Pawn = princess because pawns usually promote to queens anyway and it sounds cooler. But a pawn isn't a piece so that doesn't count
If you could rename the chess pieces...

Pawns and king are included.

Knight would be paladin, bishop a sage or troubadour/Valkyrie, rook would be general, queen be queen and king be king.
(Fire emblem stolen names)

I would name them all Shecky! That's right, every last one of them--even the pawns!
lol

Pawns - Peasants
Rooks - Chariots
Knights - Cavalry
Bishop - Sage (stolen from kamuimaru, I think it sounds really cool)
Queen - Queen
King - I

Oh wait. I change. Rook are dragons, bishops Phoenixes, knights gryphons, queens nagas and kings kings.

Pawn: Shecky
Knights: Horsey
Bishop: Skinny
Rook: Fatty
Queen: Princessy
King: Princey
Shecky to e4!
Shecky to e6!
Shecky to d4!
Shecky to d5!
Shecky, kill that Shecky!
Shecky: Which Shecky?
That one, Shecky!
Shecky: Which one?
That Shecky on d5!
Say what??
...what would you rename them?
