Number one mistake nlhe players make
In my opinion, 99% of all errors I see are created because players are passive and don't bet to get information or to protect their hand.
Or for any reason really: Players just don't bet frequently enough. They only bet when they assume they're value betting or they bet when they have the nuts.
They also bet when they have a monster they wish to protect but their minimal hands that are good often go ignored. These hands are sometimes a huge factor in gaining more big blinds and also add to a tricky image of which players will have difficulty adapting to.
I'd think even the aggressive players can be passive mostly, because as soon as they hit their hands, they'd wish the pot to end with that action.
Here's and example
Your hand in the BB
10d6s
Folded to the aggressive SB
SB min raises
Now... you have a pretty cruddy hand, but I think most of everyone agrees that a call here is probably the best course of action.
Flop:
10h 4h 7c
Okay, now we get to look at the problems with this board and discover a few things.
First of all, because we called preflop and the villain has a huge range that he min raises with... we know nothing. He could have AA or 27os.
If the villain bets, I think the most appropriate action is a raise. If he checks you have to bet and forget most appropriate.
I think you HAVE to raise there. For a bunch of reasons. I'll list some.
1. You need to find out what kind of hand your opponent has.
2. Calling shows weakness and could induce another bluff but you have no idea if it's a bluff or it's the nuts.
3. Calling allows him to draw with the appearance of having a hand already, so when the draw comes you won't know what to put him on.
4. Your opponent probably doesn't want draws to come either if he has one pair or better.
5. The raise will take down the pot a lot of the time here and that's a positive.
6. All kinds of draws that you don't even think about like king high ace high two pair draw, set draw(maybe not set draw with that flop) all kinds will be forced to exit the hand (at least they should). These draws can easily overtake your current hand and you'll have no idea that they did.
7. If you fold here, you better have a good reason (like he decided to do a 2x pot raise on the flop before you face or you'd like to setup a hand later or you are playing with scared money.
There's pretty much 7 reasons why you need to bet your medium-strong hand. There's an amazing amount of hands I watch where I have no idea where either player is at because neither wants to make a feeler bet and give up any information.
My opinion is you can't be so scared, because you can always make a move on a bigger pot later if you think it through.
I think it stems back to insecurity and unawareness. The T6 wants the hand to just end. They want to just see a showdown and ship it to whoever has the best hand (likely them). The problem with that is you're not extracting from the draws or weaker hands and you're losing a big chunk of the time to random garbage that catches up and value bets you. You have a decently strong hand that can easily get smoked. Try to remember that showdown doesn't happen on the flop, it happens on the river. The only way to get there without losing your bankroll is by planning ahead.
Tell me if you guys think that makes any sense? It does to me but I don't know.
