8 Poker Leaks You Can Diagnose in 60 Seconds

Most poker leaks do not feel like leaks. They feel like habits, and habits feel like strategy. The fastest way to find one is not a database review, it is a yes-or-no question you can answer honestly in about five seconds.

Here are eight of them. Each is a question, a number from a real solve that shows what the habit costs, and the one thing to do about it. Answer yes to any of them and you have found something worth a session of study.

1. Do you open the same number of hands from every seat?

The number: in a solved 6-max cash game at 100bb, under the gun opens 18.7% of hands and the button opens 43.3%. That is not a small widening. The button plays well over twice as many hands as the first seat.

The fix: stop thinking of one opening range with adjustments. There are five different ranges, and the gap between the first and last is the single largest edge available preflop. The position-by-position blueprint has all five.

2. Do you always raise or fold the small blind?

The number: that same solve limps 20.5% of the time from the small blind, alongside a 33.1% raising range.

The fix: this is the rare case where the popular rule ("never limp") is a simplification rather than the equilibrium, and it is a defensible one. Raise-or-fold is easier to execute and hard to punish. Just know that you are choosing a simpler strategy, not the optimal one, and that the solver is doing something else.

3. Do you check-raise based on how strong your hand is?

The number: on 9-7-2 with two hearts, the big blind's check-raise frequency with pocket sevens (middle set) is 20% against an under-the-gun opener and 91% against a button opener. Same board, same hand, same bet size. Only the opener changed.

The fix: before you decide what your hand is worth, decide what their range is. Strength sets whether you can raise. The opponent's range sets whether you should. Postflop+ drills exactly this kind of decision and grades it immediately.

4. Do you tighten everything when ICM kicks in?

The number: at a solved final table with every stack on 12bb, the button jams 26.1% at chip EV and 41.8% under ICM. It gets looser, not tighter. Meanwhile the big blind's calling range collapses from 26.6% to 8.5%.

The fix: ICM makes you a tighter caller and a looser shover. Most players apply the tightening to both halves and leave all the profitable shoves on the table. Work out your risk premium with the free ICM Calculator, then read the full push-fold breakdown.

5. Do you judge a PLO hand by its ranks?

The number: a mid or low pair with no suits opens 0.9% of the time from the hijack. Give the identical ranks two suits and it opens 31.8%, roughly 35 times more often.

The fix: read the suits before the ranks. In Omaha, double-suited is a category change rather than a bonus, and a pretty-looking rainbow hand is often not a hand at all. Which PLO pairs are actually worth playing has the full breakdown.

6. Do you c-bet at roughly the same rate on every flop?

The number: as the preflop raiser at 100bb, the cutoff bets 81% of its range on A-K-7 rainbow. Move to T-8-5 as an under-the-gun raiser and the same player checks 40% of the time, including pocket aces 73% of the time.

The fix: your c-bet frequency is a property of whose range the board hits, not of the fact that you raised preflop. When the caller's range connects better than yours, checking is the whole strategy, not a weak alternative. Both solves, hand by hand.

7. Do small bets make you fold?

The number: against a bet of one third of the pot, minimum defense frequency says you need to continue with about 75% of your range. Fold more than a quarter of the time and the bet prints automatically, whatever the bettor is holding.

The fix: small bets are cheap to call and expensive to over-fold against. Check your own threshold with the free MDF Calculator. One caveat worth keeping: MDF is a river baseline, and on flops where the board smashes the bettor's range you are allowed to fold more than it suggests.

8. Does a bad month make you rebuild your strategy?

The number: at realistic win rates, tens of thousands of hands of breakeven poker are a completely ordinary outcome. Not a downswing, just a flat graph for a very long time.

The fix: before you tear up a strategy, find out whether the sample says anything at all. The free Poker Variance Calculator runs your win rate and standard deviation and shows you the range of normal. If you do not know your own numbers to put into it, that is the actual leak, and Tracker+ is where you start recording them. How bad a downswing can get covers the rest.

Frequently Asked Questions

What is the most common leak in poker?

Playing the same opening range from every position. In a solved 6-max 100bb cash game the first seat opens 18.7% of hands and the button opens 43.3%, so a player using one range for both is either far too loose early or far too tight late, and usually both.

How do I find my poker leaks without a tracker?

Ask yourself diagnostic questions about your habits rather than reviewing hands. Habits like c-betting at a fixed rate, folding to small bets, or opening one range from every seat are visible without any database, and each maps to a specific fix.

Does ICM mean I should play tighter?

Only when calling. ICM tightens calling ranges sharply because the caller risks elimination, but that lost fold equity makes shoving wider correct. In one solved 12bb final table the button jams 41.8% under ICM against 26.1% at chip EV.

What is the best app to fix poker leaks?

It depends on the leak. Preflop range problems are a GTO Ranges+ job, postflop decision-making is what Postflop+ drills, looking up a specific board is Solver+, and Pot-Limit Omaha is PLO+. The free calculators cover the rest: ICM, minimum defense frequency and variance.

How long does it take to fix a poker leak?

A single leak with a clear fix, such as widening your button opening range, can be corrected in one study session and applied immediately. Habits that involve reading an opponent's range, like check-raising frequency, take repetition in a trainer before they show up at the table.

Pick one

Eight questions, and most players answer yes to at least three. That is normal, and trying to fix all three at once is how study time gets wasted. Choose the one that costs you the most in the games you actually play, spend a week on it, then come back and run the list again.

If you want the honest version of why fixes do not stick, why your study does not show up at the table is the companion piece to this one.
