The Language of Bet Sizing
What "Wrong Size, Real Cost" teaches
What specifically breaks, and by how much, when a sizing choice is wrong.
It sits inside The Language of Bet Sizing: A bet-size is never chosen per-hand — it is one entry from a small menu a strategy commits to in advance. Learn what a size actually buys (pot odds, Alpha, MDF, value:bluff ratio, as one connected cascade), why a strategy abandons a size the instant it can be raised rather than using it less, why that abandonment costs surprisingly little EV on average, and why relative polarization — not hand strength — sets both the direction and size of every bet.
What you'll learn
- Size vs frequency fix
- Reverse linear mechanism
