A player who plays extremely tight is called Rock. Tight play is not the best decision since very soon you will be very easy to read and the other players will not answer your bets. The Rock is an extreme and you should play this style only if there are a lot of other extremes at the table such as maniacs. If he gets callers when he opens the game, chances are he will take down the pot. The Rock plays a few hands and places value only on the strongest pairs. From time to time he can play smaller plays but he is not going to raise with them. The Rock can make profit only if other players do not pay attention that he plays too few hands of the hands he is dealt.
