More specifically; On a chess board how many total pieces can jump another piece. eg; 2 knights for each player = 4
I got this question at a bar trivia tonight and the MC said the answer was 4, which is incorrect because of 'castling'.
However, who jumps who during a castle? Do both the king and the rook jump each other, or just the rook, or just the king?
What is the answer?

When castling in an over the board game, I think you have to move your king to the desired square first and then move your rook. So it is the rook that jumps, though I would never describe it that way.

If you really must ask this, there's the Chess thread and Ask and Answer Stupid questions thread that both get plenty of activity.
King doesn't jump, since he can't pass through check, so he's like Hillary under sniper fire.

Basic answer is 4 (only knights), applied to the starting position. If you understand it "over the course of a game", you can add 4 rooks because of castling and 16 pawns that can promote to knights for a total of 24.

You can promote the pawns by capturing pieces as well, no need to capture other pawns. 4 pieces captures each side to get doubled pawns with a clear path, then you march them to promotion.

well you castle once for both sides thats 2 jumps by the rooks. 4 knights they can allways jump. The harder question is how many pawns can possibly get to the other side to promote to knights which is basicly impossible to prove unless you can get 10 knights for both sides which may be possible but im way to lazy to check. If its theoretically possible the answer should be: 26. With 24 knights allways able to jump and the one time jump from the castles.

To me, castling is more of a swap. So Ima have to say 4

ya i would say during castling, it's the rook that 'jumps' because there is no other way for it to get to the other side of the king. both pieces can't jump or else they would collide in midair :p
Under the strict touch-move rules enforced in most tournaments, castling is considered a king move. But under current US Chess Federation rules, a player who intends to castle and touches the rook first would suffer no penalty, and would be permitted to perform castling, provided castling is legal in the position. Still, the correct way to castle is to first move the king. (from wikipedia) either way, only one of the pieces jumps the other
whether or not the rook 'jumps' is a whole different matter which i cba thinking about

I would've answered 4, and I think it's pretty clear what the question meant.

Could an en passant be looked as a "jump"or not?

i dont think so, simply because an en passant isnt allowing the pawn to jump over an obstruction
