HUD (Heads-Up Display)

What Is a HUD?

A HUD is the professional online poker player’s most important tool outside of their own brain. It sits transparently on top of the poker table, showing key statistics next to each opponent’s name — how often they raise preflop, how frequently they continuation bet, how aggressive they are on each street, and dozens of other metrics that inform your decisions in real time.

Where a room supplies permitted hand histories, a tracker may import them for analysis. Record the sample for each statistic: 1,000 total hands do not imply 1,000 chances to face a three-bet. Rare actions can remain uncertain even in a large overall database.

PokerTracker, Hold’em Manager and DriveHUD are separate product names, not stages of a rename. Before buying software, check the developer’s supported room and regional-client list, then check the room’s current tool policy. Import support does not itself authorize live use.

How It Works

Hand History Import: The poker room generates a text file for each hand played. The HUD software monitors the designated folder and automatically imports new hand histories in real time.

Database Storage: All hand data is stored in a local database (usually PostgreSQL). Over months and years, this database can contain millions of hands and detailed profiles on tens of thousands of opponents.

Stat Calculation: The software calculates hundreds of statistics from the raw hand data. Common stats include VPIP (voluntarily put money in pot), PFR (preflop raise percentage), 3-Bet %, fold to 3-bet, c-bet frequency, aggression factor, and WTSD (went to showdown).

Overlay Display: Selected stats are displayed next to each player’s name on the table. The display is fully customizable — you choose which stats to show, the font size, color coding, and layout.

Pop-Ups: Clicking on a player’s HUD panel opens a detailed pop-up with dozens of additional statistics, broken down by position, street, and situation. This is where deep analysis happens mid-hand.

Example

In a hypothetical permitted HUD sample, an opponent has VPIP 22%, PFR 18% and Fold to 3-Bet 58% across the relevant recorded opportunities. The last figure is an observed sample rate, not a 58% guarantee for your next three-bet. An early-position opening range, your sizing, remaining players and uncertainty can change the decision with Ace-Jack suited. Inspect the statistic’s denominator and context before using it.

Where HUDs Are Allowed

Use calculation software for off-table study. The PokerStars tools policy prohibits advanced GTO, ICM and equity tools while any client is open; its limited permission for simple starting-hand charts is not permission for live solvers. The GGPoker security policy prohibits charts of any kind during play. Check the rules of your exact room, regional product and tool before opening it.

HUD policies vary significantly between poker rooms, and this is a critical factor for players who rely on these tools.

• PokerStars: read the applicable tools policy and restrictions; do not assume every feature of a compatible tracker is allowed.
• GGPoker: check its security policy separately rather than importing PokerStars permissions. Built-in room features do not authorize external live assistance.
• 888poker: verify the current regional client, hand-history access and permitted features before choosing a HUD.
• PartyPoker: check current product rules and table format rather than relying on a historic permission or ban.

FAQ

Do I need a HUD to win at online poker?

No tool guarantees a win, and some games restrict external overlays. Start with permitted observation. A measurable advantage cannot be inferred merely from owning a HUD.

Which HUD software is best?

There is no universal best HUD. Compare the separate PokerTracker, Hold’em Manager and DriveHUD products by verified support for your exact client, permitted features, cost and usability. This article does not verify current prices or regional compatibility. Do not buy software on the assumption that it will work in every room.

Is using a HUD considered cheating?

No. Where permitted by the poker room, HUDs are a legitimate tool. They only organize information that is already available through hand histories. The poker room itself generates these histories and makes them accessible to all players. However, the ethical debate continues, and the trend across the industry is moving toward restricting or banning HUDs to protect recreational players.
