There's a strong invitational blitz (3' + 2") tournament this Saturday in Oslo, Norway, starring Magnus Carlsen and Hikaru Nakamura. It should be a lot of fun, but I am slightly worried that if Nakamura is going to go from America to Norway to America to London (for the real tournament there starting December 7) he may not be 100% when it really matters. That's for him to worry about; for us, we get an extra little show.
