My favorite : the pawns becasue the pawns are the soul of chess like someone said.
I don't know about the least favorite. But it's at least it's not the qeen.
Favourite and Least Favourite Pieces
Sort:
What about the knight ? in some positions, the knight becomes far more powerful for the support of the queen than a rook. I myself sometimes sacrifice my rook for a knight, because knights can penetrate any position, while rooks can't. Plus, rooks can't fork. The revealed checks by knights create some of the nastiest traps in chess. For eg: the checkmate trap in the king's gambit ( my pet opening ).
Pawns a pretty good too - big things from small things grow!
Favourite Piece: Queen- I usually like to attack!
Least Favourite Piece: The Queenside Rook- Paul Morphy used to sack his queenside rook on move 0! It never came to attack.

My favorite piece is on e4 square (or on any other center square).
Least favorite is on h3 square (or on any other remoted square).
Marek - so you like any piece that is in the center?

Favorite. The king. It's what matters.
2nd Favorite: What TheBigDecline said.
Least favorite. The bishop. Sometimes I just want two of them on the same-color squares.
The king is what matters but really, a sitting duck. I don't really like kings, too
Really?? You like pawns better than queens?
Well, I guess Pawns can sometimes be stronger than queens
triple passed pawns on 7th rank> Queen + Rook!
My favourite piece is the one which delivers the mate 
favorites: king, rook, queen, pawns, knights and bishops.
pdve: which is your least favourite?
Favourite: Knight (because it can jump over pieces and move weird)
Least Favorite: Bishop (because all I see it doing is going up and going down diagnolly)
Favorite: Rook
Why: Tends to help the queen in my games.
Least favorite: pawns
Why: Those are very weak and always get eaten up
Favorite Piece: Queen
Least Favorite Piece: King
I guess it's because the queen is most powerful and king is the stupid dude who can't defend stuff for his own :D
i dont know developing a war machine while defending yourself from the invaders eems to hefty for a task; even though real life generals do that everyday for a living
