Assuming a Huebner will be best here... (hoping to play e4!)

If black wants to open the c-file, I want a rook on it - I'm ample time ahead for such an idea.

lets just put all of our pieces in the middle of the board and see what gets in there way? K?

I'd like to keep the bishop pair, things are relatively open. I'm still ahead on the c-file, this pushes harder on the accelerator.

MINE. Blacks needless exchanges when he's behind on the c-file will cost...but where? Use the c-file silly! if the queen were on c2, then that bishop is in bigggg trouble... See the threat?

Leaving the c-file open to exploit, but still is advantageous on the long diagonal.

Two open files, and time.

...Horizon theory. There are only two open files, a rook on each would be appropriate. Better would be the a8 rook.
