"Chess is a good way to learn, to keep your brain fit and the ego in check, a mental form of your local gymnasium. Those who see chess merely as a means of self-proof make the game experience uncomfortable and drive many of the better, more sensitive brains to analysis, correspondence, problems, studies and the like."

It is most probably that Radjabov found this natural improvement over the board, as he spend more than an hour, if I am not mistaken. But it could be that he was just trying to remember his own analysis (can you imagine how much he has to remember??).
