When playing online, what I use are notes and tags.
I don't use Huds, in truth it is almost certainly possible that they will help you define a situation, but I really don't like using them because for me the essence of the game is lost.
What's more, I don't believe that a hand is defined by a Hud, nor do I believe too much that you have to play as the program says, for example.
If I use the equilab to review the hands, to see where I could have made a mistake in a call or in a hand with respect to its
equity.
