Why you can't fix what you can't see

The mistakes that cost you the most are the ones you stopped noticing. Finding them takes an outside read on your own game, the same way you would scout an opponent. It is the core of playing exploitative poker, turned on yourself.

You are blind to your own leaks

The mistakes that cost the most feel normal, because you make them every session. An outside read is the only reliable way to catch them.

Results hide leaks

A losing session can be run-bad, and a winning one can be full of mistakes that got paid off. Win rate alone will not tell you where you bleed. The pattern across many hands will.

You fix the wrong thing

Without data, players patch whatever lost the last big pot. Often that spot was fine and the real leak is somewhere quiet, like folding the turn too often. Fixing the wrong thing wastes the work.

Five common poker leaks to check first

Start with patterns that repeat across hundreds of decisions. Use the signal to identify the leak, understand why it costs money, then practice one specific correction.

01

Playing too many hands preflop

Signal: Your 6-max VPIP stays above roughly 35% over a meaningful sample.
Why it costs money: Weak starting ranges create more dominated hands and difficult postflop decisions.
How to fix it: Remove the weakest hands from each position and judge the change over at least 100–200 hands.

02

C-betting on autopilot

Signal: Your c-bet frequency stays above 75% or below 40% regardless of board texture.
Why it costs money: You either fund check-raises with low-equity bets or surrender pots one small bet could win.
How to fix it: Let range advantage and board texture determine whether you bet, then choose a size that fits the range.

03

Folding too much on the river

Signal: You fold to river bets more than about 60% of the time.
Why it costs money: Observant opponents can bluff wider because too few bluff catchers reach showdown.
How to fix it: Check whether the betting line represents enough value combinations before folding every marginal made hand.

04

Not adjusting to opponent type

Signal: Your ranges, bet sizes, and bluff frequency barely change between loose, tight, passive, and aggressive players.
Why it costs money: A strategy built for one tendency gives up value or burns bluffs against its opposite.
How to fix it: Classify the opponent, choose one evidence-backed adjustment, and review whether it targeted the observed mistake.

05

Ignoring position

Signal: You play similar starting ranges from early position, the blinds, cutoff, and button.
Why it costs money: Out-of-position hands realize less equity and create harder decisions with less information.
How to fix it: Tighten early-position and blind ranges while taking more profitable opportunities from the cutoff and button.

The kind of leaks Poker Shark flags

19 leaks are tracked across preflop and postflop, each with a severity rating and the hands that prove it. A few of the usual suspects:

Overfolds to 3-bets

You give up too many pots to a re-raise, so aggressive opponents can 3-bet you light and print.

Passive turn play

You check and call where a bet would fold out equity or build the pot with your value hands.

Misses river value

You check back or under-bet rivers with hands a worse holding would have paid off.

Calls down too light

You pay off big bets with bluff-catchers that beat almost nothing in their range.

Predictable sizing

Your bet sizes tell the table when you are strong, so observant opponents stop paying you off.

Too passive preflop

You limp and flat where a raise would take control and put the pressure back on them.

How the leak finder works

01

Just play

No setup and no importing. Every hand you play in the training arena feeds your profile automatically.

02

Stats are pot-weighted

Big bets count more than min-bets, so the numbers reflect where real money moves, not just how often you click a button.

03

Leaks get flagged with evidence

Each leak comes with a severity rating and the specific hands that prove it, so you can see it, not just read a number.

04

Fix it and watch it fade

Drill the spot, replay the hands, and keep playing. As your decisions change, the leak's severity drops. That is your proof it is fixed.

Questions about finding leaks

What is a poker leak? +

A leak is a recurring mistake that costs you money over time: calling too wide, folding to too much pressure, missing thin value on the river. Every player has them, including strong ones. Finding yours is the fastest way to raise your win rate.

How do I find my poker leaks? +

Track your play over a real sample and look for patterns, not single hands. Poker Shark does this automatically for the hands you play in the Arena, flagging 19 specific leaks with a severity rating and the hands that prove each one, so you see the biggest drain first.

What are the most common poker leaks? +

Playing too many hands preflop, c-betting without considering board texture, folding too often on the river, failing to adjust to opponent type, and ignoring position are five common poker leaks. The checks below show how to recognize and fix each one.

How do I fix a poker leak once I've found it? +

Isolate the spot and drill it. Replay the hands that flagged the leak, take over the decision, and play the better line until it is automatic. Then keep playing and watch the leak's severity drop as the evidence changes.

Find the leak. Fix the leak. Move up.
