King, any of the other pieces can be sacrificed with benefit.
If you could be a chess piece?

Queen because it's the most powerful piece, although I'd draw the line at having to undergo a sex change operation in order to become a Queen.

I'd be a bishop because it guarentees a place in heaven. Although I would suffer during this mortal life from moving only in diagonal lines and constantly searching for h7 squares in order to sacrifice myself for the greater good. THE GREATER GOOD...

"Pawn in Perpetual Promotion" -by learningthemoves
Of all the chess pieces to be, I would be the pawn in promotion.
Here's why:
Having traversed the board and pushed on through passed all the ranks, I've already fulfilled my intended purpose successfully, so thanks.
Now, after pawn-life, the real fun begins...
I can still remember what it's like to be only a pawn, but never will I be a pawn again!
And I have some attractive upgrade options for my new glorified body...B,R,Q,K

I would be the King, obvious reasons : )
so you can choose to only move if you have to.
thought George would want to be the "Best" piece.

The whole reason of the game...is the King..makes the whole debate go to the bing..Who is lion hearted like a king? Knowing the two propable ends of the non ending(!) game..End can be won or lost..Let us say, that he got one of the ends...The Others of the Island can't know, for him what the end did cost? The fear of the past, and the anxiety of the future makes people choose all the pieces leaving the King way out...Don't look at the King standing there passive(even when his time comes for the move)...He the one who wins and loses when one of the people of him wins and loses..He the one who feels..The whole game is for him..Who wants to be an eye or hand, when there is a choice like using the soul and body both..For the King, Cheers! (I can't believe I'm saying these words, a box full of fears 8O...Let us make a new beginning hence let's live the present tense with a 100% consciousness..
Like the movie tron. If you could be any chess piece and why?
