This first question was closed as a duplicate of the second.
The first asks what it is called in chess when a pawn captures another pawn by passing it. The second asks what the "En Passant" rule is in chess.
Yes, these questions are related. Yes, the answer to the second answers the first. But that doesn't seem like it makes them the same question. The two questions are actually reasonable answers to each other. This is how you know they are not asking the same thing.
Is this how it is supposed to work? Even though the asker would have had to already know the answer to the question to identify the second question as the answer that was desired, it gets deemed to be the same question?
