Chip Dumping - The intentional losing of chips to a friend or partner.
Chip dumping is a type of cheating that occurs most often in tournaments. It happens when a player with a lot of chips intentionally loses them to a friend or partner with relatively few chips. Usually, the dumper has some kind of vested interest in the dumpee. The idea behind chip dumping is that two players with healthy stacks can make more money in the long run than a big stack and a small stack.
Tournament chip dumping is just one of many ways that players who team up can gain an advantage over players who do not. Even if it is only done to help a friend survive in a tournament, it is highly unethical, and in violation of TDA rule #33 regarding ethical play. If caught, both players involved may be disqualified from the tournament. However, it is very difficult to prove chip dumping, because the dumper is usually mucking his hand unexposed before the showdown.
Chip dumping occurs in a different way when playing
online poker, but it is rare. Sometimes online players dump chips when they are trying to avoid being caught doing something else. An example of this is credit card fraud: A player steals a credit card, makes a deposit on one account, then intentionally loses (dumps chips) to their real account.
Collusion - A cheating conspiracy between two or more players.
When two or more people engage in coordinated cheating in a
poker game, it is called collusion. Collusion takes many forms, and it runs the gamut from relatively benign to malignant. For example, a milder form of collusion occurs when two players agree to “check it down.” This means that both players agree that neither will place any bets for the remainder of the hand, and at the end of the hand they will simply turn their
hands up to see who wins. Sounds harmless, right? Actually, this is a form of collusion and is technically considered cheating. Here is why.
Consider a situation where player “A” and player “B” are friends, and they have a standing agreement to check it down whenever they are heads up. This agreement can affect the way the action transpires to the detriment of the other players in the game. For example, imagine that player “A” and player “B” take a flop with a third player, player “C.” If player “A” bets, player “B” knows that if player “C” mucks his hand, player “A” will subsequently check for the remainder of the hand. This provides an incentive for player “B” to raise, even with a lousy hand, in order to eliminate player “C.” So you can see that the latent agreement between players “A” and “B” can harm player “C.” This is a textbook example of collusion. Even if the collusion is so mild that it has no discernable impact on the game, it is harmful because it puts the integrity of the game in question, which in itself has a negative impact. Additionally, there may be consequences to collusion that are hidden or not immediately apparent.
More malignant types of collusion include the formation of “teams.” These teams consist of two or more players who act in the interest of the team as a whole rather than in a self-interested manner. Often, these teams will use secret signals to covertly communicate and coordinate their actions with other team members. They will share information such as betting instructions, and hand content. The damage that this type of collusion can cause is more obvious that of milder forms. In between these extremes, collusion can take many forms, but they all have one thing in common: players cooperating when it is not allowed. This is why the rule which states “one player to a hand” is a constant in the poker world.
A partner in cheating is called an "agent". It is difficult to cheat by yourself in a poker game, because it must involve manipulating cards or chips. It is much easier for two or more people to cheat, because they now have a third option of manipulating the action. This type of cheating is easier to pull off, and harder to detect, because one or more of the cheaters is usually betting or raising, and then mucking their hand unseen. This creates an incentive for cheaters to form a team. Anyone on the team of a cheater, actively helping him to cheat, is called an agent.
An agent is usually another player in the game, but could also be a mechanic (a dealer skilled at manipulating the deck), or a floorman (by way of an intentionally incorrect ruling). Most commonly, a cheater will covertly signal the agent that he has strong hand. The agent will bet to generate action from the other players. The cheater will reraise the agent, building the team a large pot. The agent will be sure to muck his hand before the showdown. Since the content of the agent’s hand is not exposed, it is very difficult to determine that cheating has occurred simply because one player raised the pot and then subsequently mucked his hand.
Soft Play - Soft playing occurs when a player strongly suspects that they have the best hand, but does not bet because they are up against a friend. This is also illegal, but the consequences are often less severe than those for chip dumping.
