This is a discussion on Is a HUD good or bad in the long run? within the online poker forums, in the Poker Software & Tools section; I've been playing online tournaments and cash games for a while now, and every time I consider using a HUD I have opted out and
I do understand why it would be better to not use poker track HUD. I noticed I had a harder time when playing live without the HUD so decided to stop using it. That was when I started to do better live. I forced me to concentrate on the game more.
I don't have live poker experience but you can benefit from a HUD in the long run 100%. If you buy a HUD with a replayer then you can review your entire sessions or specific(marginal) hands. I find it very helpful for your development as a poker player overall.
As far as it concerns online poker unfortunatelly it is essential to use HUD , I wish it wasn't or it got forbade to use it sometime in the future . Now if it affects your ability to play poker on the log run especially live (maybethis is what you say) , I don't believe it personally , I think you keep on playing the same , good or bad .
HUD doesn't gather anything that human's eye / mind can't notice, if you play one table live/ online and pay attention, you can definitely do just fine without HUD.
When HUD is useful, is when you're multirooming / multitabling online, different tournaments, different opponents, different stages of tournaments at different tables - it's good to look quickly on stats and don't put a ton of attention/ concentration to try and recall what this CO on table 6 is playing like / what his stack is / what stacks of whole table are /should you repush or fold cuz it's bubble here while the game at table 3 has just started. You can use your time on actually thinking about your decisions and not trying to figure out this basic stuff. Obviously when you're playing one table live, you already know all of this before facing a decision, as you don't have any other sources of different information that distract you from this table. Therefore it doesn't mean that you posses some special skill if you can play fine one table without HUD live or 2-3 online.
In addition, if you're multitabling online after the same amount of time you will play a significant amount more hands over the same time you will do playing live, thus you can using your HUD to analyze your own game. Around 100k hands are more or less enough to find some tendencies and patterns and correct them if needed. How many years you will play this amount of hands live? Variance play a huge role in live poker especially in MTT.
So HUD is neither good nor bad in the long run. It's essential if you're multitabling; it's useless if you don't know how to play. Maybe it will help to a solely online player to start playing a couple of tables online without HUD if he's planning on transitioning to play live only, just to get used to keeping all the info in your head, and that's it as I see it.
You will be at a disadvantage if you play with a lot of the same people online, but unless someone has 1000s of hands on you, it probably won't be that big of a deal.
If you don't want to play with a HUD, make mental notes of how often players are doing certain actions. It is a lot easier to look at a HUD and see someone almost never 3bets preflops and fold, but it isn't 100% necessary
I like using the HUD to improve my own game. It helps to identify flaws in my play that can be exploited. When reviewing my stats, I can make adjustments that could then transfer over to live play. Without a HUD, I probably wouldn't even know the mistakes I was making in the first place, so it would take much longer to make those adjustments.
For me HUD is useful in a long run. It can not stop you to also monitor the players on the table and not blindly trust on the HUD statistics. If you use HUD just as additional tool giving some more information about players it can not hurt your live game.
