Leak Explorer Tutorial

Win more by comparing your stats to winning players

Leak Explorer is an HM3 app that:

  • 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
  • Shows how your play changes over time
  • Shows you how your play varies by position

Start Leak Explorer

To start Leak Explorer, select Enable Leak Explorer on the HM3 Apps menu.

Home Page

Leak Explorer will open and display the home page.

Searching for leaks

The home page allows you to select

  • How many current player hands to include
  • Which game types and stakes to include
  • Which winning players to include

Leak Explorer is already searching for leaks in the background using the home page settings. If you click on the Leaks tab at the top of the window you will see it has already found some leaks.

Whenever you change a setting on the home page, Leak Explorer will begin searching for leaks using the new settings.

Use last current player hands

This option limits the number of current player hands.

Use last current player hands

Select this option when you want Leak Explorer to use the most current hands in your database. Type the number of hands you wish to use.

Deselect this option to use all current player hands.

Whenever you change this option, the game types and stakes list below will be updated to reflect only the game types and stakes available in the selected hands.

Game types and stakes

Below the last current player hands option is a list of available game types.

Game types

Check or uncheck game types to select which you wish to include in the leak search.

Click the arrow to the left of a game type to see which stakes are available for that game type.

Game types and stakes

Here you can select which stakes to include in the leak search.

Select Winning Players

The right side of the home page shows a list of winning players in your database.

Winning players

Here you can select which players to use in the leak search.

Use top players

When Use top players is selected, Leak Explorer will use the top players in the list to find leaks.

Use top players

Type a number in the box to change the number of players used.

Sorting the winning players

Clicking on a column header will change the sort order of the players, which also changes which players are used to find leaks.

Sort by total winnings

Note that playing style is a number that measures how closely the winning player’s playing style matches the current player, based on VPIP, PFR, and AGG%. Sort by this column if you wish to use players that play similarly to yourself.

Customizing the selected winning players

You can customize the selected winning players by checking or unchecking the Select box in each player’s row.

Customizing the selected winning players

Only the selected winning players will be included in the leak search.

Leaks Page

Select the Leaks tab at the top of the window to view the leaks page.

Leaks page

If you changed any of the search options on the home page, Leak Explorer may still be searching for leaks in the background. It will update the list of leaks as it finds more leaks.

The first category contains all potential leaks found for the selected street.

The list of categories is sorted by the leak size of the leaks it contains. The red icons indicate the largest leaks, yellow icons are medium leaks, and green icons are small leaks.

Leak Properties

The right view list properties of each leak in the category.

Leak properties

These properties include:

  • Stat – the name of the stat
  • Stat Value- the current player’s stat value or winning opponents’ mean stat value
  • Opportunities – the number of times the current player or winning opponents had the opportunity to take the action
  • Win Rate – the current player’s win rate or winning opponents’ mea win rate
  • Stat Diff in SD – the difference between the current player’s stat value and the winning opponents’ mean stat value measured in standard deviations
  • Win Rate Diff – the difference between the current player’s win rate and the winning opponents’ mean win rate
  • Leak Size – a combination of Stat Diff, Win Rate Diff, and Opportunities

Explore a Leak

Click on the arrow to the left of a category to expand the category.

All leaks expanded

The number in parentheses to the right of the stat indicates the leak size.

Click on the leak you want to explore. In this tutorial, we will explore the “Defend vs 1 Limper” leak.

Exploring a leak

If the stat includes positional stats it will expand to show them.

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

  • Overview – quick visual of the leak
  • Positions – stat values broken down by position (where available)
  • Hole Cards – compares hand ranges between you and the opponents (preflop only)
  • More Charts – additional time-based charts

Overview

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

Leak overview

The blue horizontal line is the hero’s stat value. The green horizontal line is the winning opponents’ mean stat value.

Current player and winning opponents’ mean stat values

The blue arrow indicates the direction of the difference. Up is looser than the mean, down is tighter than the mean.

Each green dot represents an opponent who was included in the comparison. The horizontal (x-axis) position of each dot is the opponent’s all-in adjusted expected value per 100 hands (All-in Adj bb/100). The vertical position (y-axis) is each opponent’s stat value.

Hovering your mouse over a dot will display that player’s details.

Opponent details

The winning opponents’ mean stat value is weighted so that opponents with higher win rates and opportunities contribute more to the mean. The total weight is the percentage of the stat value that the opponent contributes. Opponents with win rates less than the current player’s win rate contribute zero percent.

Hero and Opponents Mean Stat Value

The dark green background represents the opponents’ mean value plus or minus 1 standard deviation.

The light green background represents the opponents’ mean value plus or minus 2 standard deviations.

Opponents’ mean +/- 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 closer the opponents are to the mean 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.

Positions

The Positions view breaks the leak down by position when available.

Positions view

Where each column is the same as in the category view except the first column is the position instead of the stat name.

You can explore a positional leak by double clicking in the positions view or selecting a positional leak in the left view.

Hole Cards

The Hole Cards view compares the hero’s hand range to the winning opponents’ hand range.

Hole cards view

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

Show differences

Blue hands are hands the current player plays more often that winning opponents. Green hands are hands the current player plays less often. Gray hands are hands both play about the same.

More Charts

The More Charts view shows how the hero’s stat value changes over time.

The Day chart shows the hero’s stat value grouped by day.

Day chart

The Day of Week chart groups the hero’s stat value by the day of the week.

Day of Week chart

The Hour of Day chart groups the hero’s stat value by the hour of day.

Hour of Day chart

The Session Minutes chart shows how the hero’s stat value varies during sessions.
