no prob, remember, its the opportunity is only there for one move...

It's French for "in passing" it means that if you move a pawn two squares forward then your opponent can capture it with a pawn - just as if it had only moved one square forward.

Your opponent can only do this on their very next move and only if they have a pawn advanced to the 4th rank, if black - or the 5th rank if white.

This rule came about a few hundred years ago when the rules of chess were changed to allow the pawns to move two squares on their first move....it got the game going faster....but with this "en passant" rule it meant people couldn't use the new two move advance to avoid capture. Hope this helps!

edit: wow, i got beat to the punch... : )


if i remember correctly, here is the basic history of it:

Castling and moving a pawn 2 on its first move came into the rules in European chess around the same time, and limitations were put on both. You probably already know you cannot castle out of check, or through check--the reasoning behind not castling through check was that even though he moved through several squares, the king only moves one square at a time, and thus would put himself in check along the way... but the pawn rule is just as easy and makes as much sense. For the one turn that you moved a pawn two, the pawns that could normally take it had it moved just one can take it IN PASSING (en passant), essentially, the pawn takes time to move, and can be killed on the way--however, if they do not en passant THAT TURN, he will have already arrived at his destination, and cannot be taken with en passant as he is no longer passing, but rather has already passed. You'd be amazed how many people have never even heard of en passant, and would challenge you if you tried it with them... most of them don't know a whole lot about chess, but a handfull of them do.

What kind?

Long John's are cool and I like chocolate ones with sprinkles on top and cream in the middle or the plain chocolate with no cream.

I thought the idea was that as in real warfare you wouldn't allow the leader to move through an area where the enemy sniper could get a free shot.

Wikipedia mentions the king castling through check and explains it like i did, wikipedia can be wrong, so i'd be curious to see if someone could find a sourced reasoning for it.
