The Calling Station: Fold to a passive player's rare raise

They have called 14 of your bets and raised twice. Both raises turned over two pair or better.

A passive player's rare raise means strength. On a dry board like this it raises only two pair or better and never raises a draw, so top pair is behind.

Recommended action: Fold

Both raises you saw tonight were two pair or better, and this is the same raise. Top pair is behind, so folding saves the $48.

The Maniac: Raise for value against a wide opener

When 3-bet, they folded four times and called with K-9 suited and 7-6 suited.

This opener folds about two thirds of the time to a 3-bet, and most hands that call are behind ace-queen.

Recommended action: 3-bet to $26

They open wide and fold most of it to a 3-bet. The hands that call, like the K-9 and 7-6 you saw, are behind ace-queen.

The Nit: Size bluffs up against a player who folds more to bigger bets

They have folded to about half of your flop bets, and more often the bigger you bet.

This player folds more as the bet gets bigger. Here a pot-size bet folds about 79% of their range, against 65% for $7.

Recommended action: Bet $13

They fold more to bigger bets: about 79% of their range folds to $13, against 65% to $7. With six-five and no pair, the bigger bluff earns more.

Why an exploitative poker trainer?

A GTO solver balances your whole range so that no opponent can exploit it. Real opponents do not play equilibrium poker. Equilibrium leaves their mistakes undefined. Poker Shark starts from the opponent instead: six opponent styles, each a distinct and common playstyle. Our Best Response Engine finds the play with the highest expected value against that style. Every recommendation comes with the range the Best Response Engine assumes, along with the EV computed for every action, so you can be confident running your next three-barrel bluff or value betting thinly on the river.

GTO trainers teach you the play no one can exploit. An exploitative trainer teaches you the play that exploits the player in front of you. That is the core idea behind exploitative poker strategy. At low and mid stakes the second skill is worth significantly more, which is why this page pairs with realistic poker practice in a single loop. It is also the habit that separates a poker shark from the rest of the table.

GTO trainers

  • Drill the play no opponent can exploit
  • Adjusting to a real opponent means node locking by hand: slow, easy to get wrong, and every unlocked node still assumes perfect play
  • Balance is the goal, so the opponent's mistakes go uncollected
  • Assumes the opponent plays perfectly, which nobody does at your stakes

Poker Shark

  • Find the play that earns the most against the player in front of you
  • Adjust to each style's specific leaks, street by street
  • The opponent's mistakes are the target, including the ones that show up later in the hand
  • Five opponent styles modeled on real players, plus GTO

If you're weighing the two approaches, the full argument is in why exploitative poker beats GTO at small stakes. And if solver talk is new to you, what a poker solver does covers the basics in plain language.

A live poker trainer for cash games

Live cash games are where the player leaks and tendencies are easiest to spot and most expensive to misread. The tight-passive player who suddenly bets big is usually protecting a strong hand and does not want a draw to get there. The loose-passive player who calls two streets with top pair is not folding the river either. Some regulars continuation-bet every flop, or use one size for value and another for bluffs, and the sizes tell you what they are trying to do.

Poker Shark trains those reads at cash-game stakes from $1/$2 to $500/$1,000, at 100 and 200 big blinds deep, against the same six styles you meet in the room. You practice the decision, study the range behind it, and learn to crush the table.

It is a trainer for before and after the session, never during a hand. Using it, or any tool like it, while you play breaks the rules of every site and card room.

A structured path from fundamentals to mastery

The level 1 card in the Arena lobby: Loose Passive, in position, 100 big blinds, $1/$2 stakes, with the player pool bar and the Start Run button.

12 levels. 6 opponent types. Increasing difficulty.

The arena is structured as a 12-level progression from $1/$2 to $500/$1,000, built around the step-by-step exploitative framework. Each level is led by one opponent type.

L1-2

Loose Passive

Calls too much, rarely raises

L3-4

Loose Aggressive

Wide ranges, early-street pressure

L5-6

GTO

GTO-style, only small leaks

L7-12

Advanced

200bb deep, then the Regular and the Adaptive

Replay any hand. Take over any decision.

Every hand is saved automatically. The replay system lets you step through each action and see exactly what happened. The takeover feature lets you branch into an alternate line at any decision point.

How poker hand review with takeover works

Your leaks, measured and ranked

Poker Shark tracks 19 leak stats and measures each against a baseline. It tells you how far off you are, how confident the signal is, and how severe the leak.

Overfolds to 3-bets

Baseline: 45% Flag: >60%
MAJOR

C-bets too wide

Baseline: 55% Flag: >80%
MODERATE

Never bluffs river

Baseline: 25% Flag: <5%
MODERATE

Scout your opponents before you exploit them

The scouting panel shows each opponent's key stats as you play. Confidence levels tell you when you have enough data to trust the read. As you accumulate hands, the picture sharpens.

Who this is built for

Warming up

Play 10-15 hands before a session. Get your reads sharp and your decision-making calibrated without risking money before you're in the zone.

Studying between sessions

Review your hands, branch alternate lines, and work on specific skills. Thirty minutes of focused training teaches more than three hours at a play-money table. See how Poker Shark compares to other training apps.

Moving up in stakes

Before you risk bigger buy-ins, train against tougher opponents. Levels 7-12 play 200bb deep. The Regular leads levels 9 and 10, and the Adaptive, who studies your saved hands, leads levels 11 and 12.

Questions about poker training

What is the best exploitative poker trainer? +

It depends on the question you want answered. If you want equilibrium charts and balanced-frequency drilling, GTO tools do that well. Poker Shark answers a different question: what is the strongest play against the specific player in front of you? You get hands against six opponent archetypes with measurable tendencies, hand replay with takeover, and automatic leak detection, so you practice finding and punishing each type's leaks.

Is poker training worth it? +

Yes. Learning only at real-money tables means paying for every mistake. Practicing against realistic opponents gets you the same reps without the cost.

What's the difference between training and coaching? +

Coaching gives you someone else's analysis of your play, typically $100-300/hour. Training gives you the reps and feedback to develop your own reads and instincts. Both have value, but training builds the pattern recognition that coaching alone can't replicate.

How is Poker Shark different from GTO trainers? +

GTO trainers teach you to play a balanced, unexploitable strategy. Poker Shark teaches you to exploit opponents who aren't balanced, which is nearly everyone at low and mid stakes. You face opponents with specific, measurable tendencies and learn to adjust your strategy to profit from their patterns.

What is the best poker training for cash games? +

Training that reproduces the decisions cash games actually present: deep stacks, no blind pressure, and opponents who stay the same for hours. Poker Shark is built only for cash games, six-max at 100 to 200 big blinds, against five opponent styles modeled on real players and a GTO opponent.

Is Poker Shark a free poker trainer app? +

Poker Shark runs in the browser on desktop and phone with nothing to install, and it is free during early access. No credit card.

Can I use a poker trainer during a live game? +

No. Card rooms and online sites forbid real-time assistance, and Poker Shark is built for study before a session and review after it. Using it, or any tool like it, while you play breaks the rules of every site and card room.

Train the skills that win at real tables.

12 levels. 6 opponent types. Every hand saved. Leaks detected.
