Computers are usually thought of being logical, unemotional, not given to either having or displaying emotions. This is the pervading opinion of the general public. That is, unless you’ve watched 2001, A Space Odyssey.
But do computers have emotions? Do they feel joy when they win? Do they fear an opponent? How about a simple move?
Lets’ take a look at the following game:
DEEP FRITZ 8 (2462)-SQUASH 1 v. 1.35 (1962)
Computer game, 2005
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.Bc4 d5?!
[In this variation of the Scheveningen, Black has a number of responses, some good, and some that should be avoided. The text is considered borderline and is rarely seen. Here is another response, equally borderline.
Oliver (1925)-Rios Cidras
San Sebastian Open, Apr. 3 2007

21…Qxc2+!? (You might reasonably conclude that SQUASH either panicked or made an incredibly insane blunder. But computers, by definition, cannot be insane, nor can they panic. Here is what SQUASH probably saw: 21…Ne6 22.Qg4+ Ng5 23.Qxc8#. And 21…Qe6 loses to 22.Qe6+! Qxe6 23.Re8#. With the queen sacrifice, Black lives a move longer. See, the computer is not so insane after all!) 22.Kxc2 Ne6 23.Qg4+ Ng5 24.Qc8mate 1-0
