Cool thanks for posting. Wow, this is definitely the first topic ever on jeopardy where I actually knew every answer. Heck, I don't think I've ever known more than 1 or 2 answers for a topic before this.
Chess on Jeopardy!
( 400 )..." What are Bishops of opposie color " ?
( 800 )..." What is en passant " ?
(1200 ).." What is a stalemate " ?
(1600 ).." What is the French Defense " ?
( 2000 )." What is a pin " ?
1200 isn't necessarily stalemate: it could be a draw by threefold repetition, or a draw according to the 50-move rule.

Re: 1200
For those who didn't see it, it was one of those "video" answers where you see the board position and you see the guy moving the Queen to the d6 square, thereby forcing a stalemate.

I knew all of these! Believe it or not, I can usually answer about 50-75% of all the questions that are asked on the show. I can do it at home, but would most likely freeze up on stage!

Oh, I see. Living in England, I've never seen Jeopardy before. I've seen quite a few references to it though, on Family Guy for example.
Did anyone else see the Chess category on Jeopardy! tonight?
Category: Let's Talk Chess, Champs
400: Even with two extra pawns, white can't force a win here, because these pieces can travel only on opposite-colored squares
800: Literally "in passing", it's the 2-word term for how a pawn can capture another pawn that's moved past it
1200: White should have an easy win here, but he blows it by moving his queen to the D6 square, leading to this drawn outcome
1600: Initiated by the moves E4 E6, this defense got its name from its use by a Paris team in an 1834 match with London
2000: White can't move his knight, because doing so would expose his king; the knight's said to be stuck to the king with this tactic, named for a pointy little object
