Poole and HAL play a game of chess. HAL corners him and Poole resigns. Later, Dave sketches the hibernating crew and HAL asks to see the drawings. He tells Bowman that his drawing is quite improved. HAL asks Dave if he's having second thoughts about the mission, while admitting it's had suspicions about the strange stories coming from the moon and all the secrecy during preparations for the mission. Dave doesn't answer; he tells HAL he's probably working on his crew psychology report. Suddenly, HAL reports failure of an antenna control device in 72 hours.
