Leak Explorer Tutorial

Or how to win more money by comparing your stats to winning players

Leak explorer

  • Finds potential leaks by comparing your stats with the stats of winning opponents in your database
  • Shows you which hands winning opponents play more or less often than you
  • Shows how your play changes over time

Explore Preflop Leaks

When you open Range Wizard you have three options.

Home view

Select “Explore Preflop Leaks”. Range Wizard will begin searching for leaks.

When it finishes you see a list of possible leaks on the left and a detailed view of the selected leak on the right.

Preflop leaks

The list of leaks is sorted by leak size.

The right view shows details about the selected leak. It has 3 views.

  • Overview – provides a quick visual of the leak
  • Hole Cards – compares hand ranges between you and the opponents (preflop only)
  • Time based views – allows you to see how your hand range changes over time


The overview shows how your hand range compares to the winning opponents average hand range.


A list of position is shown on the left if position data is available.

The chart on the right provides a visual representation of the leak.

Hero and Opponents

The large blue dot represents the hero.

The horizontal (x-axis) position of each dot is the hero’s all-in adjusted EV.

The vertical position (y-axis) is each hero’s stat value in percent.

The green dots represent the winning opponents that were included in the analysis. Hovering your mouse over a dot will display that player’s details.

Opponent details

Hero and Opponents Average Stat Value

The blue horizontal line is the Hero’s stat value. The green horizontal line is the average stat value of the opponents.

Hero and opponents average stat values

The actual stat values are shown on the y axis.

The yellow band is the difference between the hero’s value and the average opponent value. The band is yellow if the hero is looser than the average opponent value and purple if the hero is tighter than the opponent average.

Opponent Standard Deviations

The dark green background represents the average opponent value plus or minus 1 standard deviation.

The light green background represents the average opponent value plus or minus 2 standard deviations.

Standard deviations

From Wikipedia:

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.[1] A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.

In other words, the more the opponents agree on the “best” value, the smaller the standard deviation.

The size of the leak is computed using the difference between the hero’s value and the average opponent’s value in standard deviations. This provides a convenient way to compare the leak size between different stats.

Hole Cards View

The Hole Cards view is basically the same as report hole cards view. The only difference is it always show the selected leak’s stat so you cannot select a different stat.

Hole cards view

Check “Show differences” to see how your hand range compares to the average winning opponents hand range.
