It's all about the queen !
Usually we try to beat our opponents when we play a game of chess, but in Helpmate problems we actually try to help them achieve mate.
In this position Black moves first to help White checkmate in the next move. Solution
Then there are Double Whammy problems where White makes 2 moves in a row to checkmate the black king - the first move may not be a check
And of course we dream of making a classic queen sacrifice
