Learn Texas Hold'em and GTO strategy
Free guides to GTO poker strategy: ranges, equity, pot odds, bluffing frequencies and how to train with the simulator.
These guides teach the ideas the trainer grades you on. They are written for players who already know the rules and want to stop guessing: what equilibrium frequencies are, how to work out a call with pot odds and equity, how much of your range has to defend against a bet, and how to turn a graded hand into a specific thing to practise next.
They are short on purpose. Each one covers a single idea end to end, with the arithmetic shown so you can check it yourself at the table.
A suggested order if you are starting from zero:
- What GTO actually means — the idea everything else rests on, and what it does not promise.
- How to use this trainer — the three modes, what each panel answers, and a first-week routine.
- Preflop fundamentals — position, opening ranges and the first re-raise.
- Pot odds, equity and EV — the arithmetic behind every call.
- Bluffing frequencies and MDF — why bet sizing decides how often you may bluff.
If you would rather just play, open the trainer — every decision you make there comes back with the equilibrium frequencies, the EV and a grade, and the guides are here for the moments when a number does not make sense yet.
A note on how to read them: none of these pages ask you to memorise a chart. Charts are snapshots of one set of conditions — stack depth, position, who is still to act — and they stop being true the moment those change. What is written here instead is the reasoning, with the arithmetic shown, so that you can rebuild the answer at a table you have never seen before. Where the theory genuinely has more than one defensible answer, the page says so rather than inventing a number.
If you only have ten minutes, read the pot-odds page. It is the one piece of arithmetic that comes up in every session you will ever play, and it is the difference between calling because the price is right and calling because you want to.
- What GTO actually means (and what it does not promise)Game Theory Optimal explained without jargon: why equilibrium is a mix of actions, why it cannot be exploited, and where it stops helping.
- How to use this trainer (and what each panel is telling you)The three modes, what equilibrium frequency, EV, MDF and SPR each answer, and a concrete first-week routine that turns grades into practice.
- Preflop fundamentals: position, opening ranges and the first re-raiseWhy position is worth money, how opening ranges widen toward the button, what a 3-bet is for, and the five preflop leaks that cost most players the most.
- Pot odds, equity and EV: the arithmetic behind every callHow to work out what a call needs to win, the rule of 2 and 4 with its limits, and the EV formula that settles the decision.
- Bluffing frequencies and MDF: why bet sizing decides everythingHow often you may bluff at each bet size, how much of your range has to defend, and where minimum defence frequency stops applying.
