HUD
also called heads up display
A HUD is a display that overlays statistics about each opponent onto the table, drawn from the hands you have already played against them.
The numbers it shows are frequencies, not reads: how often someone puts money in before the flop, how often they raise, how often they reach a showdown. Each one is only meaningful once enough hands have gone by, and a figure taken from twenty hands says nothing at all.
Many rooms restrict or ban them, and the habit they encourage is worth watching in any case. A statistic tells you what someone usually does, and the hand in front of you is decided by what they are doing now.
an example
your cards
The display shows an opponent playing 48% of hands and raising 6% of them. That gap says they call a great deal and raise almost nothing, so ace jack is a hand to raise for value against them rather than one to be careful with.
This example is made up. The real one is in your own hand history: find hud in your own hands and see how often it came up and what it cost you.
