Subject: What was Chess Challenger 7 thinking?

I dusted off my old Chess Challenger 7 last night and played a game.  Granted it
was set at level 1, but I can't figure out why it would play 14...Qb6.  All it
had to do was move its queen to d7 or e8.  Wouldn't even a 1978 computer do a
full 4 ply search?  Did the CC7 use selective searching at the root?
