He is actually signed up for 6 weeks in a row: Malaysia, Tokyo, Shanghai, Moscow, Basel, Paris .... crazy schedule that will mean he'll burn out like last year. I'm not sure why he signed up for Moscow .. unless he is planning to use this only if he goes out early in Shanghai & Tokyo. In best case scenario, I suspect he withdraws from Moscow.
He has two empty slots in non-mandatory's plus one zero. So he's probably trying to maximize his potential points. I also suspect a withdraw from Moscow if he goes deep in those before it.
