What is a HUD & What Stats Should You Include?

Introduction

A HUD (Heads-Up Display) in Poker is a tool players use to enhance their decision-making process. It helps players make informed decisions based on solid data rather than relying on intuition or guesswork.

In this article, we will explore the ins and outs of Poker HUDs, the key stats they track, and how to use them to outsmart your opponents.

What is a HUD in Poker?

A HUD is a software tool designed to gather, organize, and present data about your opponents during online poker sessions. This transparent overlay appears on your Poker client, providing statistics like how frequently an opponent raises, calls, or folds in various scenarios.

Objective

A HUD aims to give players valuable insights into their opponents’ strategies, allowing them to make quick and calculated decisions.

Key HUD Stats in Poker

The specific statistics shown in a HUD can differ based on the Poker tracking software being utilized. However, here are the most common and essential stats:

VPIP (Voluntarily Put Money in Pot): This metric indicates the percentage of hands an opponent decides to play. A high VPIP suggests a loose player who gets involved with many hands, while a low VPIP signifies a tight player who only participates when they have strong or premium cards.

Pre-flop raise (PFR) indicates how often an opponent raises before the flop. A high PFR implies that the player is aggressive, frequently raising with a broad range of hands. In contrast, a low PFR indicates a more passive approach, typically raising only with strong hands.

AF (Aggression Factor): This metric evaluates a player's level of aggression by comparing how often they make aggressive moves, such as raises and bets, against passive actions like calls and checks. A higher Aggression Factor suggests the player is more prone to betting and raising, whereas a lower factor indicates they are inclined toward calling or checking.

Continuation Bet (C-Bet): This metric indicates the frequency at which a player follows up their pre-flop raise with an additional bet on the flop. A high C-bet percentage reflects aggressive play after the flop, whereas a low percentage suggests that continuation bets are likely made only when holding strong hands.

Went to Showdown (WTSD): This statistic indicates the percentage of hands an opponent plays all the way to showdown. A high WTSD signifies that a player is more inclined to take their hand to the river, whereas a low WTSD implies they tend to fold before reaching this stage.

3-Bet Percentage: This measure indicates how often a player re-raises in response to another player's raise. A high percentage implies an aggressive strategy, showing that the player frequently raises both when they have the positional advantage and without it. Alternatively, a low 3-bet percentage indicates a more passive playing approach.

 Fold to Continuation Bet: This statistic reveals how often an opponent folds when confronted with a continuation bet on the flop. If they frequently fold in this scenario, it might mean they typically don’t have strong hands post-flop, making them vulnerable to bluffs. 

Call Open Raise: This metric shows how often opponents call a raise from their position in the blinds or elsewhere at the table. A high percentage suggests the player is more passive and will call with a wider range of hands.

How to Use HUD Stats in Poker

Below are examples of how you might use various stats from the HUD:

Example 1: Playing Against a Tight Player

An opponent has the following stats displayed on your HUD:

• VPIP: 18%
• PFR: 15%
• AF: 2.0

These stats indicate that the player is tight (low VPIP) and aggressive (high PFR). They only play strong hands and raise frequently. The best approach here would be:

• Play tight. Only play premium hands against this player.
• Avoid trying to bluff them too often, as their aggression factor (AF) indicates that they will likely call with decent hands.
• When you have a strong hand, increase your value betting, as they will likely stick around with top pairs or better.

Example 2: Exploiting a Loose-Aggressive Player

You have the following stats on an opponent:

• VPIP: 45%
• PFR: 25%
• AF: 5.0

This player is loose-aggressive (often called a ‘LAG’ player). They are playing a wide range of hands and betting aggressively. The best way to exploit them is:

• Play in position and call more frequently with hands with good potential post-flop (for example - suited connectors, small pairs).
• Be cautious with bluffs. Since they are aggressive, they may call or raise your bluffs more often.

Example 3: Playing Against a Passive Player

Consider an opponent with these stats:

• VPIP: 25%
• PFR: 6%
• AF: 1.2

This opponent is tight and passive, usually calling with a small range of hands and rarely raising. You can adjust your strategy by:

• Raising more frequently to isolate them and take control of the pot.
• C-betting more often when you have a position, as passive players tend to fold when faced with aggression.
• Be careful about slow-playing. Since they rarely raise, you can extract value from your strong hands by betting for value rather than checking.

Popular HUD Software for Poker

Here are several of the most popular choices:

• PokerTracker: This robust tool provides an in-depth analysis of your gameplay, including hand histories and detailed statistics on opponents. It is among the most popular HUDs for players at all skill levels.
• Holdem Manager: Similar to PokerTracker, this software offers extensive tracking and statistical tools and a customizable HUD. It is praised for its intuitive interface and strong analytical features.
• DriveHUD: A relatively newer option that has quickly gained popularity. DriveHUD offers a clean interface and focuses on delivering an easy-to-use experience for players of all skill levels.

Should You Use HUDs?

While HUDs are legal in many online poker rooms, some platforms have banned them. They have established rules that limit or prohibit the use of third-party tracking software in specific types of games, including tournaments. It is essential to adhere to your Poker room’s terms and conditions as violating them could result in your account being suspended or permanently closed.

Some argue that using a HUD creates an unfair advantage for players. While it aids experienced players in making more informed decisions, recreational players, who generally don't employ these tools, might be disadvantaged.

Common Mistakes Made While Using a HUD

While HUDs are powerful tools, they can also lead to mistakes if misused. Here are some common pitfalls to avoid:

• Over-Reliance on the Stats

Players might become overly reliant on the statistics shown in their HUD, believing that these figures will consistently offer the correct solution. Although stats are beneficial, it is crucial to recognize that they don't reflect every subtlety of an opponent's behaviour. Always balance stats with good poker instincts and an understanding of the situation on the table.

• Not Adjusting Based on HUD Data

The real power of HUD stats comes from adjusting your strategy based on the stats in real time. A frequent mistake players make is failing to notice or adjust to an opponent's patterns. For instance, if you notice that a player often folds when faced with continuation bets (c-bets), raising your c-bet frequency against them would be beneficial.

• Utilizing Old Statistics

The statistics may be misleading if you don't regularly reset your HUD data or use it in a game where you have gathered insufficient hands on your opponents. Ensure that the sample size is large enough to provide reliable insights. Generally, you will need at least 50–100 hands on an opponent for their stats to reflect accuracy.
