What this GTO trainer actually teaches you
Most money lost at micro stakes is lost before the flop: limping trash, opening too wide from early position, folding the big blind to every button raise. This trainer attacks exactly that. It deals you a random hand in a random position, asks "what do you do?", and grades your answer against a baseline calibrated to published 6-max charts — instantly, with a one-paragraph explanation of why.
It's built for players moving up through NL2-NL25 who know the rules but haven't yet internalized ranges. If you still have to think about whether K9o is an open from the cutoff or whether A5s defends against a button raise, this is the fastest free way to burn those answers in.
The two drill modes
Open / defendis the starting point: a random hand in a random position, one correct action, a streak counter that resets on every miss. Learn the ranges as pure decisions first — that's what actually transfers to the table at NL2-NL25.
Mixed-frequency drill is the next layer. Pick a spot from Solver-lite and answer whether a hand always, sometimes, or nevertakes the aggressive line there; the calibrated frequency and the full mix are revealed the moment you answer. "Always" means the hand takes that action at least 95% of the time, "never" means 5% or less, and everything in between is "sometimes" — coarse on purpose, because the underlying mixes are calibrated in rough steps rather than to solver precision. The 9 free Solver-lite spots are free to drill; ELITE unlocks all 33.
How to use it
- 1.Look at the spot: your position (or the opener's position when you're in the BB) and your two cards.
- 2.Pick an action — fold, open, call, or 3-bet depending on the spot type.
- 3.Read the feedback. Wrong answers show the best play and a short explanation of the range logic behind it.
- 4.Hit "Next spot" and repeat. 20-50 spots a day is plenty.
- 5.Signed in? Mixed-frequency drill saves per-spot accuracy to your account and opens on your weakest spot next time.
How scoring works
In open/defend mode, three numbers track your progress. Streak is consecutive correct answers — it resets to zero on any miss, which punishes autopilot. Accuracy is lifetime correct answers divided by total answered; 80%+ means your preflop fundamentals are solid for micro stakes. Best runis your longest streak ever. Everything is stored in your browser, so you can close the tab and pick up where you left off. Mixed-frequency drill scores separately, per spot: a session counter plus — if you're signed in — a lifetime accuracy figure for each spot you've drilled, which is what the "weakest spots first" shortcut ranks on.
The methodology, honestly
The reference ranges are a tight-aggressive (TAG) baseline calibrated against modern 6-max 100bb opening and BB-defense charts — the same family of ranges used in our preflop charts. They agree with solver output on the large majority of hands. Where a solver would mix (open a hand 40% of the time), the trainer picks the higher-frequency action so there is always one "correct" answer. That's a deliberate simplification: at micro stakes, executing a pure baseline flawlessly is worth far more than approximating mixed frequencies badly. When you're ready for the real mixes, open Solver-lite and compare.
Frequently asked questions
Is the poker trainer really free?›
Yes — completely free, no signup, no download, no daily limit. Your streak and accuracy stats are stored in your own browser, so there's no account to create. It's one of 36 free tools on PokerPro.
What spots does it drill?›
Two modes. Open/defend drills folded-to-you opens from every position (UTG, MP, CO, BTN, SB) and big blind defense against late-position raises — the two highest-frequency decisions in 6-max. Mixed-frequency drill quizzes the Solver-lite strategies for a chosen spot: you say whether a hand always, sometimes, or never takes the aggressive line, and the calibrated frequency is revealed after you answer.
Are the answers true GTO?›
Open/defend uses a TAG-aligned baseline calibrated against modern 6-max opening and defense ranges — very close to solver output for these spots, but simplified to a single best action per hand so there's always one right answer. Mixed-frequency drill grades against Solver-lite's pre-computed, Nash-near mixes, which are calibrated to published free charts rather than solved live. Neither is live solver output, and neither covers postflop.
Which drill spots are free, and what does ELITE add?›
Open/defend mode is entirely free. Mixed-frequency drill is free on the 9 free Solver-lite spots (the five 100bb opens, BB defense vs UTG/CO/BTN, and UTG facing a 3-bet). ELITE unlocks the other 24 — SB defense, the remaining facing-3-bet and BB-defense positions, 3-bet-or-fold lines, and the 40bb/25bb open depths. Same methodology either way.
How many spots should I drill per day?›
20-50 spots takes 5-10 minutes and is enough to build the pattern memory. Consistency beats volume — a short daily session for two weeks will fix most preflop errors at micro stakes.
Where are my stats saved?›
Open/defend streak and accuracy live in your browser's local storage on this device — no account needed, but clearing browser data resets them and they don't sync between devices. If you're signed in, mixed-frequency drill also saves per-spot accuracy to your account, which is what powers the weakest-spot-first shortcut.
