You dont always know how a poker player will react to what has happened to them at the table.  Take a time out when the below circumstances take place to determine how the table has been affected:

1. A player just won a big pot
2. A player just lost a big pot
3. A player at the table just got caught bluffing
4. A player was just eliminated
5. A player is tilting
6. A player has likely changed gears
7. The blinds have been increased

In online poker, its much easier to do this than it is in a live poker game, but you should definitely think this way in both circumstances.  Once you have chips in your hand, no longer view the chips as money.  They are just chips.  Clay chips that you can use as your force.  If you remove the idea of cash behind the chips – you will be able to focus more on playing the game then on winning money and then you will find yourself winning more money than you thought possible!

In my honest opinion, you are much better off using slow playing tactics in a tournament than in a cash game.  The reason being this:

In a cash game, slow playing easily gets you into trouble, and you are risking a lot more money in these circumstances.  The long term gains of a cash game are relevant based on what happens over the next year, not necessarily what happens in a few sessions.  Bet all your strong hands strong, and you will get paid off in the long run.

In a tournament, your money is already invested.  Chips are generally managed more strictly and therefore; you have to take the best opportunities to build your stack gradually without risk.

Keep in mind my previous post however (Flopping a Monster).
