Even though I could not read everything, i kind of understand the point you are trying to make.
Your tips on bluffing right in a poker game sounds reasonable.
I have seen people bluff during card games but I never knew it was a poker strategy
Though bluffing is very useful in every kind of game it's not just in poker and as far as i remember they call it as self-deception.
Allowing yourself to believe a lie that looks real to the other people and that's how you do the bluffing strategy.
Using this kind of strategy in the same people everyday will not gonna work anymore unless you do randomly or not using the same technique in front of people who do know your strategy very well.
There is no myth to win poker . Yes , if you are an experienced player you can use your skills to perform better in player to player match. But again you need luck in poker too to get better cards than your opponent.
I do find poker to be more interesting only because of involvement of some skills while playing.
