The preflop stage is where many of the most valuable poker reads are collected. While HUDs display statistics such as VPIP, PFR, and 3-Bet percentage, they don't tell you which hands an opponent actually plays from each position. Good preflop notes reveal the information that statistics cannot.
Suppose your HUD shows:
Those numbers look useful, but they don't answer important questions.
A player with a 25% VPIP may only open premium hands from Early Position while another opens almost twice as wide. The HUD gives both players similar statistics, but your strategy against them should be completely different.
Record which hands an opponent opens from:
Example:
EP: AQ+ 99+ BTN: Any Ace 54s Q9o
Don't simply write "3-Bet 8%". Record where those 3-Bets come from.
EP: QQ+ AK BTN: A5s KTs 76s
Some players steal every button. Others never attack the blinds.
BTN Steals 80% SB Steals Any Ace Never steals
One of the most valuable notes. Record the exact hands that reach showdown.
Calls 3B: KQo QJs 88 AJs
4B: AA KK AK Jam: QQ+ AK or Jam: 99+ AQ+
BB Calls: J7s A2o 54s SB folds too much.
HUDs show frequencies. Poker notes show actual decisions. Knowing an opponent has a 3-Bet percentage of 8% is useful, but knowing that all of those 3-Bets come from the Button with suited wheel aces is far more valuable. Likewise, a VPIP of 25% doesn't tell you whether an opponent is opening A5s from UTG or simply stealing every Button. Poker notes provide context that statistics cannot.
The goal of preflop note taking is to identify an opponent's real ranges rather than relying only on percentages. Record opening ranges, 3-Bet ranges, blind steals, blind defense, 4-Bets, all-in ranges, and hands shown at showdown. Over time, these observations become one of the most valuable tools for exploiting regular opponents.
