations. Different building, same arithmetic. It is why the casino book is written from the same seat as the betting one.
No dramatic exit. I stopped trading, stopped playing, and found that I had a lot of explanations left over and nobody to give them to.
The betting book. How a line is built, what the margin actually costs you, why closing line value is the only honest scoreboard, and what a realistic edge looks like when it exists at all.
The casino book. The same treatment for slots, table games and live studios: how the product is designed to hold, what volatility does to a bankroll, and which decisions are still yours.
A note before you read
I worked on the operator's side long enough to know there is no villain in this story. Nobody is cheating. The product is simply built to keep a percentage, and given enough repetitions it keeps it. All of that is public, and it is written in the terms almost nobody opens.
That gap is what I want to close. People spend months arguing about systems and streaks while two numbers quietly decide most of their result: the margin they pay on every bet, and the terms of the place they pay it to. Choosing where you play is the first decision and the most expensive one, and it usually gets thirty seconds and a banner.
The books are my attempt to hand over what took me years to learn, so it costs you an afternoon instead. How a price is made. What the house keeps. Where the small amount of genuine control actually sits. There is no system in either of them, and I would not trust anyone who sold you one.
I do not play anymore. I saw it from the other side of the table for too long. That is my choice, not advice. But if you are going to play, you should know precisely what you are buying.

You are not playing against the casino. You are playing against a number the casino agreed to in advance.
The margin is not a fee for losing. It is a fee for playing, and you pay it on every ticket you ever write.
Your profit and loss tells you what happened. Closing line value tells you whether it was going to.

What I actually did
Years of risk analysis on a market-making desk, where the output is a line rather than a customer.
Independent consulting across Europe and Asia on staking discipline and risk-management process.
Game economics, RTP and volatility modelling, plus time on the floor, in surveillance and in online operations.
No current operator role, no trading, no play. Nothing on this page is a service you can hire.
