Hand in Texas Hold'em, a six-two off-suit, named "The Sweeney". This has a propensity for flopping 2 pair and turning a boat. It's broken pocket aces and pocket kings in the same night. It should only be played by those with faith in the Sweeney, or if it comes as any Sweeney walks in the room. Never try to turn it against a Sweeney as it will only end up hurting you.
What kind of idiot would call $20 with a 6-2? I'm golden with my pocket aces.
