Strategy at this node

Hit Solve to see GTO frequencies and EV.

Real version streams iterations and replaces estimate with exact Nash solution.

Range colors: fold • call/check • raise. Mixed strategies use gradients.

GTO study today is broken

• Desktop solvers are powerful but painful to use and install
• Pre-solved libraries never quite match the spot you face
• No good way to actually practice and get feedback

GTO Lab is different

The complete pro GTO toolkit in your browser: pre-solved libraries, trainers, hand analysis, node locking, preflop charts, ICM tools and more — instant estimates plus exact solving.

The complete pro toolkit

Visual Range Builder

The signature 13×13 matrix. Click, drag, filter suited. Exactly like the best desktop tools.

Instant postflop solves

Any flop, turn, river. Configure stacks, pot, and bet sizes. See strategy + EVs immediately.

Node-by-node Explorer

Walk the tree. See how frequencies and EVs change on every card. Understand why.

Training modes SOON

Drill spots. Get scored on your decisions vs GTO. Track your EV lost over time.

Instant Estimates

Fast estimates followed by precise solving. Study more spots, iterate quickly.

Features trusted by the best solvers

Massive Pre-Solved Library — Instant access to millions of solved spots for cash games, MTTs, and all stack depths. No waiting for solves.

Advanced Trainer & Drills — Practice any spot with instant GTO feedback, EV loss scoring, and targeted drills to fix leaks.

Hand History Analyzer — Upload your sessions for detailed GTO reports, EV leak detection, and progress tracking.

Node Locking & Exploits — Lock strategies and re-solve to create maximum exploitation against specific opponents.

Preflop Range Charts — Professional preflop solutions and charts for every position, format, and stack depth.

ICM & Tournament Tools — ICM-aware solving for MTTs, final tables, PKO, and bounty formats.

Plus custom bet trees, aggregated board reports, range vs range equity, tree navigation, MCP support, and everything else the top solvers (GTO Wizard, PioSolver, GTO+) deliver — available instantly in your browser.

How it works

Configure the spot

Pick positions, effective stacks, pot size, and the board. The tool auto-loads sensible starting ranges.

Build ranges & tree

Adjust the 13×13 grids for hero and villain. Choose your bet sizes and max raises.

Solve & explore

Hit solve. Watch exploitability drop. Click through every decision point and runout.

FAQ

Is this a real solver or just estimates?

The production version uses a real CFR+ engine (WASM in the browser for speed + optional server deep solves). The demo on this page uses accurate sample data to show the interface and interaction.

Will it work on mobile?

Yes. The range grid and most of the UI are fully responsive. You’ll be able to study on the go.

How accurate will the solutions be?

Target < 0.3% pot Nash distance by default (configurable). Comparable to modern desktop solvers for the tree sizes we support in v1.

When will training and preflop charts be ready?

Postflop solver first. Training, preflop library, and hand history import are the next major milestones after the core solver is solid.
