re: Poker & How many use a HUD and if not, how did you wean yourself off?
I enjoy a HUD, but the problem you might be having is that you're no longer using other non HUD skills that you should still be using with your HUD.
For example, if you're 6 hands in, and your opponent has opened all 3 hands from the SB, you'd see a 100% open raise on his button. But there is a huge difference between you seeing KK, AA, AK in those 3 hands, and 73o, K2o, J3. If you've seen 3 hands and they are all strong, you absolutely should not assume this opponent is opening near 100% of his hands on the button. If you've seen the weaker set of 3 that I mention, then you probably can assume he's opening a very wide range of hands on the button.
My point is, the HUD is great for giving you access to a lot of information quickly, but you still need to pay attention and understand the types of hands you're seeing over these samples, otherwise you're going to make a ton of poor decisions using your HUD (especially when you have a smaller sample of hands).
Also, the stats you have on your HUD is important too. You may see someone opening 20% from one position, so you assume their range on the turn (after they had opened preflop) is mostly those 20% of hands, minus some other hands that might not usually cbet. But if you missed info previously that shows them taking a different action with a lot of weaker flop hands, you're now assuming they have too wide a range on the turn (and a call or raise would be against a much stronger range than you assume your opponent has).
Cliffs - Using the HUD properly is also very important, it can hurt you if you just read #s and make decisions without taking into account anything else.
