A mate-in-five is easy. I'm curious what trick allows a mate-in-four.
2 black bishops = impossible mate
In a helpmate, both sides cooperate to help White mate Black. While this idea may seem slightly bizarre, helpmates are favorites of many over-the-board players, perhaps because normally they can only dream of such a cooperative opponent!
It's not impossible, it's just improbable.
