Corrected entry: In the second to last scene of the movie where Mike is playing heads-up with Teddy KGB, there is an inconsistency in the bets that are made. Previously in the movie, the black chips are shown to be worth $100 each. When Mike raises $1000 straight, he places 20 chips down, a total of $2000.
Corrected entry: In the final showdown with Mike & KGB, Mike goes to the poker showdown with $10,000. In the first game, he beats KGB in a winner take all and doubles up. If that is the case, Mike would now have $20,000. Mike gets ready to leave, but KGB goads him into playing another game for double or nothing. Mike again beats KGB to double up to $40,000. However, Mike states his winnings to be $60,000 with the breakdown of his winnings as follows: $15,000 back to KGB and Gramma, $10,000 back to the law professor and $6,000 back to the Chesterfield. This totals $31,000 which would leave only $9,000 left. Where did the other $20,000 come from? This amount is never accounted for in the movie in the final showdown with KGB.
Corrected entry: During the Judge's game, when Mike calls out everyone's hand after the flop, Judge Gene Mariucci seems to scoff and drop three cards from his hand, on to the table. If they are playing Hold 'Em; Gene and the rest of the players would only be holding two cards in their hands.
Corrected entry: When Mike is playing KGB at the end of the movie, in the last hand of the first game they play when Mike wins with Jacks Up, Mike is the dealer. However when Mike reaches out to rake the chips in, the deck of cards is sitting in front of KGB, to the right of where his chips were.
Corrected entry: In the final card hand between Teddy KGB and Mike, Teddy lays down an ace and goes "all in," commenting menacingly to Mike that "Your fate is sitting right beside you," implying that loan shark Grama is waiting to break a few bones once Mike cannot pay off the debt he inherited from Worm. But if you look at the table, Mike has at least three times the number of chips that Teddy has, even more than when Mike won the $10,000 from Teddy earlier. Mike does not have to go "all in" (which he does), but merely call the bet. Even if he were to lose that hand, he would still have more chips than Teddy, enough to pay Grama off. You would think Teddy would know that, since the chips are right there on the table. His comment that Mike will not be able to pay Grama doesn't make any sense, although it does heighten the drama.
Corrected entry: When KGB and Mike are playing heads up in the end of the film and Mike is dealing the cards he first deals the "turn card" i.e. the fourth community card and then deals the "river", fifth community card, without discarding one card. In Texas Hold 'em you always take the top card away when dealing the community cards because cards can be marked and by doing so no-one will know which cards are coming even if some of them are marked.
Corrected entry: When Mike is playing KGB for the second time, right before he throws his Oreos they are almost gone but in the next shot it is almost a half full again.
Corrected entry: During the part where Matt (Mike) is on the bed he tosses his hat on it, but in the next shot the hat is gone.
Corrected entry: After Mike is taken for every penny, Judge Petrovisky writes him a personal check for $10,000, which he then takes to a check cashier. These businesses take between 2.5 to 5 percent for cashing a personal check, yet he is able to show up at KGB's club with the full ten thousand.
Corrected entry: There are several instances of improper poker playing in this movie. 1. When KGB is going to bet 15,000 into Mike early on, he puts one stack of chips out, then reaches for more and announces his bet. This is called a string bet, going back for more without FIRST announcing how much you are putting in. KGB's bet should have only been his first stack. 2. In one of the home games while Mike is trying to win back money, a man says, "I call your 1,500, and bet all-in" or something. He should have said, "I see your 1,500..." By saying "call" he is calling, and therefore can't put any more money in the pot. 3. There are several players who "splash the pot." Putting chips right into the middle, instead of a little in front of you until the betting round is over.
