I have been a big proponent of using a HUD for many years especially at the micro stakes. It can be very difficult to keep track of dozens of different players across several tables.
This information is incredibly useful to have when you are playing online poker especially if you plan to play multiple tables. A HUD by the way is short for 'heads up display' which is a program that allows you to collect data on your opponents and put it right on your screen in online poker.
People ask me all the time what is the best poker HUD to use in 2023.
