These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Awesome: "You're right, Teddy, that ace didn't help me. I flopped the nut straight."note The "nut" being the best possible hand with that particular flop. He had won the hand before the river was ever revealed, but bluffed an already rattled Teddy into betting it all.
Fanon: It's never shown what Teddy KGB was holding in the final hand of the film. However, among fans of the film it's generally agreed upon that he was holding pocket Aces, as evidenced by:
He beats Mike at the beginning of the film with the same hand (the Ace of Hearts and the Ace of Diamonds)
His remark when the river card is the Ace of Spades ("That Ace could not have helped you.")
He taunts Mike when the Ace shows up on the river ("It hurts, doesn't it?"), likely believing himself to have the best hand with a set of Aces versus a probable busted draw from Mike.
His decision to go all-in on the river.
His breakdown when he loses the hand.
Earlier in the film he slow-played his pocket Aces, when his Aces full beat Mike's nines full. Teddy was likely trying to slow play his pocket Aces again.
The DVD features a commentary track from four real-life pro poker players. They also believe that Teddy was holding pocket aces.
Fan-Preferred Couple: A lot of people who have seen this movie don't understand why Mike rejected Petra's advances, due to the fact that she seems to be a much better match for him than Jo was.
Narm Charm: John Malkovich's over-the-top portrayal of Teddy KGB is widely considered to be one of the most entertaining things about the movie.
Retroactive Recognition: The film was released before major poker players became television personalities, so the cameos and named references will nowadays be already familiar to many viewers.
