Recently, while occupying our VAX 11/750 with a brisk game of
BSD 4.2 chess, the following sequence transpired...
17. k/qb1-qn1 I got out of an irritating check
... b/qr6-qn5 He decided to pin down my knight
18. r/kr1xp/kr7 I placed some tempting bate out
... k/kn1xr/kr2 He couldn't resist! See comment below
19. r/q1-kr1+ First stage of the trap closes
... k/kr2-kn1 His only move. This took only seconds.
8 R * - Q R * K * \\
7 * P P - * P * - \\
6 - * N * P P - * \\
5 P - * - * - * - \\ After
4 - B b p - * p * // #19
3 * p n - * p * - //
2 - * - q - p - * //
1 * k * - * - * r //
q q q q k k k k
r n b b n r
20. q/q2-kr6 Close the trap! One move to mate.
... q/q1-q4 No hope in sight for mighty-machine,
--> However, this desperate move took
him OVER AN HOUR to complete.
21. q/kr6-kr8+ Gotcha!
Resign Seems like he ought to say more.
I am posting this to contact anyone who might have encountered similar
response from the chess in BSD 4.2; especially someone who might fix it!
I know it must be embarrassing for the bits to loose, but to use
over an hour of time to realize that the mate was inevitable is just
poor etiquet; both I and the CPU were abused. If the author is out
there, you might use this case to expedite a loosing situation.
Also, this game's end is a hint to those who would tangle with this
particular chess program. He is very long sighted for balanced attacks
but this intelligence is lost when lopsided trades are offered.

Quite sincerely, ...still waiting for the electrician,
Dennis Kodimer or someone like him.
