What Tools Do Poker Pros Actually Use to Study?
Ask a winning player how they got good and the answer is almost never “natural talent.” It’s hours away from the table, with software. The catch is that no single program does everything, pros run a small stack of tools, each solving a different problem. Understanding what each piece does, and in what order to use them, is the difference between busy study and study that actually moves your win rate.
The three jobs study software has to do
Think of off-table work as three separate jobs, not one. First, you need to learn what the theoretically correct play looks like. Second, you need to drill that play until it becomes reflex. Third, you need to find out which of your own habits are quietly costing you money. Most players stall because they obsess over the first job and ignore the other two, they can recite theory but freeze when the same spot shows up live.
A useful way to map the toolkit:
| Job | Tool type | What it answers |
|---|---|---|
| Theory | Solver | ”What’s the optimal play here?” |
| Reps | GTO trainer | ”Can I find it under pressure?” |
| Leaks | Tracker / HUD | ”Where am I actually losing money?” |
The order matters. Theory without reps stays academic, reps without a leak-finder waste time drilling spots you already play fine, and a tracker full of leaks is useless if you have no way to learn the correct fix. The three jobs feed each other, which is why pros treat them as a system rather than a shopping list.
Solvers: the theory layer
A solver calculates a game-theory-optimal (GTO) baseline for a given spot, how often to bet, which hands to bluff, what sizing to use. Tools in this category, like PioSolver or GTO Wizard, are the reference library that modern strategy is built on. If you want a fuller breakdown of the concept itself, our explainer on what GTO poker is walks through how these baselines are calculated and why they matter.
Solvers are powerful but slow to learn from. They hand you a grid of percentages, not a decision you can make in three seconds. Studying solver output teaches you why a play is right; it does not, on its own, teach your brain to reach for that play at the table. That gap is where a lot of study time leaks away.
There is also a practical difference between the two main flavors of solver. A standalone engine like PioSolver runs computations on your own machine, which gives you full control over inputs but demands a real understanding of how to set up a tree. A browser-based library like GTO Wizard precomputes common spots so you can look them up instantly, which lowers the barrier but locks you into preset assumptions. Beginners almost always start with the precomputed approach, because the goal early on is to absorb patterns, not to run custom simulations.
Trainers: turning theory into reps
This is the layer most casual players skip, and it’s where real table skill is built. A GTO trainer feeds you hands one after another, asks for a decision, and scores it against the solver baseline, so you’re not just reading the answer, you’re producing it, repeatedly, until it’s automatic.
DEEPFOLD sits here. Instead of staring at a static range chart, you play through spots and get immediate feedback on how close your choices track optimal play, which builds the pattern recognition that survives contact with a real game. It’s most useful once you already understand the fundamentals a solver teaches, it’s a reps machine, not a substitute for learning the concepts in the first place. Used that way, DEEPFOLD is the bridge between knowing the right answer and finding it instinctively.
A concrete example shows why reps matter. Suppose a solver tells you that on an ace-high flop the in-position player should continuation-bet a small size with close to a hundred percent of their range. That is easy to read and easy to nod along to. Now picture the same spot at the table: you hold a weak suited connector, you missed the flop, and instinct screams “check, you have nothing.” A trainer forces you through that exact decision dozens of times until betting your whole range stops feeling wrong. Reading the chart took thirty seconds, but rewiring the instinct took a hundred repetitions. That is the work the middle layer does.

Trackers: finding your leaks
The third tool works on hands you’ve already played. Trackers like PokerTracker or Hold’em Manager import your hand histories and turn them into statistics, your aggression by position, how often you fold to a three-bet, your win rate from the blinds. A heads-up display (HUD) can overlay similar reads on opponents in real time where the site rules allow it.
Trackers answer a question theory can’t: out of everything you do, what is actually bleeding money? You might discover you defend the big blind far too wide, or never fire a second barrel. Once a tracker surfaces a specific leak, you take it back to the trainer and drill the fix.
A few of the stats most pros watch closely, and what an off-baseline reading usually signals:
| Stat | What it measures | A common warning sign |
|---|---|---|
| VPIP | How often you put money in voluntarily | Too high means you play too many weak hands |
| PFR | How often you raise preflop | A big gap below VPIP means you call too much |
| 3-bet % | How often you re-raise preflop | Very low means you are too passive against opens |
| Fold to C-bet | How often you fold to a flop bet | Too high means you give up too easily |
| WTSD | How often you reach showdown | Extremes in either direction flag a leak |
None of these numbers is a verdict on its own. The value comes from comparing your figures against solid baselines and against your own results over a meaningful sample, then deciding which gap is costing you the most. That triage is the entire point of the tracker.
How the stack fits together
The three tools form a loop rather than a checklist:
- Solver sets the standard for a spot.
- Trainer drills it until the right play is reflexive.
- Tracker checks whether your real results improved, and points you at the next leak.
You don’t need every tool on day one. A beginner is better served learning fundamentals than paying for a solver subscription. But once the basics are in place, the players who improve fastest are the ones cycling through that loop, and the rep-building middle step is the one most people neglect.
It also helps to be honest about variance. Even a flawless study loop will not save you from long stretches of running bad, and confusing a downswing with a leak sends players chasing fixes that do not exist. Our guide to poker variance and downswings explains how to tell the two apart, which is itself a form of study most players skip.
If you want to see how today’s top players turn study into results, our roundup of famous poker players shows just how much of the modern game is built on disciplined off-table work, and the biggest poker tournaments are where that work gets tested.
The short answer to what pros use: a solver for theory, a trainer for reps, a tracker for honesty, and the discipline to keep running the loop.
Frequently Asked Questions
What tools do poker pros use to study?
Serious players rely on a small stack of three tool types, each doing a different job: a solver for theory, a GTO trainer for repetitions, and a tracker or HUD for finding leaks. No single program does everything, so pros treat the three as a system rather than a shopping list.
What is the difference between a poker solver and a GTO trainer?
A solver like PioSolver or GTO Wizard calculates the game-theory-optimal baseline and teaches you why a play is right, but it hands you a grid of percentages rather than a quick decision. A GTO trainer such as DEEPFOLD feeds you hands one at a time and scores your choices against that baseline, drilling the play until it becomes reflex.
Do I need a solver as a beginner?
No. A beginner is better served learning the fundamentals than paying for a solver subscription. Once the basics are in place, the players who improve fastest cycle through the loop of solver, trainer, and tracker, with the rep-building middle step being the one most people neglect.
What do poker trackers like PokerTracker and Hold'em Manager do?
Trackers import your hand histories and turn them into statistics such as VPIP, PFR, 3-bet percentage, fold to c-bet, and WTSD, answering which of your habits is actually losing money. The value comes from comparing your figures against solid baselines over a meaningful sample, then taking the biggest leak back to a trainer to drill the fix.
