Andernach Grasshopper / HurdleColourChanging Grasshopper (AG/hG): Like a normal Grasshopper but it changes the color of the piece it jumps over. (HurdleColourChanging property in Popeye)
Grasshopper(G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.
I fail to see D-O echo here. Can anybody explain me the elements?
(Maybe it is just WinChloe, that blindly compares whether moves played at the same time are D/O-O/D related and if mostly yes, then the program claims D-O echo. But the themes discovered by WinChloe have to be critically reviewed as a rule. Sometimes the claimed theme is there only as defined algorithm goes.)
