Well, just because there are possible last moves other than ...f5 doesn't make ep invalid it is invalid as a rule.... I think. That would make sense at least since black could have played ...f5. Anyway its all semantics and that isn't the point of the problem. The OP insisted a post a knight mate so I did (flawed but still a knight mate)
