Find the spot.
Make it familiar.

Practice, Study, My Ranges and your results work together. A spot you miss is a spot you can go back and understand.

01 / PRACTICE

Train the decisions
you actually face.

Choose the format and stack depth. Drill one to four tables, focus on close decisions, or revisit hands you got wrong.

Eight stack depths, 4bb to 50bb

02 / STUDY

A mistake is a place
to start studying.

Explore the same preflop trees you train. Follow the action by position and stack depth, then return to practice.

Feedback with a reason

See the answer.
Understand the cost.

For solver spots with EV data, feedback compares your action with the best available action. The loss is measured in big blinds. A mixed strategy can have more than one good answer.

20bb · CO · 76s · you fold
Best0.00bb lost

Solver opens 54% and folds 46%. Both are fine here, so both grade Best.

20bb · CO · JTs · you jam
Correct0.01bb lost

Solver opens 79% and jams 21%. Jamming is a real part of the mix, barely behind.

20bb · CO · AA · you jam
Blunder2.39bb lost

Solver opens 2bb with every combo. Jamming folds out everything you beat.

Know the model

Real numbers.
Clear limits.

The MBR Rush packs are HRC ChipEV solves for the 5-max Rush stage. They are not validated MBR GTO: they do not model the bounty pool or payout jumps. Final Table is unsolved.

Cash packs are Carrot Corner 6-max 100bb ranges at three stake pairs. Your imported ranges are graded against your frequencies, not presented as solver output.

Before your first hand

A few things
to know.

Have another question?
Get in touch

Is the trainer really free?
Yes. The solver spots, stack depths, multi-table practice and drills using your own ranges are available without a paid plan. Pro adds longer history, analysis and export.
Do I need an account?
You can start drilling without an account. Signing in lets you sync your practice history across browsers. Custom range sets remain in the browser where you saved them.
Where do the ranges come from?
The MBR Rush packs are HRC ChipEV solves of the 5-max Rush stage at eight stack depths. Cash packs are Carrot Corner 6-max 100bb ranges. Final Table is unsolved; imported ranges use your own frequencies.
Does it work on a phone?
This website and the demo work on a phone. The trainer is best used on a desktop or laptop, where multiple tables and the 13×13 range grid have room.
What happens to my hand histories?
Raw hand-history files are parsed in your browser. Account and practice-sync features handle other information separately. Read our privacy and data overview for the distinction.
Who operates GTO Reflex?
