The guy who made the bongcloud opening
Who is the worst chess player ever?

We all have heard of the chess greats. Fischer, Kasparov, Carlsen, etc. But who is the worst, I mean the WORST rated player there is?
Here is my criteria:
I am not looking for a strong master who has had some off days (e.g. Nigel Short)
The person must be playing for a substantial amount of time.
The person is at least 10 years of age.
I have a few candidates:
Ruth S Arluck
Noreen Davisson
Ken Cohen
I am sure that these are all great people to be with, etc, but perhaps chess is not for them.
Okay this one is 5 years old. But still... mentioning Nigel Short in such a thread??? Really??? He played for the world championship.
