I think the best variant is to have no strategy. I'll explain.It's obviously: if you have a strategy someone can read it. No strategy - "no problems". But don't hurry up! I don't encourage mindless game. I just say: don't pin to one strategy. Your game should be flexible: your opponent is aggressive? Use slow play. Is tight? You can steal a pot. Don't be fixed: "I am playing tightly, today I won't do bluff. Also, you see your position - so choose right game style for it. That's main thing to keep in mind.
I get what you're saying, but if you're always switching around from tight to loose depending upon table dynamics, how are your opponents going to view you?
It's likely they'll just think your a loose player. If they see you play tight and see you play loose, it's the same thing as just playing loose because loose players open with strong and weak cards.
One thing all players need to stop doing is acting static about their pre-flop decisions. It's not just a matter of being in X position with XX cards so I'm supposed to open or raise. These types of "Book moves" aren't always profitable moves even when we have good cards. We need to ask ourselves some questions?
If I open, how likely am I to win?
Will any of the guys in front or behind call?
If they do call, how many will call?
And what if they do call? How hard or easy will it be for me to win the pot?
Will I be able to bet the flop and make them fold?
Do I even want to c-bet this hand?
How often are they folding?
Will a check raise work?
How often are they check raising?
Am I going to get 3 bet?
Who's going to 3-bet me?
How often are they 3-betting?
If I do get 3-bet, do I want to 4-bet with this hand?
Do I want to jam all-in with this hand?
People aren't asking themselves these questions. They just statically open or 3-bet without thinking ahead. We want to put ourselves in profitable spots. The answers to questions like this will help us figure out if we have a legit shot at winning. If you don't think it's going to be profitable, don't play.
