Tournament strategy will vary widely depending upon the game, the ante schedule, and the quality of players that you are up against. If you are playing hold ‘em with an aggressive blind increase, you will need to take chances sooner rather than later because you do not want the blind increases to make you go bust. This might lead to early all in situations in no limit, but this is a chance that you will have to take, especially when you have a good hand. While it is true you might bust out more often at PokerStars.net than if you played passively, if you choose your hands correctly, you will have a bigger stack more often than you will bust.
The quality of the competition will also dictate how you play. If your opponents play many hands aggressively with mediocre cards, it will create good opportunities for you to trap them when you have superior hands. If your opponents play very few hands, you will be able to bluff them out of pots more often when you have marginal cards.
If your opponents are more skilled than you are, you will also need to adjust your play. In these instances, you will need to play only premium hands with an occasional bluff. This strategy works well because when you show your hands, your competitors will see that you play great hands only. This opens the door for bluffing situations. If your bluffs are exposed, this also creates a good situation for you since they will think that you bluff more often than you actually are.
