If you want a advantage check this site out
http://www.poker-edge.com it was made by a few college students who run several servers that request the hand histories for every single hand played 24/7 on the party poker "network". Using this information you get a great deal of info on the player such as how ofter they see the flop, agression, what type of cards they play, how they act on the flop/turn/river call/fold/raise , what tables they play at 1/2 5/10 NL etc.. Its $20 a mth to see the higher limits but seriously i made that back in 1 hand using the information. The main feature is that it shows whos a fish(loose) and whos shark(tight) find a table with 4-6 fish and 1-2 shark, once u play a hand look whos in the pot and make your moves. One of the things i love is when you arent in a pot and ur watching a fish heads up with someone and you know exactly what hes gonna do and what cards he has. You can even see your own stats to see what ya doing wrong/right.
End of rant.
