It's already playing a fairly tough game. I note
that Zeb is using a computer, and someone
called ChessChallenger7 is obviously doing so
as well.

I'll take that as a compliment, but ChessChallenger7 is a mere human,
namely me :-).

The original Chess Challenger 7 was a stand-alone chess computer made
in 1978 by Fidelity Electronics. I inherited one from my uncle in the
early 80's.
It was my intention to have it play a couple of games against GetClub,
but unfortunately - and to my great disappointment - it was no longer
working :-(.
Since I had already made a login for it, I thought I might as well use
it and play a couple of games against GetClub myself.

A while back I did run a few games against GetClub with another
antique chess computer: Par Excellence (built in 1986, also by
Fidelity Electronics).
Par Excellence was leading by something like 8-1. Not bad, considering
it's running on hardware that's more than 500 times slower than the
machine that's running the GetClub applet.
