Here is an interesting ramification about the En Passant rule:
Because of this rule, it is sometimes possible that the same position in terms of where the pieces are must occur FOUR TIMES, NOT THREE, to allow a draw claim.
Think about it!
In this position, White has a forced mate in 8, despite an apparent three-fold repetition:

... It's almost like it still hasn't been fully accepted yet. Then again, trying to explain it to my 8 year old step son wasn't the easiest of tasks...
"But that's cheating!!"
"Err... no, it's a legal move.. really."
So I can't blame my elders for leaving it for me to discover. Maybe I should have done the same. 😕
When chess was first invented the pawn could move one square straight forward if that square was unoccupied, or could capture one square diagonally forward (these options are of course still available). To speed the game up in the opening, the double square first move for pawns was introduced, (I think in the late 15th century), but it was felt that this should not allow a pawn using the double move to avoid a capture by an opposing pawn which was on it's own fifth rank. So the 'En Passant' capture was introduced to allow a capture as if the pawn had only moved one square, and since under the original laws it could have moved to it's fourth rank after a second move, this is why the capture is allowed only for one move. I hope this helps.

If 1...0-0, 2.Qxd7 and there is no good defense to 3.Qh7#2.Qb3 Ra8 2nd repetition 3.Bd3! threat 4.Qf7+ Kd8 5.Qf6+ Kc8 6.Bxa6+ and mates 3...Rh1+ 4.Bb1 Rh8 3rd repetition 5.Qc3! Now this works, because Black cannot castle on either side! 5...Rh7 6.Qf6 threating Nxh7 then Qe7. Black has no good defense and will be mated in 2 more moves.

Black to move
Black wins if there is no ep rule.
White wins if there is an ep rule.
So, the advocates for the 2-move rule only wanted to speed up the game without having an undue effect on things like endgame theory [and middlegame theory - this is one of the reasons a backward pawn is considered weak].
However.......
