I see a lot of talk about huds and trackers lately. I just started playing again a few weeks ago and I didn't really see much on this before. So to the questions.
What does a hud or tracker do? I keep seeing statements like,"Any serious player is using a hud."
I was never a high roller but I was consistently building my bankroll by reading betting patterns, remembering cards that people played in certain situations (if they went to the river) and counting my outs and using pot odds
to decide if I should be in the pot or not.
I'd just like to know if this is considered cheating or if it's not would it be in my best interest to get one of these.
Also is it free.
