I used to think the same way until I realized that the RNG (Random number generator) uses the milliseconds of the clock in its calculation in determining what the next card will be. In other words its not like a deck of cards in a live game where no matter how much time you and the other players take to make decisions the cards remain the same, but with the RNG the cards most likely would of been different if you had stayed in the hand.
Is this true? I have had a quick look through Poker Stars information, and can't find any reference relating to the above.
Basically what I am wondering is, whether after you fold your hand you keep looking at it and seeing how it would play out if you didn't fold it.
Do you get all angry thinking "oh come on I would have totally won that if I didn't fold wht the hell!" or do you accept the fact that folding was the right choice in said situation because even though you WOULD have won if you did not fold, your hand was not good enough pre-flop to keep playing.
Does looking at the hands that could have been won affect you in any way? Do you become careless and start going in with even crappy hands?
