I wonder if this is the level of interest of this poster? I say he can't
write his name to his comments, and he doesn't understand it - he agrees,
but choses to divert as if what I wrote indicated a misspelling, rather than
cowardice.

It never occured to me this is how it is meant for the obvious reason
that it is standard practice on usenet--for a variety of reasons--it is
extremely common to use monikers on the internet, so the accusation of
me "not writing my name" makes no sense.

Yes it is. You are as unable to understand compound sentences in English as
complex variations in chess.

I admit that when Mr. Keene writes the variations, or when you write
the compound sentence, I have extreme difficulty understanding it.
Strangely, though, this doesn't seem to occur nearly as often when
others are the authors of the chess or the English.
