All you need is 1 player to increase your winning % by at LEAST 20%. For instance, the 2 of you can force other players to fold on almost EVERY single hand. Here is something to look for to determine if it is happening to you. At bigbetpoker, I caught at least 5-8 people doing this sort of shit!
Lets say that we have a game with about 5 people. By the way, the fewer players, the better for this sort of help! Well I noticed that 2 players almost ALWAYS stayed in on the same hand! Then when they would force someone to fold, the hand WOULD NEVER go to the last card or at least one player WOULD always fold so they didnt have to show the bluff hand or better yet then they wouldnt have to show either hand!
Watch closely for people who are raising the hell out of the game and then ALL OF A SUDDEN, one guy doesnt call a small bet! They bet this way for 2 reasons. First is the most important reason, not to dislcose that one or both didnt have shit in the hole! The second reason is to not lose anymore money in the rake.
Also keep in mind that some players are COMP players where they get a % of the rake and get paid to keep people at the table!!
