Poole versus HAL 9000
Poole versus HAL 9000 is a fictional chess game in the movie 2001: A Space Odyssey. In the movie, the astronaut Frank Poole is seen playing chess with the HAL 9000 supercomputer. As HAL is supposed to be infallible, no one is surprised when HAL soundly defeats Poole (though the novel mentions that HAL is programmed to win only 50% of the time in order for there to be some point in the astronauts ever playing).
The director Stanley Kubrick was a passionate chess player, so unlike many chess scenes shown in other films, the position and analysis make sense. The actual game seems to come from the tournament game between A. Roesch and W. Schlage, Hamburg 1910.

- The opening is the Ruy Lopez, Worrall Attack.

- This move deflects the queen, allowing Black to mount a kingside attack. Instead, Matanović recommends 12.d4 leading to a small plus for White after 12...Bb7 13.Qxf4 (13.Qxb7 Ne2+ 14.Kh1 Nxc1 15.Rxc1 Nd3 16.Rf1 c5 gives Black compensation) 13...Nd3 14.Qf5 Nxc1 15.Rxc1 g6 16.Qg4 Bg5 17.Rd1.
- Threatening 13...Ne2+ 14.Kh1 Ng3+ with checkmate to follow.
13. Bd1 Bh3!
- Black also has 13...Bg4, winning a piece after 14.Qb7 Bxd1 15.Rxd1 Ne2+ 16.Kh1 Ng4 17.Qf3 Qxf3 18.gxf3 Nxf2+; or 13...Nh3+, winning the queen after 14.gxh3 Bxh3 with the dual threat of Qxf1# and Rxa8. The movie picks up the game here (see diagram).
- White abandons the long diagonal and moves into a forced checkmate. Even after 14.Qb7 c6 15.Qxe7 Bxg2 16.Re1 Nf3+ 17.Bxf3 Qxf3, mate is not far off.
14... Bxg2 15. Re1 Qf3
- Here HAL says: "I'm sorry Frank, I think you missed it: queen to bishop three, bishop takes queen, knight takes bishop, mate." But HAL's description of the queen move is not technically accurate—the move is correctly described in the descriptive chess notation as "queen to bishop six". There is some conjecture that this inaccuracy is a subtle foreshadowing of either HAL's breakdown or of his deception of the crew.
- Poole resigns without questioning HAL's analysis.
