AWhen HAL makes his final move he mistakenly says "queen to bishop three" instead of "queen to bishop six." This error foreshadowed HAL's mistake with the AE-35 diagnosis, indicating that something was wrong. This game was based on a game played between Willi Schlage, a tournament player, and a mysterious person named Roesch -- mysterious, because nobody seems to know his first name, and there is some disagreement in what year this game was played. Roesch makes several beginner's mistakes. The fact that an otherwise insignificant game is recorded implies that this was a teaching game. It's certainly not a tournament game as has been suggested. From this information, we know that Poole is a beginner and, perhaps, learned the game on-board the Discovery to pass the time. Although HAL incompletely describes the checkmate setup, he was accurate in declaring victory. In addition to the moves he describes, HAL can also win by playing Nh3. Poole then would be forced to play Qh6 in order to prevent his queen being taken by a pawn. Then, there would be no way Poole could stop HAL. This shouldn't be seen as a mistake, because Kubrick was famous for paring down dialogue in order to speed up the pace of a film. For more information, see here.
