Even though he has withdrawn from competitive chess as far as I know, Korchnoi is still in good enough shape to play exhibition matches. He won two games against Uhlmann in Leipzig this weekend. (Uhlmann is only 6 years younger, but still played in the Bundesliga two years ago and in Snowdrops vs Old Hands last year.) Here are the games with annotations in German.
Thank you for passing that along, and for others' convenience I've posted the games here for reply and download.
