This is a follow up to A knight chased by three knights
Two players are playing a variant of chess on a 11x11 grid. The first player controls a white knight that starts in the centre square. The second player controls four black knights that start in the corners. The first player aims to avoid being captured for as long as possible, while the second player aims to capture the white knight. Players alternate in making moves: the first player moves his white knight, then the second player moves all his black knights and so on. Passes are not allowed. The white knight is allowed to capture black knights.
If both players play optimally what would be the outcome of this game? Can white escape indefinitely? Can black guarantee to capture white no matter what he does?
