As I played with marine pieces, I did also something for the Springaren Summer Tourney that was dedicated to "still life" - problems with no captures and no checks (with importnat exception of final mates, of course). Echo mates are given by a white king, black king cannot run away due to scylla check or because of the Checkless chess condition.

Personal rating: C.

1.Kc4 SCe5 2.Rf5 Kb4 3.Rf4 SCd3#

1.Kd4 Kd5 2.Rf4 Kc4 3.Rg4 SCe5#

1.Ke4 SCg5 2.Rh6 Kd4 3.Rh4 SCf3#

That's just another expression of the same idea, one halfmove longer.

Personal rating: C.

1.Ge6 ROc4 2.Gb3 Kb5 3.Gb6 Ka6 4.Gg6 ROb6#

1.Kf5 ROg4 2.Gh5 ROa4 3.Kg6 Kb5 4.Kg5 ROc5#

Again the Checkless chess is used to freeze the bK on the line where he is mated. And naturally, there is a monochromatic echo...

Personal rating: D.

1.Gg7 Kc3 2.Ge5 ROg6 3.Kg7 ROc2 4.Gh8 ROd4#

1.Gc5 ROg6 2.Kf5 Kb5 3.Kg5 ROa6 4.Gh5 ROc5#

... but well, it is possible to show the same idea of mate diagonally and orthogonally - in the style of 14th TT CCM C 31.5.2004.

Personal rating: C.

1...Kb4 2.Ke5 Rf5 3.Kf4 Rc5 4.Gg4 Rc4#

1...Kd4 2.Ge4 Ke3 3.Ke7 Rf4 4.Ge8 Re4#

Still life 3-fold echo.
