How to Use a Poker HUD

A HUD (heads-up display) overlays your opponents' statistics on the online table, drawn from your tracking database. Used well, it turns a sea of hands into clear, exploitable reads. Used badly, it's a distraction or a crutch. The goal is to convert a few key stats into adjustments.

The core stats

A handful of numbers do most of the work:

• VPIP (voluntarily put money in pot): how loose they are preflop.
• PFR (preflop raise): how aggressive they are preflop. The gap between VPIP and PFR shows how often they just call.
• 3-bet %: how often they re-raise preflop.
• Fold to c-bet / fold to 3-bet: how exploitable they are postflop and to aggression.
• Aggression frequency: how often they bet/raise vs. call.

Reading player types fast

• High VPIP, low PFR → a loose-passive station: value-bet relentlessly, don't bluff.
• Low VPIP, low aggression → a nit: steal their blinds, fold to their big bets.
• High VPIP and high aggression → a maniac: tighten up, let them bluff into you, trap.
• High fold-to-c-bet → c-bet them more; low fold → bet for value, not bluffs.

Sample size matters

Small samples are noise. A "70% fold to 3-bet" over five hands means nothing; over hundreds it's a green light to 3-bet bluff. Wait for enough hands before trusting a stat — the same signal-vs-noise principle that governs all reads.

Don't over-rely on it

A HUD informs decisions; it doesn't make them. Combine the numbers with the actual hand, the board, and the situation. Strong players use the HUD as one input, not a substitute for thinking.

The takeaway

Learn a few core stats, use them to classify opponents quickly, respect sample size, and convert reads into clear adjustments — bluff the folders, value the stations, trap the maniacs.
