I love chess matches as much as the next guy but time to turn the page. Both are near end of career and more to offer elsewhere I'd say. I respect both, first two were fun, third was alot of fine countering but alot of waiting around. Familiarity can breed contempt but it can also be quite predictable and ooze 'been there, done that'. Even Balboa and Apollo knew enough to do a finale after hours when the lights went dim in an empty gym.
