How to Use a Poker Solver: Beginner Guide
Poker solvers have revolutionized the game over the past decade. These programs use algorithms like Counterfactual Regret Minimization (CFR) to find Nash equilibrium strategies — plays that cannot be exploited. But knowing how to use a solver and how to study with one are two different skills.
How Solvers Work
A solver takes a game tree (possible actions and their consequences) and iterates through millions of simulations, adjusting strategy at every decision point to minimize regret. After enough iterations, the strategy converges toward Nash equilibrium — the point where neither player can improve by unilaterally changing their strategy.
What Solvers Teach You
Bet sizing patterns
Solvers reveal that different board textures call for different sizing strategies. On dry boards, small bets (25-33% pot) are often preferred. On wet boards, larger bets or overbets become optimal. These patterns, once learned, apply across thousands of similar spots.
Range construction
Studying solver output teaches you how to balance your ranges. For every value bet, you need an appropriate number of bluffs. For every check, you need to protect your checking range with some strong hands. This balance is what makes your strategy unexploitable.
Counter-intuitive plays
Solvers often recommend plays that feel wrong to human intuition — checking the nuts on the flop, overbetting the turn with medium-strength hands, or bluffing with specific blockers. These insights are impossible to discover through experience alone.
How to Study with a Solver
- Start with common spots — Single-raised pots in position on common board textures
- Look for patterns, not memorization — Why does the solver bet small here? What does the checking range have in common?
- Focus on your biggest leaks — Run hands where you lost the most money through the solver
- Practice implementation — Use the patterns in real sessions before studying new spots
