While each poker player has their own unique playing and decision making style, there are basically only four main categories of players. Belonging to this or that type players have both strong and weak points and all of them have advantages over others in some particular situations.
There are at least two main attributes for each of these types.
Depending on the number of hands the player plays with the players can be either tight or loose. Tight players play few hands and loose players play with a lot of hands.
If the player is aggressive (raises and bluffs) or passive (calls other players bets).
Loose-Aggressive
Loose-aggressive player is the weakest player especially in online poker game. The main feature of such a player is that he raises every time after the flop. In a real casino such a strategy will allow to win only small pots, but in online casinos they will be only a flop. Sharks are often attracted by such players. The sharks are fine with letting these players have 10 small pots; they are after the three large pots which will eventually break this player. To avoid such results it is better for such players to change tables from time to time. For example, every 50 hands.
Loose-Passive
They are no more stronger than the first group. These players can only make money in a game with a lot of wild players and generally have to depend on luck to have a successful poker session. Their strategy is to call the bets of other players no matter how strong their hands are. Such players can stay in the game longer than anybody else, but they will never be able to beat the house edge.
Tight-Passive
What allows players of this type to win is other players who play the game wrong. Such players are easy to notice. You never have to worry about a bluff from them. If this type of player has a decent hand or a lot of outs, he or she will call your bet or make a small bet. If not, they will fold.
Tight-Aggressive
This is the best type among all others. They have the following principle of the game: see a flop with a decent hand and then take a shot at the pot after the flop with a bet. Standard American Poker Win.
