Sizing Chooses Your Opponent

Because the price decides who continues, your bet does more than win or build a pot. It sculpts the range you'll face on the next street. A larger bet asks more to continue, so the marginal hands leave and the survivors are narrow and polarized — the strong and the drawing, hollowed out in the middle. A smaller bet asks little, so the middling hands tag along and the survivors stay wide and merged.

Two sizings, two different opponents

The same flop, played at two prices, hands you two different opponents on the river: one narrow and stiff, one wide and soft. You chose which before the card was dealt. So size with the next street in mind — ask what shape you want to be attacking later, and let the answer pick the number, not the local urge to "get value" or "fold them out."

Choose your bet for the river you want to play, not the pot you want to build.

Which size is exactly right in a given spot, and which hands it leaves alive, is a question of real ranges — and the principle is enough to act on without one: a price is a chisel, every bet edits his range, and by the river you are facing a shape you authored. Size like a sculptor, choosing the figure before you make the cut.

Sizing shapes which hands survive. But a big bet does something more — it loads the decision itself, and decisions made under load go wrong. That is the next movement.
