Definition of HUD
The letters HUD means "Heads-Up Display". The HUD is what appears on your online poker table when you have a tracker. The tracker will record the hand historys you play, it will accumulate statistics to give you a complete report on each player. But in order for this information to be really useful, you need to be able to use it in real time at the poker table. The HUD is a small rectangle that you will see displayed on your table with all the information about your opponents.
The HUD, a powerful tool to win at poker!
If your online poker room allows players to use a HUD, you should use one. You will get a HUD if you buy the tracker like Pokertracker 4 or Xeester for example. When you play several tables at the same time, it's impossible for you to keep track of everything the players have done. You can't always tell who plays a lot of hands, who is conservative, who bets consistently on the river, who 3bet a lot, who calls a lot, etc. Your HUD will give you this information. It will be possible for you to organize the specific information you want to see displayed at the poker table in your HUD.
