Grasshopper Chess: Helpmate in 4

or 3½

To read the solutions and comments hold down the left mouse key and run the cursor across the blank area.

HELPMATES IN 3½

In a helpmate in 3½ white makes the first move, but the aim is still checkmate of the black king.
These problems are thus like set play in helpmates in 4 but without a preceding black key move.
Accordingly we show the solutions in the form 1... for comparison with helpmates in 4 with set play.
