re: Poker & TO HUD OR NOT TO HUD?
Personally, I choose not to HUD. It's not that I have anything against them. I've played around with them in the past, when there were free trial offers for various ones. I also used the free one offered on Carbon Poker
when I remembered. My initial opinion about them was that they were interesting, but I could almost always get a read on my opponents much faster than the HUD could just by paying attention. I figured that they would become more useful as they accumulated more data over time.
From what I have heard from players that do use them, they are most useful to players who multi-table a lot, playing several S&Gs or cash game tables at a time. It makes since to me that with the right stats displayed, it would be possible to get an idea how someone might play or at least some of their tendencies at a quick glance.
I tend to be more of a tournament player. When I play cash games, my preference is to play at least $50NL up to about $400NL. At those stakes, I prefer to focus on one table at a time. Since I do tend to only play one table at a time, I find that paying attention and keeping good notes precludes the necessity to use a HUD.
