Geometric bet sizing
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.
Frequently asked questions
What is geometric bet sizing?
Betting the same proportion of the pot on each remaining street so that the stack is exactly committed by the river. Because the pot grows with each bet, the chip amounts increase while the fraction stays the same.
Why is it efficient?
Because it extracts the maximum over multiple streets. Spreading the commitment evenly means each bet is as large as it can be while still getting called — one enormous bet folds the range out, three measured bets take the whole stack.
When should you use it?
With a strong, polarised range and more than one street to play — typically from the turn with a nutted hand against a range that has to keep defending. It is a planning tool: you choose the river's size on the turn, not when you get there.
