HUD/database software's primary usefulness, in my opinion, is multitabling (playing more than 4 tables at once). If you're going to do that it's almost required to use PT/HEM, because you just don't have time to pay attention to your opponents. You need stats on them so you can at least, at a glance, get an idea of what their ranges are.
It depends. If your primary goal is to get up to NL50 or NL100 and consistently beat that game while playing 12 or 16 tables and make money, yeah, use and mastery of PT/HEM is pretty crucial. If you're just trying to become the best player you can, though,
you have to pay nitpicky close attention to everything your opponents do. So in that I agree with Fees; it's better for a beginning player to learn to read opponents first, then add PT/HEM to their game.
I'm not saying HUDs are bad or you shouldn't have one. I'm saying too many people rely excessively on them and don't watch their opponents themselves.
The #1 problem I see with hand histories posted here isn't that the posters are too weaktight, or that they're too spewy, or that they want to fold a set on the flop when they should never do that, or that they bet or raise without a clear idea of why. The #1 problem I see is they aren't really paying attention to their opponents. Yes, I know sometimes a hand develops against an unknown player within your first orbit or two. But it seems like most of the uNL posters are getting themselves in tough spots because they just don't know their opponents. And then sometimes we think '38/14/4 over 41 hands' is a read.
I'm TAGgy, but there are times I'll go 200 hands and VPIP 90 of them, because I just pick up that many small pairs or suited connectors, or the table dynamics (lots of limping) are such that I'm encouraged to play all kinds of semitrash like 9
7
. If you raise with K
J
in the cutoff and I call you on the button, and the flop comes J
4
9
, and you c-bet and I raise and you call, and then the turn comes 4
and you check and I bet half the pot, you'll post a hand history and explain how I've been playing 45/22/4 over 200 hands, wow, this guy's an aggrodonk... except surprise! I'm really more like an 18/15/3 player, and though I push hard preflop and on the flop, if I'm still in the hand and betting the turn, It means I was holding 9
9
or A
J
, and you're in trouble.
Yes, there are stats that will tell you how hard I push after the flop action and what it probably means. But it's hard to look up those stats to help you on the fly, while your time bank's running. If you'd been paying attention to me, you'd have an alarm bell going off in your head saying 'this guy's aggro but when he's still pushing late in the hand he's got a strong hand, I better get out of here' as soon as I bet the turn.
OK... it's 5:30 AM and I'm rambling and probably ranting and making no sense
But I really think it's a collective weakness of uNL--and I include myself in this statement--that we don't pay attention to our opponents enough. This is bad, because whereas at 2000NL Villains will be subtle and tricky, at 25NL most of them are caricatures, and the information's there to be had. And please, please, TAKE NOTES! I can't always do it when I'm 4-tabling (4 is the most I do, and more often I stick to 2), but I try to put a note down every time I see a showdown happen at the table (not just the ones I'm involved in).
CLIFF'S NOTES/TL;DR VERSION: A HUD is a poor substitute for notes.
