I tend to try and keep reasonably up to date with professional games, and some leave my jaw on the floor in places. Not always from the perspective of brilliance, so much as "I'd never have played that - I really don't understand Go so well!".
Here is a good case example, the following is the first 18 moves of a tournament game involving a 9p against a fellow professional. Question 1) What were the next two moves (one Black, one White, moves 19 and 20). Question 2) Why was this the right global area to play, and the right local position for the stone

) reasonable for a player aiming at a territorial game - white still needs to reduce black's framework if he's worried about it, and in the meantime black can run amok in white's territory. In this kind of game, neither player has to actively develop a moyo shape, but both players might instead work to destroy the opponent's territories. I don't know if this is even a good idea here, but it seems okay to me.
was played before (by Yoda???), and caused a stir. It looks like a pretty good place for White to reduce, so, on the theory that my opponent's good play is my good play, why not? 
where it said "Gu Li separates strongly" or something to that effect. It makes me wonder what exactly the pro had read that he felt that was bigger than anything else on the board. It goes against the corners -> sides -> center philosophy, it feels like a very loose move, it doesn't really feel big compared to the top left corner.
