How does a poker solver select bet size? Doesn't this depend on posteriors on the opponent's 'policy' + hand estimation?

How does a poker solver select bet size? Doesn't this depend on posteriors on the opponent's 'policy' + hand estimation?
- boscillator 9mo agoNo, I'm not super certain, but I believe most solvers are trained to be game theory optimal (GTO), which means they assume every other player is also playing GTO. This means there is no strategy which beats them in the long run, but they may not be playing the absolute best strategy.
- sejje 9mo agoTypically when you run a simulation on a hand, you give it some bet size options. To limit the scope of what it has to simulate. It's unlikely they're perfect, but there's very small differences in EV betting 100% vs 101.6% or whatever.
- meep_morp 9mo agoNot only to limit the scope of what it has to simulate, but only a certain number of bet sizes is practical for a human to implement in their strategy.
- Reason077 9mo agoGTO (“game theory optimal”) poker solvers are based around a decision tree with pre-set bet sizes (eg: check, bet small, bet large, all in), which are adjusted/optimized for stack depth and position. This simplifies the problem space: including arbitrary bet sizes would make the tree vastly larger and increase computational cost exponentially.
