definitly some good bits of wisdom there! a wise man (me) once said, after playing agressive for years I have finally become a tighter player, and if there is one thing i learned...its certainly easier to win the hand when you have the best cards.
Isnt that the point of the game? The people who bluff all the time are the ones who havent played long enough to realize that people figure you out. You should only bluff when you are sure that the other person is weak and will fold.
