The most foolproof program I've seen yet, allmost bugfree, Mattel is bound to
want to hire you now.
Example of Dann's 286 Chess program output:
[windows]C:\DUMP>chess
Tell me, Kasparov, what move should I make?
d4
I choose: d4
Tell me, Kasparov, what move should I make?
Nf6
I choose: Nf6
Tell me, Kasparov, what move should I make?
c4
I choose: c4
Tell me, Kasparov, what move should I make?
