To consistently win at online poker you must minimize your mistakes,
and
exploit your opponents errors and weaknesses.
Here is a list of rules to follow to play online poker more profitably
Learn the math behind poker - Learn about odds and probabilities and how to
use them in poker. This will give you an advantage and make profitable
decisions. Read about Odds and Probabilities and look at the Odds Chart
Learn about table position - Learn about early, middle, and late positions
at the poker table. You should play very few hands from early position and more
hands from late position because you are more apt to bet last in late position
Don't play a lot of hands - You should roughly be playing 20%-25% of your
hands depending on the type of table you are playing. Check out the starting
hands guide
Find a loose table with weak players - Find a table with a high percentage
of players seeing the flop and staying in hands on draws
Find calling stations - Find people who will keep calling all the way to the
river to a showdown. These are players that make many mistakes
Stop playing if the table dynamics change - It's easy to change tables or
stop playing online. If the table dynamics change (different players, less/more
players) to something you are not comfortable playing then stop playing or find
a new table
