If Harry is a king, he can't win the game. A king cannot check a king.
The king has to be protected. The next most valuable piece which is 
obviously the centre of any strategy is the queen......

Now me:
A King cannot check a King.  Which is why Harry - The White King and 
LV - The Black King will not fight alone in the final battle.  They 
will both be joined by other pieces, one of which will be able to 
check and kill a king.

Harry will be joined by his White Knight - Neville and his White 
Bishop - Hermione (The keeper of knowledge).

LV will be joined by one other:  Bellatrix as the Black Queen. (Fits 
nicely doesn't it?)

The White Queen? - Lily Potter. Was lost.
The question is can the White Queen be reclaimed and give the White 
side a fighting chance? If so who will play her? Ginny, Luna perhaps 
even McGonagall?

Any thoughts on who some of the other players are?
