You're quite a "brown-noser" aren't you?

And you told me Authority didn't carry weight with you!?

I think Robin made his point and I wouldn't put as much stock in games such as
these as there is no impetus for the IMs/GMs to win, other than pride. The T/C
are very important too, so I hope you selected 120 standard.

Another thing, people are often put off of seeing openings listed as A00 down
through the list.

Oh sorry, you know soooo much more than I or Robin or just about anyone you
disagree with.

We have names for people like you but it would get me banned and that would make
you so terribly happy, so I won't accommodate you.
