I wanted to say this for a long time but i am kinda polite guy myself. You do not need to tighten up or to loosen. You need to learn poker mate.
The goal of this game is to eliminate the luck factor as much as possible.
"Small hands, small pots, big hands, big pots" . This is what poker is about. You have to make it si that when you have marginal hands to control the size of the pot and when you have strong hands to put money in. I do not understand why most players do exactely the opposite. They bluff with garbage making the pot big , and they w8 for the opponent to put the money in the middle when they have a monster.
We all do get suckouts. It is unavoidable. But the suckouts are not the element that take us down. Playing big pots with marginal hands or bluffing with air are the stupid things we do so we get broke.
Here are 2 examples of stupid things that beginners do again and again.
I mean. We raise 3BB from MP with 66. We get reraised and we call against the odds
so that we setmine. The flop is 743. Villan raises 3/4 of the pot and we call because we think he is bluffing. An A comes on the turn. Villan checks and we go all in because we thinnk he will fold because he showed weakeness. He calls and he has set of aces.
Or again . We raise from MP with 66 against a loose passive guy and the board is 87J with 87 of the same collor. We c-bet he calls. Turn is a dewce. We c-bet again he calls and the river is a 5. We c-bet he calls and he shows 67.
So after doing this kind of bad play again and again loosing like 5-6 buy-ins we get Aces . We raise , we get reraised and we shove. Villan has 44 and he gets a 4 on the flop. We loose a buy-in. We quickly go at the forum and scream like there is no tomorrow that poker is rigged. Our game is good we play like gods but somehow we get busted.
Sorry for derailing. But i had to say it. You are a losing player because you play bad overall. My advice is to start with the basics.
PS. This was not only for you. This is for all the players that leak money ans than ask why. Sometime a brutal approach make the one that listens to really listen.
