Patience is the key. I know, because I often do not have it. It is hard when hand after hand is bad cards. It is a killer when you fold 27 or 38 and the flop would have given you a full house. It makes you want to just call and see the flop. It can work at the beginning of the tournament when the blinds are lower, but the farther into the tournament, the bigger the risk as you will just bleed most times. Even with and A2, if you pair the ace, someone will most likely out kick you. If it is suited you have some flush possibilities, but high pair Aces can be a dangerous hand, with a low kicker.
I often wonder if I am being bluffed out of a hand. It is always better to wonder, then call and find out he wasn't. It is easy to think of look how much I will gain if I win this, when you should often look at how much you will lose if you lose.
A well placed
bluff will work, but there is always the risk that it won't. A bad bluff tends to not work unless they really do have nothing.
I always have to fight the urge to play every hand. I want to see how it goes. I want to be in it. The better I become at picking which hands to play, the farther I go.
I had one tournament where I was in the bottom until I was in the money. Then I started hitting good hands and move up to the top. Fortunately, my hands were either really good, or really bad. Than can help you go far.
