You can use all the advices given so far, but not against all of your opponents. As you study the game, you will learn how to determine the style of your opponents and to adjust to their own game. If a player is afraid of big bets of the opponents, use them as semi-bluff. The three-level semi-bluff works well against a thinking opponent, because with each of your bets, the value of your hand in his eyes will only grow. However, there is a group of players against whom such deep bluffs just do not work. These are people who find it extremely difficult to lose a hand, after they put some money into the pot. They are usually called “emotional” players, because they have very strong almost family bonds with the pot and to break them is virtually impossible.
