Nah, KNVB and CapilanoBridge played on ICC.
My theory on KNVB

KNVB account on ICC was not active at the time though.
"Information about KNVB (Last disconnected Wed Aug 05 2009 01:09)"
However is this the same player as the KNVB on here?
Who knows, it could have been anyone, including Nakamura. From what I have seen though, its just a strong club player who is very quick.
I noticed that Hikaru Nakamura's ICC account is CapilanoBridge, but the flag is of the Netherlands.
I also noticed that the ICC account CapilanoBridge became active playing bullet games at the same time as KNVB was banned.
Is this just a coincidence?
