Drill the spot, not the chart

What's inside
Four tools that share one set of numbers.
Practice, Study, your own ranges and your results all read the same solver packs, so a spot you get wrong is a spot you can go and read.
Study
Walk the whole tree
Every node the trainer can deal you is browsable by position, stack and action path, with a command palette to jump straight to a spot. Final Table is marked unsolved, because it is.
My Ranges
Paste your own, then drill them
Import a range from any tool, paint it on a 13×13 grid, and the trainer will deal you your own spots and grade against your own frequencies. Saved in your browser, not on a server.
Dashboard
See what's actually improving
Hands drilled, accuracy, and a windowed view of recent performance, built from the attempt log rather than a running counter, so the number means what it says.

How it grades
One line, and the number behind it.
Answers are scored on EV regret in big blinds against the solver's best action, not on whether you matched a chart. Four grades, real thresholds, same three examples you can reproduce in the app.
20bb · CO · 76s · you fold
Best
0.00bb lost
Solver opens 54% and folds 46%. Both are fine here, so both grade Best.
20bb · CO · JTs · you jam
Correct
0.01bb lost
Solver opens 79% and jams 21%. Jamming is a real part of the mix, barely behind.
20bb · CO · AA · you jam
Blunder
2.39bb lost
Solver opens 2bb with every combo. Jamming folds out everything you beat.
What the numbers are, and what they are not
The Mystery Battle Royale packs are HRC ChipEV solves for the 5-max Rush stage. ChipEV is not validated MBR GTO: it ignores the bounty pool and the payout jumps. Final Table, where ICM and bounties change every decision, is not solved at all and is labelled that way in the app rather than filled with a guess.
Cash packs are Carrot Corner 6-max 100bb ranges at three stake pairs. Ranges you import are graded against your own frequencies and labelled as yours, never as solver output.

FAQ
Straight answers.
Is the trainer really free?
Yes. Every solver spot, every stack depth, multi-tabling and your own imported
ranges are free, with no card and no trial clock. Pro adds unlimited history,
analysis and export for people who want them.
Do I need an account?
No. Open the app and start drilling. Signing in only adds syncing your stats
and ranges between browsers.
Where do the ranges come from?
The Mystery Battle Royale packs are HRC ChipEV solves of the 5-max Rush stage
at eight stack depths. The cash packs are Carrot Corner 6-max 100bb ranges.
They are labelled ChipEV everywhere they appear, because ChipEV is not the same
thing as validated tournament GTO, and Final Table is left marked unsolved
instead of guessed.
What is Mystery Battle Royale?
GG's 18-player sit & go with a mystery bounty pool. It starts with a 10-minute
5-max Rush stage with no bounties, then the last nine players move to a 9-max
final table where eight bounties are in play. Bounties are about 46% of the prize
money, and the Rush stage is roughly 70% of the hands you play.
Does it work on a phone?
It loads, and the hand above works fine. The trainer itself is built for a
desktop browser, where four tables and a 13×13 range grid actually fit.
Do you see my hand histories?
No. Hand history files are parsed in your browser and the raw text is never sent
to any server.
The spot you just misplayed is 20 seconds away.
Open the trainer, pick a stack depth, and start putting reps on the decisions you actually face.
