I would just like to add a few things to the types of poker players. First of all it is not that easy to divide players in to the four groups. I have to agree that a fish is basically just a bad player, which often plays way to many hands.

But whene it comes to tight and agressive players they might not be as easy to beat as the article makes it sound. If i tight player knows his image at the table he has no problem bluffing wining pots by bluffing, with nothing, since anyone belives he only bets when he`s got the nuts. And agressive players can aslo be real good if they ar not plain stupid. Small ball poker has become a well known style of playing poker, and many of the best MMT players use it. By making a lot of bets they get great implied odds to the times they realy make a hand, and if their bets are at the right time they also win a lot of small pots by betting the other players out.

At Last the shark: The characteristics of a shark is that i is in full controll of all the other types of players, and knows which type each player at the table is. And he is able to take advantage of it. He plays farily tight but is not afraid to put his money in when he knows he is ahead. Nough said, A Shark is a winning player!
