Geometric bet sizing
Also: geometric growth of pot, GGOP
Sizing bets across the remaining streets so that each bet is the same fraction of the pot and the last one is exactly all-in. It is the sizing that puts the maximum pressure on a bluff-catcher with the fewest bluffs, and it is what solvers converge to in many polarised spots.
Example. With 3x pot behind on the turn, the solver bets 75% twice rather than 33% then all-in.
If you have two streets left and the effective stack is 2.6 times the pot, a geometric line is roughly 80% pot on the turn and 80% pot on the river, which lands all-in. The idea is that the opponent must call a fixed fraction at every step, so their overall defence frequency is lowest when the fractions are equal. Deviating — small then huge — lets them fold cheaply or call cheaply.
