Collusion is when two or more players secretly work together to gain an unfair advantage at the poker table. It’s poker’s most serious form of cheating, the equivalent of bringing a team to a duel. Unlike angle shooting or poor etiquette, collusion is outright theft from other players.
Collusion takes many forms in poker, from the subtle to the blatant. Partners might share hole card information through signals or messaging apps, allowing them to make perfect decisions against unsuspecting opponents. They might squeeze other players out of pots through coordinated betting, or soft-play each other to preserve their stacks. In tournaments, colluders might dump chips to one player to give them a better chance at the final table. Online, collusion can involve sharing screens during play or using multiple accounts controlled by the same group.
The damage from collusion extends beyond individual victims. It destroys the fundamental assumption that makes poker possible, that each player acts independently in their own interest. When this trust breaks down, games die. Regular players leave, new players get discouraged, and eventually only the cheaters remain at empty tables. This is why reputable poker rooms treat collusion as their highest enforcement priority, employing sophisticated detection systems and imposing lifetime bans on violators.
How to Spot Collusion
Recognizing collusion requires attention to patterns rather than single incidents. The most obvious red flag is soft-playing between specific players who show aggression against everyone else. Watch for players who consistently check down big pots against each other while betting aggressively in other spots. In a recent high-stakes game, two players checked down three streets with top pair versus a flush draw, a dead giveaway when they’d been three-betting light against the table all night.
Betting patterns tell the story. Colluders often “squeeze” third players out of pots through coordinated aggression. One player bets, you call, their partner raises, the original bettor re-raises, suddenly you’re facing massive pressure with a medium-strength hand. After you fold, they might check it down or one might fold quickly. This whipsaw technique is especially common in cash games where chip preservation matters less than pot accumulation.
Timing tells emerge in online play. Colluders discussing hands through messaging apps often tank for similar amounts of time on routine decisions. You’ll notice both players taking 15-20 seconds for simple folds or checks, they’re conferring. Live collusion shows different timing patterns: quick folds in spots where any reasonable player would consider their options, or synchronized actions like both players suddenly leaving the table together.
Chip movement reveals the most blatant collusion. In tournaments, watch for players who dump chips through bizarre plays, calling huge all-ins with garbage hands, or making massive bluffs into the nuts. The “losing” player often leaves immediately after busting, while their partner now has a commanding stack. Online poker sites track these patterns closely, flagging accounts that consistently transfer chips to the same players through suspicious hands.
How to Deal with Suspected Collusion
Document everything when you suspect collusion. Write down specific hand numbers, times, and player names. Screenshot suspicious hands online or use your phone to record betting action live (where permitted). The more evidence you compile, the stronger your case. Don’t confront suspected colluders directly, they’ll adjust their tactics or target you specifically. Instead, report to floor staff or site security with your documentation.
Adjust your strategy to minimize exposure against suspected teams. Avoid marginal spots where you might get squeezed. Tighten your opening ranges when potential colluders are in the blinds together. In tournaments, consider changing tables if possible. Online, use the site’s table selection features to avoid games with suspicious player combinations. Your goal isn’t to beat the colluders, it’s to protect yourself while authorities investigate.
Choose your games carefully to avoid collusion hotspots. Private games without professional dealers or oversight carry the highest risk. Unregulated online sites with minimal security measures attract cheating teams. Stick to reputable establishments with active floor staff, security cameras, and clear policies against collusion. Major online sites employ entire departments dedicated to detecting and preventing collusion through statistical analysis and player reports.
Pro Tip: The best collusion defense is game selection. Well-run poker rooms make collusion extremely risky for cheaters. A room that takes your concerns seriously, investigates thoroughly, and bans proven colluders protects everyone’s bankroll. If management dismisses your concerns or seems uninterested in investigating, find a new place to play.
Collusion vs Implicit Collusion
True collusion involves explicit communication and coordination between players. Implicit collusion, also called “soft collusion”, happens without direct communication but violates the spirit of independent play. Examples include checking down when a third player is all-in in a tournament, or avoiding confrontation with certain players due to backing arrangements. While implicit collusion occupies a gray area, explicit collusion is black-and-white cheating.
The difference matters for enforcement:
- Explicit collusion: Lifetime bans, legal prosecution possible, funds confiscated
- Implicit collusion: Warnings, temporary suspensions, case-by-case rulings
- Gray areas: Stable swaps, backing arrangements, last-longer bets

“I’m switching tables. The seat 3 and seat 7 team already squeezed me out of two pots today.”
Key Takeaway
Collusion is poker’s cancer, it kills games by destroying the trust that makes poker possible. Learn to spot the signs: soft-playing between specific players, coordinated squeezing, suspicious chip dumping, and timing tells. When you suspect collusion, document everything and report to authorities rather than confronting cheaters directly. Most importantly, choose your games wisely, reputable rooms with strong security make collusion too risky for cheaters to attempt.
