I'm not a big chess person but I was confused why Zero didn't take options 1, 2 or 3.
He backed off and hid behind the pawn which was possibly the worst move imaginable.
What happened to the "Fu fu fu, JUST AS PLANNED:
Goddamit. Zero instigated the King movement to begin with. He could have at least called a draw or resigned. Lelouch seems to be weakest when family comes into play.
