As the game progresses, every player will have more information about the style and behavior of his opponents.
It will always be wise to take this information into consideration.
There are players who go all in whenever they have a good hand and there are those who will immediately fold when given a weak hand.
When a player takes too long to act, it is probable that he lacks confidence in his hand.
This could be a good time to bluff. Of course, there are players who are very hard to read as they have mastered these strategies as well.
But, no matter what, paying attention is a must.
Observing the dead cards, the actions of each player, and patterns of behavior can lead to a very successful run at the poker table.
